 *   *  1，添加License校验类需要的参数
     *  2，添加Listener，用于在项目启动的时候安装License证书
     *  3，添加拦截器，用于在登录的时候校验License证书
     *  4，添加登录页面并测试

# 一，简介 #

License，即版权许可证，一般用于收费软件给付费用户提供的访问许可证明。根据应用部署位置的不同，一般可以分为以下两种情况讨论：

*  应用部署在开发者自己的云服务器上。这种情况下用户通过账号登录的形式远程访问，因此只需要在账号登录的时候校验目标账号的有效期、访问权限等信息即可。
 *  应用部署在客户的内网环境。因为这种情况开发者无法控制客户的网络环境，也不能保证应用所在服务器可以访问外网，因此通常的做法是使用服务器许可文件，在应用启动的时候加载证书，然后在登录或者其他关键操作的地方校验证书的有效性。

# 二， 使用 TrueLicense 生成License #

## 1，在pom.xml中添加关键依赖 ##

<dependency>
        <groupId>de.schlichtherle.truelicense</groupId>
        <artifactId>truelicense-core</artifactId>
        <version>1.33</version>
        <scope>provided</scope>
    </dependency>

## 2，校验自定义的License参数 ##

`TrueLicense`的 `de.schlichtherle.license.LicenseManager`类自带的`verify`方法只校验了我们后面颁发的许可文件的生效和过期时间，然而在实际项目中我们可能需要额外校验应用部署的服务器的IP地址、MAC地址、CPU序列号、主板序列号等信息，因此我们需要复写框架的部分方法以实现校验自定义参数的目的。

首先需要添加一个自定义的可被允许的服务器硬件信息的实体类（如果校验其他参数，可自行补充）：

package cn.zifangsky.license;
    
    import java.io.Serializable;
    import java.util.List;
    
    /** * 自定义需要校验的License参数 * * @author zifangsky * @date 2018/4/23 * @since 1.0.0 */
    public class LicenseCheckModel implements Serializable{ 
    
        private static final long serialVersionUID = 8600137500316662317L;
        /** * 可被允许的IP地址 */
        private List<String> ipAddress;
    
        /** * 可被允许的MAC地址 */
        private List<String> macAddress;
    
        /** * 可被允许的CPU序列号 */
        private String cpuSerial;
    
        /** * 可被允许的主板序列号 */
        private String mainBoardSerial;
    
        //省略setter和getter方法
    
        @Override
        public String toString() { 
            return "LicenseCheckModel{" +
                    "ipAddress=" + ipAddress +
                    ", macAddress=" + macAddress +
                    ", cpuSerial='" + cpuSerial + '\'' +
                    ", mainBoardSerial='" + mainBoardSerial + '\'' +
                    '}';
        }
    }

其次，添加一个`License`生成类需要的参数：

package cn.zifangsky.license;
    
    import com.fasterxml.jackson.annotation.JsonFormat;
    
    import java.io.Serializable;
    import java.util.Date;
    
    /** * License生成类需要的参数 * * @author zifangsky * @date 2018/4/19 * @since 1.0.0 */
    public class LicenseCreatorParam implements Serializable { 
    
        private static final long serialVersionUID = -7793154252684580872L;
        /** * 证书subject */
        private String subject;
    
        /** * 密钥别称 */
        private String privateAlias;
    
        /** * 密钥密码（需要妥善保管，不能让使用者知道） */
        private String keyPass;
    
        /** * 访问秘钥库的密码 */
        private String storePass;
    
        /** * 证书生成路径 */
        private String licensePath;
    
        /** * 密钥库存储路径 */
        private String privateKeysStorePath;
    
        /** * 证书生效时间 */
        @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
        private Date issuedTime = new Date();
    
        /** * 证书失效时间 */
        @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
        private Date expiryTime;
    
        /** * 用户类型 */
        private String consumerType = "user";
    
        /** * 用户数量 */
        private Integer consumerAmount = 1;
    
        /** * 描述信息 */
        private String description = "";
    
        /** * 额外的服务器硬件校验信息 */
        private LicenseCheckModel licenseCheckModel;
    
        //省略setter和getter方法
    
        @Override
        public String toString() { 
            return "LicenseCreatorParam{" +
                    "subject='" + subject + '\'' +
                    ", privateAlias='" + privateAlias + '\'' +
                    ", keyPass='" + keyPass + '\'' +
                    ", storePass='" + storePass + '\'' +
                    ", licensePath='" + licensePath + '\'' +
                    ", privateKeysStorePath='" + privateKeysStorePath + '\'' +
                    ", issuedTime=" + issuedTime +
                    ", expiryTime=" + expiryTime +
                    ", consumerType='" + consumerType + '\'' +
                    ", consumerAmount=" + consumerAmount +
                    ", description='" + description + '\'' +
                    ", licenseCheckModel=" + licenseCheckModel +
                    '}';
        }
    }

最后是License生成类，用于生成License证书：

package cn.zifangsky.license;

        private LicenseCreatorParam param;

            this.param = param;
        }

                licenseManager.store(licenseContent,new File(param.getLicensePath()));
    
                return true;
            }catch (Exception e){ 
                logger.error(MessageFormat.format("证书生成失败：{0}",param),e);
                return false;
            }
        }
    
        /** * 初始化证书生成参数 * @author zifangsky * @date 2018/4/20 10:56 * @since 1.0.0 * @return de.schlichtherle.license.LicenseParam */

            Preferences preferences = Preferences.userNodeForPackage(LicenseCreator.class);
    
            //设置对证书内容加密的秘钥
            CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());
    
            KeyStoreParam privateStoreParam = new CustomKeyStoreParam(LicenseCreator.class
                    ,param.getPrivateKeysStorePath()
                    ,param.getPrivateAlias()
                    ,param.getStorePass()
                    ,param.getKeyPass());
    
            LicenseParam licenseParam = new DefaultLicenseParam(param.getSubject()
                    ,preferences
                    ,privateStoreParam
                    ,cipherParam);
    
            return licenseParam;
        }
    
        /** * 设置证书生成正文信息 * @author zifangsky * @date 2018/4/20 10:57 * @since 1.0.0 * @return de.schlichtherle.license.LicenseContent */
        private LicenseContent initLicenseContent(){ 
            LicenseContent licenseContent = new LicenseContent();
            licenseContent.setHolder(DEFAULT_HOLDER_AND_ISSUER);
            licenseContent.setIssuer(DEFAULT_HOLDER_AND_ISSUER);
    
            licenseContent.setSubject(param.getSubject());
            licenseContent.setIssued(param.getIssuedTime());
            licenseContent.setNotBefore(param.getIssuedTime());

            licenseContent.setExtra(param.getLicenseCheckModel());
    
            return licenseContent;
        }
    
    }

## 3，添加一个生成证书的Controller： ##

这个Controller对外提供了两个RESTful接口，分别是「获取服务器硬件信息」和「生成证书」，示例代码如下：

package cn.zifangsky.controller;
    
    import cn.zifangsky.license.AbstractServerInfos;
    import cn.zifangsky.license.LicenseCheckModel;
    import cn.zifangsky.license.LicenseCreator;
    import cn.zifangsky.license.LicenseCreatorParam;
    import cn.zifangsky.license.LinuxServerInfos;
    import cn.zifangsky.license.WindowsServerInfos;
    import org.apache.commons.lang3.StringUtils;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.http.MediaType;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.RestController;
    
    import java.util.HashMap;
    import java.util.Map;
    
    /** * * 用于生成证书文件，不能放在给客户部署的代码里 * @author zifangsky * @date 2018/4/26 * @since 1.0.0 */
    @RestController
    @RequestMapping("/license")
    public class LicenseCreatorController { 
    
        /** * 证书生成路径 */
        @Value("${license.licensePath}")
        private String licensePath;
    
        /** * 获取服务器硬件信息 * @author zifangsky * @date 2018/4/26 13:13 * @since 1.0.0 * @param osName 操作系统类型，如果为空则自动判断 * @return com.ccx.models.license.LicenseCheckModel */
        @RequestMapping(value = "/getServerInfos",produces = { MediaType.APPLICATION_JSON_UTF8_VALUE})
        public LicenseCheckModel getServerInfos(@RequestParam(value = "osName",required = false) String osName) { 
            //操作系统类型
            if(StringUtils.isBlank(osName)){ 
                osName = System.getProperty("os.name");
            }
            osName = osName.toLowerCase();
    
            AbstractServerInfos abstractServerInfos = null;
    
            //根据不同操作系统类型选择不同的数据获取方法
            if (osName.startsWith("windows")) { 
                abstractServerInfos = new WindowsServerInfos();
            } else if (osName.startsWith("linux")) { 
                abstractServerInfos = new LinuxServerInfos();
            }else{ //其他服务器类型
                abstractServerInfos = new LinuxServerInfos();
            }
    
            return abstractServerInfos.getServerInfos();
        }
    
        /** * 生成证书 * @author zifangsky * @date 2018/4/26 13:13 * @since 1.0.0 * @param param 生成证书需要的参数，如：{"subject":"ccx-models","privateAlias":"privateKey","keyPass":"5T7Zz5Y0dJFcqTxvzkH5LDGJJSGMzQ","storePass":"3538cef8e7","licensePath":"C:/Users/zifangsky/Desktop/license.lic","privateKeysStorePath":"C:/Users/zifangsky/Desktop/privateKeys.keystore","issuedTime":"2018-04-26 14:48:12","expiryTime":"2018-12-31 00:00:00","consumerType":"User","consumerAmount":1,"description":"这是证书描述信息","licenseCheckModel":{"ipAddress":["192.168.245.1","10.0.5.22"],"macAddress":["00-50-56-C0-00-01","50-7B-9D-F9-18-41"],"cpuSerial":"BFEBFBFF000406E3","mainBoardSerial":"L1HF65E00X9"}} * @return java.util.Map<java.lang.String,java.lang.Object> */
        @RequestMapping(value = "/generateLicense",produces = { MediaType.APPLICATION_JSON_UTF8_VALUE})
        public Map<String,Object> generateLicense(@RequestBody(required = true) LicenseCreatorParam param) { 
            Map<String,Object> resultMap = new HashMap<>(2);
    
            if(StringUtils.isBlank(param.getLicensePath())){ 
                param.setLicensePath(licensePath);
            }
    
            LicenseCreator licenseCreator = new LicenseCreator(param);
            boolean result = licenseCreator.generateLicense();
    
            if(result){ 
                resultMap.put("result","ok");
                resultMap.put("msg",param);
            }else{ 
                resultMap.put("result","error");
                resultMap.put("msg","证书文件生成失败！");
            }
            return resultMap;
        }
    }

# 三，使用JDK自带的 keytool 工具生成公私钥证书库 #

假如我们设置公钥库密码为：public\_password1234，私钥库密码为：private\_password1234，则生成命令如下：

#生成命令
    keytool -genkeypair -keysize 1024 -validity 3650 -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -keypass "private_password1234" -dname "CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN"
    
    #导出命令
    keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -file "certfile.cer"
    
    #导入命令
    keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"

上述命令执行完成之后，会在当前路径下生成三个文件，分别是：`privateKeys.keystore`、`publicCerts.keystore`、`certfile.cer`。其中文件`certfile.cer`不再需要可以删除，文件`privateKeys.keystore`用于当前的 `ServerDemo`项目给客户生成`license`文件，而文件`publicCerts.keystore`则随应用代码部署到客户服务器，用户解密`license`文件并校验其许可信息。

# 四，为客户生成license文件 #

将 ServerDemo 项目部署到客户服务器，通过以下接口获取服务器的硬件信息（等license文件生成后需要删除这个项目。当然也可以通过命令手动获取客户服务器的硬件信息，然后在开发者自己的电脑上生成license文件）：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwMTk2NQ_size_16_color_FFFFFF_t_70]  
然后生成license文件：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwMTk2NQ_size_16_color_FFFFFF_t_70 1]  
请求时需要在Header中添加一个 Content-Type ，其值为：application/json;charset=UTF-8。参数示例如下：

{ 
    	"subject": "license_demo",
    	"privateAlias": "privateKey",
    	"keyPass": "private_password1234",
    	"storePass": "public_password1234",
    	"licensePath": "C:/Users/zifangsky/Desktop/license_demo/license.lic",
    	"privateKeysStorePath": "C:/Users/zifangsky/Desktop/license_demo/privateKeys.keystore",
    	"issuedTime": "2018-07-10 00:00:01",
    	"expiryTime": "2019-12-31 23:59:59",
    	"consumerType": "User",
    	"consumerAmount": 1,
    	"description": "这是证书描述信息",
    	"licenseCheckModel": { 
    		"ipAddress": ["192.168.245.1", "10.0.5.22"],
    		"macAddress": ["00-50-56-C0-00-01", "50-7B-9D-F9-18-41"],
    		"cpuSerial": "BFEBFBFF000406E3",
    		"mainBoardSerial": "L1HF65E00X9"
    	}
    }

如果请求成功，那么最后会在`licensePath` 参数设置的路径生成一个`license.lic`的文件，这个文件就是给客户部署代码的服务器许可文件。

# 五，给客户部署的应用中添加License校验 #

## 1，添加License校验类需要的参数 ##

package cn.zifangsky.license;
    
    /** * License校验类需要的参数 * * @author zifangsky * @date 2018/4/20 * @since 1.0.0 */
    public class LicenseVerifyParam { 
    
        /** * 证书subject */
        private String subject;
    
        /** * 公钥别称 */
        private String publicAlias;
    
        /** * 访问公钥库的密码 */
        private String storePass;
    
        /** * 证书生成路径 */
        private String licensePath;
    
        /** * 密钥库存储路径 */
        private String publicKeysStorePath;
    
        public LicenseVerifyParam() { 
    
        }
    
        public LicenseVerifyParam(String subject, String publicAlias, String storePass, String licensePath, String publicKeysStorePath) { 
            this.subject = subject;
            this.publicAlias = publicAlias;
            this.storePass = storePass;
            this.licensePath = licensePath;
            this.publicKeysStorePath = publicKeysStorePath;
        }
    
        //省略setter和getter方法
    
        @Override
        public String toString() { 
            return "LicenseVerifyParam{" +
                    "subject='" + subject + '\'' +
                    ", publicAlias='" + publicAlias + '\'' +
                    ", storePass='" + storePass + '\'' +
                    ", licensePath='" + licensePath + '\'' +
                    ", publicKeysStorePath='" + publicKeysStorePath + '\'' +
                    '}';
        }
    }

然后再添加License校验类：

package cn.zifangsky.license;
    
    import de.schlichtherle.license.*;
    import org.apache.logging.log4j.LogManager;
    import org.apache.logging.log4j.Logger;
    
    import java.io.File;
    import java.text.DateFormat;
    import java.text.MessageFormat;
    import java.text.SimpleDateFormat;
    import java.util.prefs.Preferences;
    
    /** * License校验类 * * @author zifangsky * @date 2018/4/20 * @since 1.0.0 */
    public class LicenseVerify { 
        private static Logger logger = LogManager.getLogger(LicenseVerify.class);
    
        /** * 安装License证书 * @author zifangsky * @date 2018/4/20 16:26 * @since 1.0.0 */
        public synchronized LicenseContent install(LicenseVerifyParam param){ 
            LicenseContent result = null;
            DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    
            //1. 安装证书
            try{ 
                LicenseManager licenseManager = LicenseManagerHolder.getInstance(initLicenseParam(param));
                licenseManager.uninstall();
    
                result = licenseManager.install(new File(param.getLicensePath()));
                logger.info(MessageFormat.format("证书安装成功，证书有效期：{0} - {1}",format.format(result.getNotBefore()),format.format(result.getNotAfter())));
            }catch (Exception e){ 
                logger.error("证书安装失败！",e);
            }
    
            return result;
        }
    
        /** * 校验License证书 * @author zifangsky * @date 2018/4/20 16:26 * @since 1.0.0 * @return boolean */
        public boolean verify(){ 
            LicenseManager licenseManager = LicenseManagerHolder.getInstance(null);
            DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    
            //2. 校验证书
            try { 
                LicenseContent licenseContent = licenseManager.verify();
    // System.out.println(licenseContent.getSubject());
    
                logger.info(MessageFormat.format("证书校验通过，证书有效期：{0} - {1}",format.format(licenseContent.getNotBefore()),format.format(licenseContent.getNotAfter())));
                return true;
            }catch (Exception e){ 
                logger.error("证书校验失败！",e);
                return false;
            }
        }
    
        /** * 初始化证书生成参数 * @author zifangsky * @date 2018/4/20 10:56 * @since 1.0.0 * @param param License校验类需要的参数 * @return de.schlichtherle.license.LicenseParam */
        private LicenseParam initLicenseParam(LicenseVerifyParam param){ 
            Preferences preferences = Preferences.userNodeForPackage(LicenseVerify.class);
    
            CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());
    
            KeyStoreParam publicStoreParam = new CustomKeyStoreParam(LicenseVerify.class
                    ,param.getPublicKeysStorePath()
                    ,param.getPublicAlias()
                    ,param.getStorePass()
                    ,null);
    
            return new DefaultLicenseParam(param.getSubject()
                    ,preferences
                    ,publicStoreParam
                    ,cipherParam);
        }
    
    }

## 2，添加Listener，用于在项目启动的时候安装License证书 ##

package cn.zifangsky.license;
    
    import org.apache.commons.lang3.StringUtils;
    import org.apache.logging.log4j.LogManager;
    import org.apache.logging.log4j.Logger;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.ApplicationListener;
    import org.springframework.context.event.ContextRefreshedEvent;
    import org.springframework.stereotype.Component;
    
    /** * 在项目启动时安装证书 * * @author zifangsky * @date 2018/4/24 * @since 1.0.0 */
    @Component
    public class LicenseCheckListener implements ApplicationListener<ContextRefreshedEvent> { 
        private static Logger logger = LogManager.getLogger(LicenseCheckListener.class);
    
        /** * 证书subject */
        @Value("${license.subject}")
        private String subject;
    
        /** * 公钥别称 */
        @Value("${license.publicAlias}")
        private String publicAlias;
    
        /** * 访问公钥库的密码 */
        @Value("${license.storePass}")
        private String storePass;
    
        /** * 证书生成路径 */
        @Value("${license.licensePath}")
        private String licensePath;
    
        /** * 密钥库存储路径 */
        @Value("${license.publicKeysStorePath}")
        private String publicKeysStorePath;
    
        @Override
        public void onApplicationEvent(ContextRefreshedEvent event) { 
            //root application context 没有parent
            ApplicationContext context = event.getApplicationContext().getParent();
            if(context == null){ 
                if(StringUtils.isNotBlank(licensePath)){ 
                    logger.info("++++++++ 开始安装证书 ++++++++");
    
                    LicenseVerifyParam param = new LicenseVerifyParam();
                    param.setSubject(subject);
                    param.setPublicAlias(publicAlias);
                    param.setStorePass(storePass);
                    param.setLicensePath(licensePath);
                    param.setPublicKeysStorePath(publicKeysStorePath);
    
                    LicenseVerify licenseVerify = new LicenseVerify();
                    //安装证书
                    licenseVerify.install(param);
    
                    logger.info("++++++++ 证书安装结束 ++++++++");
                }
            }
        }
    }

注：上面代码使用参数信息如下所示：

#License相关配置
    license.subject=license_demo
    license.publicAlias=publicCert
    license.storePass=public_password1234
    license.licensePath=C:/Users/zifangsky/Desktop/license_demo/license.lic
    license.publicKeysStorePath=C:/Users/zifangsky/Desktop/license_demo/publicCerts.keystore

## 3，添加拦截器，用于在登录的时候校验License证书 ##

package cn.zifangsky.license;
    
    import com.alibaba.fastjson.JSON;
    import org.apache.logging.log4j.LogManager;
    import org.apache.logging.log4j.Logger;
    import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.util.HashMap;
    import java.util.Map;
    
    /** * LicenseCheckInterceptor * * @author zifangsky * @date 2018/4/25 * @since 1.0.0 */
    public class LicenseCheckInterceptor extends HandlerInterceptorAdapter{ 
        private static Logger logger = LogManager.getLogger(LicenseCheckInterceptor.class);
    
        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { 
            LicenseVerify licenseVerify = new LicenseVerify();
    
            //校验证书是否有效
            boolean verifyResult = licenseVerify.verify();
    
            if(verifyResult){ 
                return true;
            }else{ 
                response.setCharacterEncoding("utf-8");
                Map<String,String> result = new HashMap<>(1);
                result.put("result","您的证书无效，请核查服务器是否取得授权或重新申请证书！");
    
                response.getWriter().write(JSON.toJSONString(result));
    
                return false;
            }
        }
    
    }

## 4，添加登录页面并测试 ##

            </div>
        </div>
    </div>
    </body>
    </html>

启动项目，可以发现之前生成的license证书可以正常使用：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwMTk2NQ_size_16_color_FFFFFF_t_70 2]  
这时访问 http://127.0.0.1:7080/login ，可以正常登录：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDAwMTk2NQ_size_16_color_FFFFFF_t_70 3]  
重新生成license证书，并设置很短的有效期。  
重新启动ClientDemo，并再次登录，可以发现爆以下提示信息：
