8080 port already taken issue when trying to redeploy project from Spring Tool Suite IDE

Question

I have strange thing when I try to modify Spring project inside my Spring Tool Suite. On the first load (deploy) everything is fine, application compiles and runs on localho

Answer 1

You have to stop the current process and run your new one. In Eclipse, you can press this button to ReLaunch your application:

Answer 2

Open "localhost:8080" on your browser and see what is running on this port. I did it and I just found Oracle 10g XE running on background, so I went to start->Services and stopped all oracle services. Then I redo mvnw spring-boot:run on IntelliJ and it runs like magic.

Answer 3

Create application.properties file under src/main/resources folder and write content as

server.port=8084

Its runs fine. But every time before run need to stop application first by click on red button upper on the IDE

or try

RightClick on console>click terminate/Disconnect All

Answer 4

Just click red button to stop all services on eclipse than re- run application as Spring Boot Application - This worked for me.
