# Idea编译器热部署时报错 1099 端口占用（Application Server was not connected before run configuration stop, reason:）    #

idea的热部署功能基于插件 JRebel，具体可以看    [这里][Link 1]

## 首先，检查端口是否被占用    ##

不用什么CMD之类的，过于繁琐，直接更改Idea 的tomcat启动端口，随便更改两三次，大于1000即可，(大部分端口都未使用)；可以就OK，不行就接着看。

当然更鼓励使用命令行检查（学习新东西肯定至少不是太坏的事情）。

## 检查JRE ##

如果没有JRE，或者没有配置JAVA环境的，建议先去找一个JAVA入门视频和书籍。

有JRE并且环境正确，请将这里的 默认 或 1.x  更改为jre配置环境的路径![Center][]

如果还是不行，引用这篇博客的观点：[点击打开链接][Link 2]

#### 3.如果还没有解决，我建议你看一下tomcat的bin目录下的setclasspath.bat文件，看一下下面加粗的两行是不是还是不对，如果不对的话，改一下，就可以运行了 ####
