Springboot use different implementation class depending on environment

Issue

I am using Springboot 3 with Java20.

I am looking for the simplest way to use a different implementation depending on the environment.

I have the following interface:

MyService

public interface MyService {
    boolean send(String fileName, final String userName);
}

With two implementations:

MyService1Impl

@Service
@Qualifier("myService1Impl")
public class MyService1Impl implements MyService {

MyService2Impl

@Service
@Qualifier("myService2Impl")
public class MyService2Impl implements MyService {

Then I want to use the following:

@Autowired
private @Qualifier("myService1Impl") MyService myService1Impl;
@Autowired
private @Qualifier("myService2Impl") MyService myService2Impl;

// if @Profile("dev") use myService1Impl
// if @Profile("*") use myService2Impl

I would like to keep this as simple as possible (not to have to use @Cofiguration if possible).

Solution

you don't need @Qualifier in this case just replace them with @Profile("nameOfYourProfile"):

@Service
@Profile("dev")
public class MyService1Impl implements MyService {

and

@Service
@Profile("!dev")
public class MyService2Impl implements MyService {
