### 接口安全 时效性+签名+数据加密 ###

*  导入maven依赖
 *  实现思路
 *   *  show you the code
     *   *  定义注解类
         *  注解类业务代码实现
         *  需要安全校验的接口添加注解使用
         *  SignUtil代码（时效性校验，生成签名，验证签名）

# 导入maven依赖 #

<dependency>
        <groupId>commons-codec</groupId>
        <artifactId>commons-codec</artifactId>
        <version>1.11</version>
    </dependency>
    
    <dependency>
        <groupId>org.bouncycastle</groupId>
        <artifactId>bcprov-jdk15</artifactId>
        <version>1.46</version>
    </dependency>

# 实现思路 #

1、所有接口通过注解+aop实现接口时效性、验证签名  
2、具体业务接口再解密数据，然后进行业务代码处理逻辑

这里贴出简单的代码(在注解中实现接口时效性校验)，以及验证签名的代码片段，数据解密部分的代码  
可以自己实现，就不贴代码啦

## show you the code ##

### 定义注解类 ###

package com.pica.cloud.commercialization.crrs.interceptor;
    
    import java.lang.annotation.*;
    
    /** * @ClassName SecurityAuth * @Description * @Author Chongwen.jiang * @Date 2019/8/26 10:46 * @ModifyDate 2019/8/26 10:46 * @Version 1.0 */
    @Target({ ElementType.TYPE, ElementType.METHOD})
    @Retention(RetentionPolicy.RUNTIME)
    @Documented
    public @interface SecurityAuth { 
    
    }

### 注解类业务代码实现 ###

        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { 
            if (handler instanceof HandlerMethod) { 
                HandlerMethod handlerMethod = (HandlerMethod) handler;
                Annotation securityAuth = handlerMethod.getMethod().getAnnotation(SecurityAuth.class);
                if (securityAuth == null) { 
                    securityAuth = handlerMethod.getMethod().getDeclaringClass().getAnnotation(SecurityAuth.class);
                }
                if (securityAuth != null) { 
                    String invokeTime = request.getHeader("invokeTime");
                    String sign = request.getHeader("sign");
                    log.info("getHeaderParamenters===>time:{}, sign:{}", invokeTime, sign);
                    if(StringUtils.isNotEmpty(invokeTime) && StringUtils.isNotEmpty(sign)) { 
                        if(!Signutil.interfaceSecurityAuth(Long.valueOf(invokeTime), sign)) { 
                            sendJsonMessage(response, PARAMETERS_ILLEGAL);
                            return false;
                        }
                    } else { 
                        sendJsonMessage(response, PARAMETERS_ILLEGAL);
                        return false;
                    }
                }
            }
            return true;
        }
    
        private void sendJsonMessage(HttpServletResponse response, String body) throws Exception { 
            response.setContentType("application/json; charset=utf-8");
            PrintWriter writer = response.getWriter();
            writer.print(body);
            writer.close();
            response.flushBuffer();
        }
    
    
    }
