SAP Cloud Foundry中的远程调试 [英] Remote Debugging in SAP Cloud Foundry

问题描述

我想知道如何远程调试部署在SAP Cloud Foundry中的S4SDK/Spring 2.0.6 Java应用程序.

I am wondering how to remote debug a S4SDK/Spring 2.0.6 Java Application deployed in SAP Cloud Foundry.

我正在使用Eclipse(Spring工具套件)，并在调试模式"下启动了该应用程序.应用程序将使用以下环境变量重新启动:-Dspring.devtools.remote.secret = secret -Xdebug -Xrunjdwp:server = y，transport = dt_socket，suspend = n，address = 47822

I am using Eclipse (Spring Tool Suite) and started the app in Debug Mode. The application will be restarted with the following environment variable: -Dspring.devtools.remote.secret=secret -Xdebug -Xrunjdwp:server=y,transport=dt_socket,suspend=n,address=47822

控制台输出显示，启动后会自动成功创建SSH隧道(作为前提条件，我已使用cf enable-ssh启用了SSH).和成功通过10.0.136.5:34858进行远程访问".

The console output shows, that after startup an SSH tunnel has automatically been created successfully (as a prerequisite I have enabled SSH using cf enable-ssh). and 'Successful remote access by 10.0.136.5:34858'.

几秒钟后，eclipse显示消息无法连接到远程VM".

After a few seconds, eclipse shows the message "Failed to connect to remote VM".

如何启用远程调试?

推荐答案

这取决于您使用的buildpack(请参阅

This depends a bit on the buildpack you are using (see this link).

对于sap_java_buildpack，您需要执行以下操作:

For the sap_java_buildpack you need to do the following:

1. 在CF容器中运行jvmmon:

cf ssh <app name> -c "app/META-INF/.sap_java_buildpack/sapjvm/bin/jvmmon"

在打开的CLI中输入start debugging.

(可选)输入print debugging information以确认已启用调试.

(Optional) Enter print debugging information to verify that debugging is enabled.

使用q退出CLI.

要打开ssh隧道，请输入cf ssh <app name> -N -T -L 8000:127.0.0.1:8000.

To open the ssh tunnel enter cf ssh <app name> -N -T -L 8000:127.0.0.1:8000.

因此，您可以使用IDE的常规方法通过localhost:8000连接到您的应用程序.

With that you can connect to your application via localhost:8000 by the usual means of your IDE.

由于我没有在Eclipse中进行远程调试的经验，因此我无法为您提供帮助，在IDEA中，有一个特殊的远程"配置，您可以在其中添加远程URL，因此在这种情况下为localhost:8000.

As I have no experience with remote debugging in Eclipse I cannot help you with that part, in IDEA there is a special "Remote" Configuration where you can add the remote URL, so localhost:8000 in this case.
