I am trying to set up a break point in my controller so that I can debug my spring boot web application within spacemacs. Can someone walk me through the steps on doing this.
The steps I have done so far are
- start up the spring boot application in debug mode with the 8000 port as the debug port. I did this by adding to my pom the following.
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<jvmArguments>-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000</jvmArguments>
</configuration>
</plugin>
</plugins>
</build>
- execute the
mvn spring-boot:runcommand. I have added the entire command run below with the logs. It does show 8000 port listening M-x dap-debug- I select Java-Attach
- I enter
8000as the debug port
I have added an image of my controller that has breakpoints. One thing I notice is that in the bottom bar it shows localhost(8000) - pending. So it seems that dap does not attach to the debug port.
I am not sure if this is relevant to this issue, but I am currently spacemacs develop branch.
