Demo的目录结构：

1、创建一个Maven Project

在pom.xml添加依赖包，如果你不知道shiro要添加那些包，可以点击http://www.mvnrepository.com/，输入shiro，即可查到相应的包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>org.shiro.test</groupId>  <artifactId>testShiro</artifactId>  <version>0.0.1-SNAPSHOT</version>  <name>testShiro</name>    <dependencies>  <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>1.7.19</version></dependency>  </dependencies></project>

2、在src/main/resource中，创建一个shiro.ini 配置文件，添加相应的用户，这里是以键值对的方式（账号=密码）

[users]root=123456user=user

3、创建log4j.properties 日志文件

4.在src/main/java，创建一个测试类

public class TestShiro {public static void main(String[] args) {//读取配置文件，初始化SeurityManager工厂Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");//获取SecurityManager实例SecurityManager sm = factory.getInstance();//把securityManager实例绑定到SecurityUtils中    SecurityUtils.setSecurityManager(sm);    //获取当前用户    Subject currentUser = SecurityUtils.getSubject();    //令牌    UsernamePasswordToken token = new UsernamePasswordToken("root", "123456");    try{    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();}}

运行结果：在控制台打印出身份认证成功！

当然如果你账号密码错误，就打印出身份认证失败！
