Shiro认证

认证过程

• 1、创建SecurityManager
• 2、主体提交认证
• 3、SecurityManager认证
• 4、Authenticator认证
• 5、Realm验证

代码演示

• 1、引入shiro依赖

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-core</artifactId>
    <version>1.4.0</version>
</dependency>

• 2、创建AuthenticationTest测试类

public class AuthenticationTest {
    SimpleAccountRealm simpleAccountRealm = new SimpleAccountRealm();
    @Before
    public void addUser() {
        simpleAccountRealm.addAccount("Mark", "123456");
    }

    @Test
    public void testAuthentication() {
        // 1. 构建SecurityManager环境
        DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
        defaultSecurityManager.setRealm(simpleAccountRealm);

        // 2. 主体提交认证请求
        SecurityUtils.setSecurityManager(defaultSecurityManager);
        Subject subject = SecurityUtils.getSubject();

        UsernamePasswordToken token = new UsernamePasswordToken("Mark", "123456");
        subject.login(token);

        System.out.println("isAuthenticated:" + subject.isAuthenticated());

        subject.logout();

        System.out.println("isAuthenticated:" + subject.isAuthenticated());
    }

}
