cant connect mysql databse using spring boot error HTTP Status 404 the requested resource is not available
Question
Below mentioned code is not fetching data with mysql database using spring boot with maven dependency.After hitting url it was not displaying any json data. Previously I was working with gradle and was able to connect with database and gives me json value. I have copied code from that to maven project, No error in code. Can anyone help me out where I am doing mistake? Please also let me know if any easy way to do the same to make code better as I am naive in this.
1) Running on server
Hitting Url ( http://localhost:8080/CheckListMavenWebThree ) throws error instead of giving json value.
Let you know this is maven Dynamic web project
Error - Displays this on browser HTTP Status 404 the requested resource is not available / Spring boot
HTTP Status 404 - /CheckListMavenWebThree/checklist
type Status report
message /CheckListMavenWebThree/checklist
description The requested resource is not available.
Apache Tomcat/7.0.81
When I am hitting url in Postman for json data (Displays as mentioned below rather than json value from database)

I am confused with what url should I hit either with project name and path value (mentioned in controller class) like 8080/CheckListMavenWebThree/checklist or 8080/CheckListMavenWebThree like this?

Looks like the context path CheckListMavenWebThree is not defined in your properties, so http://localhost:8080/CheckListMavenWebThree/checklist it's going to throw 404. You add to your properties file:
server.contextPath=/CheckListMavenWebThree
or just hit your app like this,
http://localhost:8080/checklist
Hope this helps
