This article is to share with you about the SpringBootDebug debugging process, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it.

Recently found that Spring Boot can not debug Debug locally, the original Spring Boot upgrade, the corresponding plug-in command parameters have changed, so this article makes an upgrade.

Background:

When the Spring Boot project executes the startup command spring-boot:run using the Spring Boot Maven plug-in, if the breakpoint cannot be entered, the following settings should be made.

Official solution:

By default, the run goal runs your application in a forked process. If you need to debug it, you should add the necessary JVM arguments to enable remote debugging. The following configuration suspend the process until a debugger has joined on port 5005:

Let's just see what to do!

1. Add JVM parameters

Add jvmArguments configuration to the plug-in spring-boot-maven-plugin.

......... Org.springframework.boot spring-boot-maven-plugin 2.2.0.RELEASE-Xdebug-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005...

Or specify on the command line:

Mvn spring-boot:run-Dspring-boot.run.jvmArguments= "- Xdebug-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"

For the latest configuration, please refer to the official instructions:

Https://docs.spring.io/spring-boot/docs/current/maven-plugin/examples/run-debug.html

2. Add a Remote

Add a Remote configuration to the development tool:

You only need to determine the Host and Port parameters.

Host: address

Localhost: local boot address

Port: Port

5005: the port specified on the command line above

3. Start debugging

Start the Spring Boot project with the jvmArguments parameter first:

The program stops at the listening port: 5005, and then debug starts Remote:

Go back to the project, start the output log, and then you can do breakpoint debugging.

This is remote debugging, can also help you debug remote Spring Boot application, but in local debugging to operate twice, slightly troublesome.

The above is what the SpringBootDebug debugging process is like, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
