java.io.IOException: Broken pipe 异常处理

by

java.io.IOException: Broken pipe at sun.nio.ch.FileDispatcherImpl.writev0(Native Method) at sun.nio.ch.SocketDispatcher.writev(SocketDispatcher.java:51)

出现这种问题，一般有以下几种情况

  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，服务端返回正常。但客户端由于连接超时或者其他原因断开导致服务端无法返回通道导致

通过traceid找到这个异常导致的下一个异常

java.io.IOException: UT010029: Stream is closed
at io.undertow.servlet.spec.ServletOutputStreamImpl.write(ServletOutputStreamImpl.java:138)

这个就很明显了是第二中情况，客户端问题导致了Stream is closed

这种Jpa的错误查找错误出处，错误详情如下

ERROR [12:01:12.102] [1da1d72f575b4f95af5e0cdde8b114e1] [192847] [1] [] [100] [2.28.1] [o.h.e.jdbc.spi.SqlExceptionHelper – logExceptions – 142] – Table ‘tp.video’ doesn’t exist

org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet

重点：

ERROR [12:01:12.102] [1da1d72f575b4f95af5e0cdde8b114e1] [192847] [1] [] [100] [2.28.1] [o.h.e.jdbc.spi.SqlExceptionHelper – logExceptions – 142] – Table ‘tp.video’ doesn’t exist

有的时候是字段对不上，有的时候是表不存在，直接创建即可

刚开始以为是bean加载不了，看下Idea语法也没有报错，网上找了一波 Spring boot2.x + Elasticsearch7.x 才想起引入了分词依赖

可能有比较老的jar包冲突了。查了一下文档，发现lucene-core未引入，果断引入解决问题
