Quickly understand shiro certification

shiro certification:

flow chart:

Quick Start mode using test cases:

Annotation sequence execution unit tests:

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

Test code:

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); 

        // Get the current theme application or the User 
        Subject Subject = SecurityUtils.getSubject (); 

        // username password 
        UsernamePasswordToken usernamePasswordToken = new new 
                UsernamePasswordToken ( "zbbiex", "456" ); 
        subject.login (usernamePasswordToken) ; 

        // Get an authentication result 
        Boolean RES = subject.isAuthenticated (); 

        System.out.println ( "authentication result is:" + RES); 

    } 
}
