• shiro示例讲解


            官网shiro例子,可以很好的帮助我们理解和运用shiro。下面就讲解下怎么如何使用maven来运行官网示例,及理解其实现过程。

            一、新建maven项目

          new->other->Maven project->Create a simple project (勾选)

           

       二、新建shiro文件(shiro.ini),放入src/main/resources路径下,log4j.properties也是放入该路径下。

            

     1 # =============================================================================
     2 # Tutorial INI configuration
     3 #
     4 # Usernames/passwords are based on the classic Mel Brooks' film "Spaceballs" :)
     5 # =============================================================================
     6 
     7 # -----------------------------------------------------------------------------
     8 # Users and their (optional) assigned roles
     9 # username = password, role1, role2, ..., roleN
    10 # -----------------------------------------------------------------------------
    11 [users]
    12 root = secret, admin
    13 guest = guest, guest
    14 presidentskroob = 12345, president
    15 darkhelmet = ludicrousspeed, darklord, schwartz
    16 lonestarr = vespa, goodguy, schwartz
    17 
    18 # -----------------------------------------------------------------------------
    19 # Roles with assigned permissions
    20 # roleName = perm1, perm2, ..., permN
    21 # -----------------------------------------------------------------------------
    22 [roles]
    23 admin = *
    24 schwartz = lightsaber:*
    25 goodguy = winnebago:drive:eagle5

     三、pom.xml文件配置

           1、引入shiro的相关jar包,shiro依赖slf4j包,这里也可引入下。

             

            

                注意:shiro-core 高版本的jar包,已经不支持读取配置文件这种方式了。项目中低版本1.2.4的是支持的。

           2、要执行main函数,这里引入maven-compiler-plugin插件和exec-maven-plugin插件。其中exec-maven-plugin插件配置中需指定执行main函数所在类的路径

              

         具体pom.xml配置参考如下:

    五、eclipse执行shiro示例项目配置

      

    重要提示:pom.xml配置文件中引入依赖的jar版本,及更新新的jar包版本号,可到中央仓库查询。
