Annotation @Profile

The annotation @Profile to only enable the Bean for that specific spring profile.

For example:

@Getter  
@Setter  
public class DataSource {  
  private String url;  
}

@Configuration  
public class MyConfiguration {  
  @Bean  
  @Profile("!prod")  
  public DataSource nonProdDataSource() {  
    DataSource dataSource = new DataSource();  
    dataSource.setUrl("sit url");  
    return dataSource;  
  }  
  
  @Bean  
  @Profile("prod")  
  public DataSource prodDataSource() {  
    DataSource dataSource = new DataSource();  
    dataSource.setUrl("prod url");  
    return dataSource;  
  }  
}

As a result, when setting spring.profiles.active: prod (see Spring Property Profile), only the datasource with prod url is enabled.
