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=123456
jack=123

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

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
log4j.logger.org.springframework=warn

# default shiro logging
log4j.logger.org.apache.shiro=trace

# disable verbose logging
log4j.logger.org.apache.shiro.util.threadcontext=warn
log4j.logger.org.apache.shiro.cache.ehcache.ehcache=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();
	}
}
