很明显是端口冲突。但是我本地没起其他服务，不会有端口占用。

然后查是否真的端口被占用，

在开始-运行，输入CMD打开命令行界面，输入命令

netstat -ano | findstr "1099" 

查出来也是没有1099端口占用的情况。

然后一直百度查各种解决方案，大部分查出来都是怎样处理端口冲突：

一：更改服务器的端口号；

二：关闭占用当前端口的进程

我也尝试跟着百度提供的解决方案，找占用端口，修改端口，杀进程等待，但是没起作用都是报这个错误。

这时，我觉得不是其他程序端口占用的问题，应该tomcat配置有问题。

这有两个地方配置了“1099”。我试着把端口配置更大数据，还是报一样的异常。

最后怀疑是两个端口一致，起服务时候已经起了JMX1099端口，接着在起AJP1099,则冲突了。

试着把其中一个改为“1098”，再起服务，不报这个错了。

这个问题纠结一个下午，最终解决了。把整个解决过程写出来是为了后来者少踩点坑。
