		<groupId>org.slf4j</groupId>
		<artifactId>slf4j-log4j12</artifactId>
		<version>1.7.12</version>

log4j.rootLogger=INFO, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n

# General Apache libraries
log4j.logger.org.apache=WARN

# Spring

# Disable verbose logging
log4j.logger.org.apache.shiro.util.ThreadContext=WARN

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();
	}
}
