第一节：Shiro HelloWorld 实现

1、新建maven工程，pom配置maven jar包

<dependency>		<groupId>org.apache.shiro</groupId>		<artifactId>shiro-core</artifactId>		<version>1.2.4</version>    </dependency>        <dependency>		<groupId>org.slf4j</groupId>		<artifactId>slf4j-log4j12</artifactId>		<version>1.7.12</version>	</dependency>

2.resourses下新建文件配置shiro.ini，配置如下

[users]java1234=123456jack=123

3.resourses下新建文件配置log4g.properties，配置如下

3.新建class文件HelleWorld.java

?package com.slix.shiro;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.AuthenticationException;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;public class HelleWorld {	public static void main(String[] args) {		// 读取配置文件，初始化SecurityManager工厂		Factory<SecurityManager> factory=new IniSecurityManagerFactory("classpath:shiro.ini");		// 获取securityManager实例		SecurityManager securityManager=factory.getInstance();		// 把securityManager实例绑定到SecurityUtils		SecurityUtils.setSecurityManager(securityManager);		// 得到当前执行的用户		Subject currentUser=SecurityUtils.getSubject();		// 创建token令牌，用户名/密码		UsernamePasswordToken token=new UsernamePasswordToken("java1234", "123456");		try{			// 身份认证			currentUser.login(token);				System.out.println("身份认证成功！");		}catch(AuthenticationException e){			e.printStackTrace();			System.out.println("身份认证失败！");		}		// 退出		currentUser.logout();	}}
