我遇到了一个问题，我无法在IntelliJ中调试maven sprint启动REST API应用程序 . 应用程序启动但不会在任何断点处停止 .
另外，当我停止调试器时，我在日志中看到下面的行，但我可以看到java进程永远不会终止，当我第二次启动应用程序失败时，因为服务器端口8080仍在使用中 .
Disconnected from the target VM, address: '127.0.0.1:53020', transport: 'socket'
Process finished with exit code -1
在C：\ Users \ Bernhard.IdeaIC2017.3 \ system \ log的IntelliJ日志中，我看到以下错误 .

您可以将该参数的值包装在引号中 . 读取整个命令行字符串的解析器可能因为-D arg中的-D arg而窒息 .
clean包-Drun.profiles = dev-us-east-1 -Drun.jvmArguments = "-Denvironment=dev" -DskipTests spring-boot：run
经过一些搜索后，我发现问题出在IntelliJ中的Maven Run / Debug配置中 . 我用来启动spring boot rest api的命令行是
看来
-Drun.jvmArguments=-Denvironment=devjava命令行属性是罪魁祸首 . 当我删除它时，断点再次起作用 .
