ehcache换成redis有很多问题~

yinkai

1. 按照官方帮助文档修改有以下问题

ehcache指定key清空缓存，Redis没有提供相同方法



Redis没有提供TagCache这个元素。

官网一笔带过 这种问题 要如何解决~~

算了 我自己顶一下吧 简单看了看代码 应该是 这部分代码 漏写了吧

把ehcache换成redis后，项目启动发生空指针异常
启动后输入密码点击登录 ，会调用如下图方法

这是 进入到切面方法如下图

在argTypes=arguments.getClass(); 这行发生了空指针
DEBUG各内容如下：
targetName    =  class org.jeecgframework.web.system.service.impl.SystemServiceImpl
methodName =  loginUserIsHasMenuAuth
arguments     =  [loginController.do?hplushome, null, 8a8ab0b246dc81120146dc8181950052, 8a8ab0b246dc81120146dc8180ba0017]

根据参数内容 当循环第二次的时候 会发生空指针异常。  
异常信息如下：

下个版本会大重构，着急的话，可以先自己改造
