信息: Servlet action is currently unavailable

Answer 1

getOutputStream() has already been called for this response 确定是spring配置文件出现的错误吗?设个断点debug下 先看错出在哪！

Answer 2

getOutputStream() has already been called for this response 确定是spring配置文件出现的错误吗?

Answer 3

这个错误和spring没关系，是你用了response.getOutputStream()才出的错。仔细看一下你的代码关于response.getOutputStream()的用法，哪块用错了

Answer 4

at AO.fire.filter.GBKFilter.doFilter(GBKFilter.java:29) 
检查下,是否在里面使用了spring也会加载的文件,造成重复加载

严重: Servlet.service() for servlet jsp threw exception 
java.lang.IllegalStateException: getOutputStream() has already been called for this response呵呵,大家都知道是这个错误了,所以建议楼主去看看包,还有配置文件,设置断点执行是相当管用的,因为如果你的程序能够跑起来,就可以看出使一些具体的问题了,

Answer 6

不是SPRING的问题, 是你SERVLET的问题, 好好查一下你的SERVLET吧
