解决java启动时报线程占用报错：Exceptioninthread“Threa

前言

　　本文提供三种不同的解决方式，也是三种不同的情况和思路

　　我的问题是在springboot整合了xxl-job一段时间后出现的。如果你程序里集成了xxl-job或者有需要配置端口的地方，这篇文章或许可以给你带来启发或者解决你的问题。

1 异常

　　启动项目后抛出异常，但是奇怪的是执行器在任务调度中心中注册成功，也能成功执行

2 问题定位

2.1 第一种情况

　　网上有的说通过

　　在低版本的 xxl-job 中，初始化XxlJobSpringExecutor执行器需要在@Bean中加上 initMethod = start, destroyMethod = destroy，但是在高版本的 xxl-job（如 2.1.2）则需要删除 initMethod = start, destroyMethod = destroy

　　而我的问题不是在bean上加(initMethod = “start”, destroyMethod = “destroy”。
