Bluemix cloud foundry java应用程序异常：OutputStream已关闭

我使用SpringMVC的Java web应用程序在Tomcat中运行得很好，但在BluemixCloudFoundry上运行不好。在每个HTTP请求之后，日志中存在以下消息，并且在方法调用之后不会返回响应：

异常：OutputStream已关闭

有什么想法吗

如果您使用Tomcat在本地进行开发，那么应该在Bluemix油井上使用Tomcat。默认情况下，当您推送jar/war/ear时，将使用webspherelibertybuildpack。如果要使用Tomcat，请使用预安装的java_buildpack buildpack，如下所示：

cf push MyAppName -p target/myapp.war -b java_buildpack

如果您使用的是manifest.yml文件：

---
applications:
 - name: MyAppName
   path: target/myapp.war
   buildpack: java_buildpack

---

根据日志，当它试图显示错误页面时，似乎会发生这种情况。这意味着，除了最初的问题外，错误处理中还有一个问题。听起来像是-您有关闭响应输出流的servlet代码吗？@Henry在报告异常之前没有错误。Tnx@hugh不，我没有手动关闭输出流，我使用的是SpringMVC。Tnx
