XxlJobRemotingUtil : Read timed out 解决

Spring cloud 整合的 XxlJob

生产环境日志信息里面包含大量重复的Read timed out错误信息

从错误信息中能看出来xxl-job的 [注册线程]报连接超时错误

原因是xxl-job注册失败,没有叫做baqianyi的key

xxl-job registry fail, registryParam:RegistryParam{registryGroup='EXECUTOR', registryKey='baqianyi', registryValue='http://xx.xxx.xxx.76:9999/'}, registryResult:ReturnT [code=500, msg=xxl-rpc remoting error(Read timed out), for url : http://cloud-xxl-job:8080/xxl-job-admin/api/registry, content=null]

经过排查，我发现我当前的项目并没有使用xxl-job的功能，但是引用了他的依赖和xxl-job.yaml，导致它会不断的请求注册。

xxl-job配置文件如下

xxl-job:
  port: 9999
  admin-addresses: http://cloud-xxl-job:8080/xxl-job-admin
  app-name: ${spring.application.name}
  log-path: /root/log/xxl-job/

解决方案

一、移除pom依赖

<!--        <dependency>-->
<!--            <groupId>com.htlm.common</groupId>-->
<!--            <artifactId>htlm-common-xxl-job</artifactId>-->
<!--            <version>1.0-SNAPSHOT</version>-->
<!--        </dependency>-->

二、移除nacos配置的引用

spring:
  profiles:
    active: dev
  application:
    name: baqianyi
  cloud:
    nacos:
      discovery:
        server-addr: ${NACOS_IP}:8848
      config:
        server-addr: ${NACOS_IP}:8848
        file-extension: yaml
        extension-configs:
          - data-id: common-${spring.profiles.active}.yaml
            refresh: true
          - data-id: redis-${spring.profiles.active}.yaml
            refresh: true
          - data-id: stream-${spring.profiles.active}.yaml
            refresh: true
#       移除nacos关联的配置                
#          - data-id: xxl-job-${spring.profiles.active}.yaml
#            refresh: true

总结

具体的错误出现的原因是因为，新的服务在搭建的时候，常常会在其他服务中复制粘贴配置文件过来，然而复制过来的配置文件就草草的改一下application应用名就了事了，从而引发一些bug。
