【HelloWorld Shiro】
1.搭建开发环境-加入jar包
2.步骤（前提:已下载好Shiro资源包）：
①找到shiro-root-1.2.3-source-release包，
②按Apache Shiro\shiro-root-1.2.3-source-release\shiro-root-1.2.3\samples\quickstart\src\main\resources路径找到，将log4j.properties，shiro.ini文件加入到类路径（src）下,
③创建一个包，将Apache Shiro\shiro-root-1.2.3-source-release\shiro-root-1.2.3\samples\quickstart\src\main\java下的Quickstart.java文件放入包中。（注意：在该java代码中要添加包名代码）
3.运行结果：一大堆东西
