解决Java中的java.io.IOException：Brokenpipe问题
Java 中java.io.IOException: Broken pipe
认识broken pipe
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
解决问题
其实当该异常产⽣的时候，对于服务端来说，并没有多少影响。因为可能是某个客户端突然中⽌了进程导致了该错误。但是为了程序能够美观、优雅，还是要在合适的地⽅捕获该异常，并处理⼀下。
还有⼀种可能性就是程序⾥⾯有代码执⾏时间过长，⽤户等待时间过久，才会强⾏中⽌进程。
无形资产减值准备
那么这种情况下就需要去分析log中报异常的地⽅是经常发⽣在什么地⽅，合理优化该段代码，提升代码的运⾏速度，才能从根本上避免此类问题的再次发⽣。
可能原因：
1、客户端请求服务器数据，服务器突然挂了；
2、客户端请求服务端数据，服务端正常返回，凡是客户端由于超时等原因断开。
原因分析：
做了压⼒测试，发现遇到的情况属于第⼆种，由于去数据库取数据的时候，30秒⾥⽆法正常获取有效的数据库连接，或者查询时间长，导致OSB过来的请求超时，也就是客户端超时了，服务端还试图返
回数据，结果导致如题异常。
解决⽅法：
甜酒的制作过程
1、增⼤数据库连接池数量；
2、延长客户端超时时间。
java.io.IOException: Broken pipe 线上问题记录
肯德基代言人今天在上线前staging环境验证时遇到这样⼀个问题java.io.IOException: Broken pipe，操作服务刚起来之后，测试⼈员第⼀次进⾏更配[post]操作，结果操作失败，但是第⼆次就好了，
我们是springboot+angularJs前后端分离，然后服务使⽤k8s在容器中部署，原始的异常栈信息是这样，

之后的操作，就正常了，正常⽇志如下：
夜深了
google之后⼤概知道是什么问题了
注：读懂下⾯这句话，⾸先要熟悉TCP 四次挥⼿，不太熟悉请右转google
总结 Broken Pipe：
这个异常是客户端读取超时关闭了连接，这时候服务器端再向客户端已经断开的连接写数据时就发⽣了broken pipe异常！
作为⼀个后端⼯程师，⼀定要对⽇常的⼀些异常有⼀个积累总结，笔者就⾃⼰有在总结，⼀是总结整理之后，下次遇到同样的问题⾃⼰不会很茫然不知所措，尤其是在上线是，其他同事都在等着你解决问题的时候，你吭吭唧唧那就不太好了，⼆是笔者之前在⾯试时也有经常被问到类似的问题，记忆尤新的就是被云校的百度⼩哥问到connection by peer，之前博客也有介绍，作为社招有经验的⼯程师，更不能再以校招的⾯试作为⾃⼰的标准了，要有⾃⼰的经验积累，反正就是，⼲，就完了
最后，附⼀张我的错误记事本截图
以上为个⼈经验，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。
