本文探讨了在处理ActionForward对象与response之间的冲突时，将action中的returnSUCCESS更改为returnnull的有效策略。

每个方法都返回的是一个ActionForward对象，而response是ActionForward对象参数，所以就会使response冲突！

把action里的最后 “return SUCCESS ” 改成了 “return null ”

最近在捣鼓SpringMVC的文件下载服务，使用到了ResposeEntity来处理下载服务，需要返回响应实体，而要下载的文件则需要转为对应的流然后连同响应实体一起返回出去。然后我又重新捣鼓了java平常的下载处理方式，在SpringMVC的环境下使用了原生HttpServletRespose的对象来获取输出流，最后页成功的传输了下载了文件，但是却爆出了这个异常。说我已经调用过getOutputStream()这个方法了，也就是说重复调用了。虽然无伤大雅，但是看着还是不舒服。于是便查询了一下报这个异常的原因
