调试独立的Spring Boot应用程序（Intellij IDEA）

Question

I am using Intellij IDEA 14.1 and I am trying to debug the most basic standalone Spring Boot 1.2.5 application. Would someone please tell me how to do that?

I've read http://docs.spring.io/autorepo/docs/spring-boot/1.2.5.RELEASE/maven-plugin/usage.html but have not been successful in making it work. The easiest would be to disable the forking that Spring Boot is using when debugging, but again, I was not successful in doing so. (-Dfork=false?)

Any help is much appreciated!

Answer 1

I am confused.

You have a main method that starts your standalone Spring Boot application, right? Well, right click on that and choose Debug 'YourApp'

Answer 2

The issue above did not require anything specific related to Spring Boot . I have found that there was an issue in the error log of the IDE saying can't proxy final class class com.sun.tools.jdi.ClassTypeImpl which was related to an outdated JRebel plugin I had installed in my IDE. The issue was then resolved by updating the outdated JRebel plugin. Afterwards, it is the usual process as if you were debugging any other application

Answer 3

When you create a new remote configuration in IntelliJ it gives you the command line arguments for remote debugging.

• open edit configurations
• add new remote configuration
• Now the configuration tab on the right lists the Java command line arguments for running the jar in debug mode.

For example, start your Spring Boot application with:

java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8008 -jar yourapplication.jar

Then select the debug icon to enable your breakpoints.
