学习shiro——简单的hello world实现

摘要: 跟着视频学习shiro,视频地址：http://www.java1234.com/a/yuanchuang/shiro/2015/1102/5171.html，学习并记录

1.pom.xml文件：

2.配置文件：shiro.ini

[users]
jack1234=1234
hello =123

3.配置文件log4j.properties

# LOG4J配置
log4j.rootLogger=debug,stdout

### 把日志信息输出到控制台 ###
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

4.HelloWorld.java文件

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;

/**
* Created by guanguan on 17/6/12.
*/
public class HelloWorld {
public static void main(String[] args) {
//读配置文件,初始化SecurityManager
Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.properties");

//获取SecurityManager实例
SecurityManager securityManager = factory.getInstance();

//把SecurityManager实例绑定到SecurityUtils
SecurityUtils.setSecurityManager(securityManager);

//获取当前登录的用户
Subject currentUser = SecurityUtils.getSubject();

//构建token令牌。用户名/密码
UsernamePasswordToken token = new UsernamePasswordToken("jack1234", "1234");
try {

//身份认证
currentUser.login(token);
System.out.println("登录成功");
} catch (AuthenticationException e) {
e.printStackTrace();
System.out.println("登录失败");
}

}
}

以上为shiro的基本简单案例。
