Shiro自定义Ream

1. 项目目录结构
   
   2.代码：

package com.sun.shiro;

import org.apache.commons.lang3.StringUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.realm.Realm;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
 * 自定义realm的实现
 * @author suntan
 * @dade 2017年3月3日下午7:27:42
 * @version v1.0
 */
public class MyRealmDemo1 implements Realm{

    /**
     * 日志
     */
    private Logger logger = LoggerFactory.getLogger(MyRealmDemo1.class);

    public String getName() {

        return "myReamDemo1";
    }

    public boolean supports(AuthenticationToken token) {

        return token instanceof UsernamePasswordToken;
    }

    public AuthenticationInfo getAuthenticationInfo(AuthenticationToken token)  throws AuthenticationException {
        //获取用户名和密码
        String userName = (String) token.getPrincipal();
        //String passWord = (String) token.getCredentials();
        String passWord = new String((char[])token.getCredentials());
        if(!StringUtils.equals(userName, "sunny")) {
            logger.info("=======>用户名错误");
            throw new UnknownAccountException();
        }
        if(!StringUtils.equals(passWord, "1127")) {
            logger.info("====>密码错误");
            throw new IncorrectCredentialsException();
        }

        //用户名密码都对
        return new SimpleAuthenticationInfo(userName, passWord, getName());
    }



}

3.测试代码

package com.sun.shiro;

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;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class MyRealmDemo1Test {

    /**
     * 日志
     */
    private Logger logger = LoggerFactory.getLogger(MyRealmDemo1Test.class);

    @Test
    public void testGetAuthenticationInfo() {
        //1.加载配置文件
        Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro_realm.ini");
        //2.实例化对象
        SecurityManager securityManager = factory.getInstance();
        //绑定
        SecurityUtils.setSecurityManager(securityManager);
        //的到当前用户
        Subject subject = SecurityUtils.getSubject();
        //根据用户名密码登陆
        UsernamePasswordToken token = new UsernamePasswordToken("sunny", "1127");
        try {
            logger.info("=======>执行登陆");
            subject.login(token);
            logger.info("=======>登陆成功");
        } catch (Exception e) {
            logger.error("========>登陆失败：" + e);
        }
        //登出
        subject.logout();


    }

}

执行结果：
