configuring HTTP endpoint to shutdown a spring boot web application

Question

I have a Spring boot application running. Referring https://stackoverflow.com/a/36275797/6038386 to gracefully shut down the server, I included all changes in my pom.xml and application.properties.

Problem is when I am running spring boot server on one terminal (It starts successfully as expected) and try to shut it down using command: curl -X POST localhost:8000/shutdown on another terminal, server still keeps running. It is not shutting down. On my local, I don't see any logs or exception when i hit this shutdown command.

**

Can someone please help me to figure out, what is missing in my configuration.

**

Note: When I tried to shut down the server using Jenkins job having same command (and running jenkins server had same pom and properties as my local), i got following exception: {"timestamp":1515145896307,"status":500,"error":"Internal Server Error","exception":"java.lang.NoClassDefFoundError","message":"org/springframework/boot/actuate/endpoint/ShutdownEndpoint$1","path":"/shutdown"}

My pom.xml is as follows:

my application.properties includes following lines:

server.port=8000
endpoints.shutdown.sensitive=false
endpoints.shutdown.enabled=true

With the 1.5 version of spring boot , i think there is no sure shutdown mechanism.

You can see check this link and follow how to properly shutdown with jmx or http, https://github.com/corentin59/spring-boot-graceful-shutdown in your application.

good Luck

:No, actually I have another project with version 1.5.9 - and normal shutdown mechanism mentioned in https://stackoverflow.com/a/36275797/6038386 works fine there. Looks like there is something else going wrong in code here. – Naveen Kumar Jan 06 '18 at 17:34

Answering my own question:

Actually it was a silly mistake. I was just copy pasting the stuff from https://stackoverflow.com/a/36275797/6038386 without actually understanding it.

I had included server.contextPath=/AllergiesConditions in my application.properties

So now command to shutdown would become: curl -X POST localhost:8080/AllergiesConditions/shutdown

Another mistake I did was that, I didn't post my full application.properties in question's description, so actually no one could help.
