    在网络上有一个很多人转载的springmvc+redis整合的案例,不过一直不完整,也是被各种人装来转去,现在基本将该框架搭建起来。

    package com.pudp.bae.base; import java.io.Serializable; public abstract class BaseModel implements Serializable{ } package com.pudp.bae.base; import java.util.Map; import org.springframework.web.servlet.ModelAndView; public class BaseMultiController { protected ModelAndView toView(final String url,final Map<String,Object> map) { ModelAndView view = new ModelAndView(url); return view; } }
