使用 test  完成最基本简单的认证流程。

> ### 1、认证流程  ###

1、创建 securityManager

2、主体(subject) 提交请求

3、securityManager 认证

4、Authenticator 认证

5、Realm 验证

> ### 2、引入依赖 ###

<dependency>
          <groupId>org.apache.shiro</groupId>
          <artifactId>shiro-core</artifactId>
          <version>1.6.0</version>
        </dependency>
    
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>4.12</version>
          <scope>test</scope>
        </dependency>

--------------------

> ### 3、 编写测试代码 ###

package ch.shiro.test;
    
    import org.apache.shiro.SecurityUtils;
    import org.apache.shiro.authc.AuthenticationToken;
    import org.apache.shiro.authc.UsernamePasswordToken;
    import org.apache.shiro.mgt.DefaultSecurityManager;
    import org.apache.shiro.realm.SimpleAccountRealm;
    import org.apache.shiro.subject.Subject;
    import org.junit.Before;
    import org.junit.Test;
    
    /**

     */
    public class AuthenticationTest {
    
      // realm
      SimpleAccountRealm simpleAccountRealm = new SimpleAccountRealm();
    
      @Before
      public void addUser() {
        // 给realm 赋值 account
        simpleAccountRealm.addAccount("ch", "123");
      }
    
      @Test
      public void testAuthentication() {
        // 1、构建 securityManager(提供安全服务) 环境
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(simpleAccountRealm);
    
        // 2、主体 subject 提交认证请求
        SecurityUtils.setSecurityManager(defaultSecurityManager); // 配置环境
        Subject subject = SecurityUtils.getSubject();
        
        // 配置自定的token
        UsernamePasswordToken token = new UsernamePasswordToken("ch", "123");
        // 登录
        subject.login(token);
    
        System.out.println("isAuthenticated: " + subject.isAuthenticated());
    
        // 登出
        subject.logout();
        System.out.println("isAuthenticated: " + subject.isAuthenticated());
    
      }
    
    }

如果修改账号，则会报错：

如果修改密码，则会报错：
