How to change default 8080 port in SpringBoot?

Question

My SpringBoot hello world program by default starting on 8080 port. How can I change this to my desired port?

There are couple of ways provided by spring to change the port.

# 1. Adding configuration in application.properties  ( easiest way )
If you are already using the `application.properties` in your application then great all you need to do is just add the following line to your `application.properties` file

```java
server.port = 8888
```
If you do not have `application.properties` in your application then simply create a new one in `src/main/resources`

# 2. Pass it as VM arguments
Let say your application is already packaged (for example as a fat jar) then you will have options to change the code, in those cases you can always pass the following VM Arguments to change the default port. 
```sh
-Dserver.port=8888
```
