1. 修改Java程序的启动命令

修改dockerfile文件中的启动命令，重新部署服务到测试环境，记得在debug完成后，把这个参数再修改回来，不要带到线上环境

Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9997

2. 转发容器端口

本机需要安装kubectl工具-方法链接，配置rancher-cli工具-方法链接

edzdeMacBook-Pro:.kube edz$ rancher kubectl get pod

3. idea配置

最后一步最关键，需要保证服务端的代码和本地时一样的，请注意！
