Spring Boot Application fails after Debug is started

Question

I have a spring boot application which I have started for debug using command:

sudo mvnDebug spring-boot:run

The Spring app shows message:

Preparing to execute Maven in debug mode
Listening for transport dt_socket at address: 8000

Now, I start the debugging from eclipse attaching to listener at locahost:8000.

The Spring Boot application shows error now as below:

    17:26:20.747 initApplicationContext: this=com.xxx.platform.sp.spring.SpringApplicationContext@63c29d69 prev=null applicationContext=org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@738f69dd: startup date [Tue Oct 31 17:25:55 IST 2017]; parent: org.springframework.context.annotation.AnnotationConfigApplicationContext@76a02fc2  (cl=java.net.URLClassLoader@45bb3370)

I am unable to debug. Any help is appreciated.

hi Rajeev there are two ways you can debug spring boot app either through command prompt or through eclipse configurations.If you are using eclipse you can use DebugConfigurations->RemoteJavaApplication->Configure the port with locahost name and provide the port and debug if you are using command prompt it is different scenario. — Pradeep, Oct 31 '17 at 13:21
