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：
