Input: mvn clean package
, (probably required Wait a few minutes), it is best to specify the local repository before building, so there is no need to re-download the jar package.
Specify socket port = 8081 and specify the port to be debugged Module
a. First start debug in IDEA
#b. Then enter the command in the terminal: java -agentlib:jdwp=transport=dt_socket,server=n,address=localhost:8081 -jar remote_test-0.0. 1-SNAPSHOT-all.jar
Mark breakpoint on the interface preparing the request
Note: You must start Debug in IDEA first, and then start the project
