快速理解shiro的认证

shiro的认证：

流程图：

采用测试用例的方式快速开始：

单元测试注解的执行顺序：

@BeforeClass -> @before -> @Test ->@After ->@AfterClass

测试代码：

public class IsSpringbootShiroApplicationTests {
    private DefaultSecurityManager defaultSecurityManager = new
            DefaultSecurityManager();
    private SimpleAccountRealm realm = new SimpleAccountRealm();
    @Before
    public void init (){
        //初始化数据源
        realm.addAccount("woxbwo","123");
        realm.addAccount("zbbiex","456");

        //构建SecurityManager的执行环境
        defaultSecurityManager.setRealm(realm);
    }

    @Test
    public void testAuthentication() {
        SecurityUtils.setSecurityManager(defaultSecurityManager);

        //获取当前主题 application 或者 user
        Subject subject = SecurityUtils.getSubject();

        //用户名密码
        UsernamePasswordToken usernamePasswordToken = new
                UsernamePasswordToken("zbbiex","456");
        subject.login(usernamePasswordToken);

        //获取认证结果
        boolean res = subject.isAuthenticated();

        System.out.println("认证结果为:"+res);

    }
}

测试结果：
