测试shiro的quickstart

约定不等于承诺〃 2022-07-11 13:13 132阅读 0赞

第一步：新建Java工程shiro\_quickstart，新建lib文件夹，导入jar文件：

　　在src目录下新建文件log4j.properties：

在src目录下新建文件shiro.ini：

    # =============================================================================
    # Quickstart INI Realm configuration
    #
    # For those that might not understand the references in this file, the
    # definitions are all based on the classic Mel Brooks' film "Spaceballs". ;)
    # =============================================================================
    
    # -----------------------------------------------------------------------------
    # Users and their assigned roles
    #
    # Each line conforms to the format defined in the
    # org.apache.shiro.realm.text.TextConfigurationRealm#setUserDefinitions JavaDoc
    # -----------------------------------------------------------------------------
    [users]
    # user 'root' with password 'secret' and the 'admin' role
    root = secret, admin
    # user 'guest' with the password 'guest' and the 'guest' role
    guest = guest, guest
    # user 'presidentskroob' with password '12345' ("That's the same combination on
    # my luggage!!!" ;)), and role 'president'
    presidentskroob = 12345, president
    # user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'
    darkhelmet = ludicrousspeed, darklord, schwartz
    # user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
    lonestarr = vespa, goodguy, schwartz
    
    # -----------------------------------------------------------------------------
    # Roles with assigned permissions
    # 
    # Each line conforms to the format defined in the
    # org.apache.shiro.realm.text.TextConfigurationRealm#setRoleDefinitions JavaDoc
    # -----------------------------------------------------------------------------
    [roles]
    # 'admin' role has all permissions, indicated by the wildcard '*'
    admin = *
    # The 'schwartz' role can do anything (*) with any lightsaber:
    schwartz = lightsaber:*
    # The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with
    # license plate 'eagle5' (instance specific id)
    goodguy = winnebago:drive:eagle5

其中，\[users\]和\[roles\]定义了用户和角色，这会在下面的测试代码中用到。  
　　在\[users\]下，lonestarr = vespa, goodguy, schwartz代表的意义是：用户lonestarr的凭证（密码）是vespa，该用户含有goodguy和schwartz这两个角色。  
　　在\[roles\]下，goodguy = winnebago:drive:eagle5代表的意义是：允许角色goodguy对类型为winnebago的实体eagle5执行drive操作。  
　　  
　　新建好文件后的工程如下图所示：

　　第二步：新建包com.shiro.test，在该包下新建类Quickstart.java：

package com.shiro.test;
    
    
    import org.apache.shiro.SecurityUtils;
    import org.apache.shiro.authc.*;
    import org.apache.shiro.config.IniSecurityManagerFactory;
    import org.apache.shiro.mgt.SecurityManager;
    import org.apache.shiro.session.Session;
    import org.apache.shiro.subject.Subject;
    import org.apache.shiro.util.Factory;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    
    /** * Simple Quickstart application showing how to use Shiro's API. * * @since 0.9 RC2 */
    public class Quickstart { 
    
        private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);
    
    
        public static void main(String[] args) {
    
            // The easiest way to create a Shiro SecurityManager with configured
            // realms, users, roles and permissions is to use the simple INI config.
            // We'll do that by using a factory that can ingest a .ini file and
            // return a SecurityManager instance:
    
            // Use the shiro.ini file at the root of the classpath
            // (file: and url: prefixes load from files and urls respectively):
            Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
            SecurityManager securityManager = factory.getInstance();
    
            // for this simple example quickstart, make the SecurityManager
            // accessible as a JVM singleton. Most applications wouldn't do this
            // and instead rely on their container configuration or web.xml for
            // webapps. That is outside the scope of this simple quickstart, so
            // we'll just do the bare minimum so you can continue to get a feel
            // for things.
            SecurityUtils.setSecurityManager(securityManager);
    
            // Now that a simple Shiro environment is set up, let's see what you can do:
    
            // get the currently executing user:
            // 获取当前的 Subject. 调用 SecurityUtils.getSubject();
            Subject currentUser = SecurityUtils.getSubject();
    
            // Do some stuff with a Session (no need for a web or EJB container!!!)
            // 测试使用 Session 
            // 获取 Session: Subject#getSession()
            Session session = currentUser.getSession();
            session.setAttribute("someKey", "aValue");
            String value = (String) session.getAttribute("someKey");
            if (value.equals("aValue")) {
                log.info("---> Retrieved the correct value! [" + value + "]");
            }
    
            // let's login the current user so we can check against roles and permissions:
            // 测试当前的用户是否已经被认证. 即是否已经登录. 
            // 调动 Subject 的 isAuthenticated() 
            if (!currentUser.isAuthenticated()) {
                // 把用户名和密码封装为 UsernamePasswordToken 对象
                UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
                // rememberme
                token.setRememberMe(true);
                try {
                    // 执行登录. 
                    currentUser.login(token);
                } 
                // 若没有指定的账户, 则 shiro 将会抛出 UnknownAccountException 异常. 
                catch (UnknownAccountException uae) {
                    log.info("----> There is no user with username of " + token.getPrincipal());
                    return; 
                } 
                // 若账户存在, 但密码不匹配, 则 shiro 会抛出 IncorrectCredentialsException 异常。 
                catch (IncorrectCredentialsException ice) {
                    log.info("----> Password for account " + token.getPrincipal() + " was incorrect!");
                    return; 
                } 
                // 用户被锁定的异常 LockedAccountException
                catch (LockedAccountException lae) {
                    log.info("The account for username " + token.getPrincipal() + " is locked. " +
                            "Please contact your administrator to unlock it.");
                }
                // ... catch more exceptions here (maybe custom ones specific to your application?
                // 所有认证时异常的父类. 
                catch (AuthenticationException ae) {
                    //unexpected condition? error?
                }
            }
    
            //say who they are:
            //print their identifying principal (in this case, a username):
            log.info("----> User [" + currentUser.getPrincipal() + "] logged in successfully.");
    
            //test a role:
            // 测试是否有某一个角色. 调用 Subject 的 hasRole 方法. 
            if (currentUser.hasRole("schwartz")) {
                log.info("----> May the Schwartz be with you!");
            } else {
                log.info("----> Hello, mere mortal.");
                return; 
            }
    
            //test a typed permission (not instance-level)
            // 测试用户是否具备某一个行为. 调用 Subject 的 isPermitted() 方法。 
            if (currentUser.isPermitted("lightsaber:weild")) {
                log.info("----> You may use a lightsaber ring. Use it wisely.");
            } else {
                log.info("Sorry, lightsaber rings are for schwartz masters only.");
            }
    
            //a (very powerful) Instance Level permission:
            // 测试用户是否具备某一个行为. 
            if (currentUser.isPermitted("winnebago:drive:eagle5")) {
                log.info("----> You are permitted to 'drive' the winnebago with license plate (id) 'eagle5'. " +
                        "Here are the keys - have fun!");
            } else {
                log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");
            }
    
            //all done - log out!
            // 执行登出. 调用 Subject 的 Logout() 方法. 
            System.out.println("---->" + currentUser.isAuthenticated());
    
            currentUser.logout();
    
            System.out.println("---->" + currentUser.isAuthenticated());
    
            System.exit(0);
        }
    }

第三步：运行程序，可以在控制台打印出相应的测试信息。
