Shiro起步

1、测试环境  IntelliJ Idea

2、pom配置

3、代码

package com.mracale;

import static org.junit.Assert.assertTrue;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;
import org.junit.Test;

/**
 * Unit test for simple App.
 */
public class AppTest 
{
    @Test
    public void Test(){
        //1、创建SecurityManager工厂对象：加载配置文件，创建工厂对象
        Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
        //2、通过工厂对象，创建SecurityManager对象
        SecurityManager securityManager = factory.getInstance();
        //3、将securityManager绑定到当前运行环境中，让系统随时随地可以访问securityManager对象
        SecurityUtils.setSecurityManager(securityManager);
        //4、创建当前登录的主体，注意：此时主体没有进过认证
        Subject subject = SecurityUtils.getSubject();
        //5、收集主体登录的身份/凭证，即账号密码
        UsernamePasswordToken token = new UsernamePasswordToken("test1","111");
        //6、主体登录
        try{
            subject.login(token);
        }catch (Exception e){
            //e.printStackTrace();
        }
        //7、判断是否登录成功
        System.out.println("验证登录是否成功"+subject.isAuthenticated());
        //8、退出登录
        subject.logout();
        System.out.println("验证登录是否成功"+subject.isAuthenticated());

    }
}
