1. 流没关闭。
2. 未设置响应头。
3. jsp页面需要清空流。说一下我们遇到的情况。就是一个简单的sprinboot项目。

在用httpclient请求项目接口会报以下的错误。
1. Forwarding to error page from request [/xxx/xxx] due to exception [getOutputStream() has already been called for this response]接口项目报这个错
2. java.io.FileNotFoundException: http://1xxx/xxx/xxx/xxxhttpclient项目报这个错
信息如下(接口项目):

org.junit.runners.ParentRunner.access$000(ParentRunner.java:58)问题猜想
1. springboot项目配置了thymeleaf模板由于404请求跳转error.html。
2. 由于没有error.html导致客户端变成了file找不到。
3. 花生壳映射问题在服务器好像是没有问题证明代码没有问题。
解决方式
1. 检查请求是否404。
2. 关闭thymeleaf的配置。
3. 不要用花生壳。在服务器上如果还出现类似问题可能就是代码的问题了。
