Shiro学习总结（二）--Shiro的入门小例子

前文提到shiro的一些概念，接下来开始shiro的实际操作：
Shiro的入门小例子:
第一步：配置jar包，这里采用maven的方式，故pom.xml的配置文件如下：

<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>1.7.12</version>

</dependency>

第二步：暂时没有连接数据库，故采用静态数据，需要配置shiro.ini的文件模拟静态数据【user】表示用户，前面表示用户名

后面表示用户密码。

[users]

taojian=123456

jack=123

第三步：创建log4j的属性文件，这个日志管理。

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


第四步：编写关键的java代码;

package com.shiro.hello;


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("taojian", "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();

}

}
