• Hello Shiro


    【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 Shiroshiro-root-1.2.3-source-releaseshiro-root-1.2.3samplesquickstartsrcmain esources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 Shiroshiro-root-1.2.3-source-releaseshiro-root-1.2.3samplesquickstartsrcmainjava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

    附:

    Quickstart.java:

      1 package com.hk.shiro.hello;
