此类报错首次接触，在阅览一些文章后，总结如下：
pipe是管道的意思，管道里面是数据流，通常是从文件或网络套接字读取的数据。
当该管道从另一端突然关闭时，会发生数据突然中断，即是broken。
对于文件File来说，这可能是文件安装在已断开连接的光盘或远程网络上。
对于socket来说，可能是网络被拔出或另一端的进程崩溃。
在Java中，没有具体的BrokenPipeException。
将此类错误包含在另一个异常，例如java.io.IOException:Broken pipe
一、Broken pipe产生原因分析
1.当访问某个服务突然服务器挂了，就会产生Broken pipe;
2.客户端读取超时关闭了连接，这时服务器往客户端再写数据就发生了broken pipe异常！
在发生报错时，整个项目服务并没有出现其他问题，所以错误原因也只能是第二种情况，发生此情况时，前端调用接口查询了数据库约5000数据，数据返回前端延时也不算特别大，前端也是做了超时时间限制，但数据返回延时并未达到前端预设超时时间，也可能是当时发送错误那次前端请求确实超时造成，使用jmeter进行压力测试并没有出现此类型报错信息，但是压力测试发现小部分数据响应达到了7s的延时问题，而前端接收响应超时为5s，随即进行代码优化，目前响应大概400ms，暂未出现此类问题

三、处理方案
1.可以查看下前端接收响应时间是否存在限制，有可能是前端设置了接收响应时间从而断开了连接造成此类报错。
2.使用jmeter等测试工具检查下接口响应情况，能对代码进行优化的就优化。
