本文介绍如何在JavaSE环境下使用Eclipse搭建Shiro框架，包括创建项目、配置必要的Jar包、设置配置文件及编写核心代码。通过具体实例展示Shiro的使用流程，帮助初学者快速上手。

JavaSE环境下搭建Shiro

1、在eclipse环境下，点击file，新建一个Java project，右键点击项目新建一个lib目录用来存储shiro需要的jar包：

2、右键点击src新建一个com.shiro.exercise包，创建一个LoginAuthen类，并导入两个配置文件：

补：配置文件的导入可以自行在GitHub上下载相对应shiro的示例源码：https://github.com/apache/shiro或者在Apache官网上下载：http://www.apache.org/dyn/closer.cgi/shiro/1.3.2/shiro-root-1.3.2-source-release.zip

下载好后，解压，点击shiro-master->shiro-master->samples->quickstart->src->main->resources，将上面的两个配置文件log4j.properties和shiro.ini拷贝到你项目中src的目录下。

3、编写LoginAuthen类代码：

package com.shiro.exercies;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class LoginAuthen {
	private static final Logger logger = LoggerFactory.getLogger(LoginAuthen.class);
	
	public static void main(String[] args) {
		logger.info("我正在用log4j...");
		
		
		//获取安全管理器
		Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
		SecurityManager securityManager = factory.getInstance();
		
		//设置安全管理器
		SecurityUtils.setSecurityManager(securityManager);

		//获取当前用户
		Subject currentUser = SecurityUtils.getSubject();
		
		//获取当前用户session
		Session session = currentUser.getSession();
		
		session.setAttribute("name", "mingo");
		
		String name = (String) session.getAttribute("name");
		
		if(name!=null) {
			logger.info("shiro获取到的当前用户姓名为："+name);
		}
		
	}
}

4、控制台的运行效果：
