[点击进入Shiro 下载官网][Shiro]

1、所需jar包

shiro-all-1.4.1.jar、log4j-1.2.17.jar、slf4j-api-1.7.28.jar、slf4j-log4j12-1.7.28.jar

2、导入以下两个文件（文件位于shiro-root-source-release\\shiro-root\\samples\\quickstart\\src\\main\\resources文件夹下）

3、Quickstart.java代码

package com.hern.shiro;
    
    import org.apache.shiro.SecurityUtils;
    import org.apache.shiro.authc.*;
    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 Quickstart {
    
        private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);
    
    
        public static void main(String[] args) {
            //创建Shiro SecurityManager的最简单方法
            //领域、用户、角色和权限是使用简单的ini配置。
            //我们将使用一个可以接收.ini文件
            //返回SecurityManager实例：
            //使用类路径根目录下的shiro.ini文件
            //（file:和url:分别从文件和url加载前缀）：
            Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
            SecurityManager securityManager = factory.getInstance();
    
            // for this simple example quickstart, make the SecurityManager
            // accessible as a JVM singleton.  Most applications wouldn't do this
            // and instead rely on their container configuration or web.xml for
            // webapps.  That is outside the scope of this simple quickstart, so
            // we'll just do the bare minimum so you can continue to get a feel
            // for things.
            SecurityUtils.setSecurityManager(securityManager);
    
            //获取当前正在执行的用户：
            //获取当前的Subject，调用SecurityUtils.getSubject();
            Subject currentUser = SecurityUtils.getSubject();
    
            //在会话中做一些事情（不需要Web或EJB容器！！！！）
            //测试使用Session。首先获取Session,通过Subject的getSession()
            Session session = currentUser.getSession();
            session.setAttribute("someKey", "aValue");
            String value = (String) session.getAttribute("someKey");

            }
    
            //让我们登录当前用户，以便检查角色和权限：
            //测试当前的用户是否已经被认证，即是否已经登录
            //调用Subject的isAuthenticated()
