@Value vs @Bean Execution Order in Spring

The execution order of @Value and @Bean annotations in Java is as follows:

  1. Firstly, the @Value annotation will be resolved before the Spring container instantiates the Bean, injecting the values from the annotation into the annotated properties.
  2. The @Bean annotation is used to define a method that the Spring container will call to create a Bean instance. The @Bean annotation will be executed during the process of instantiating the Bean.
  3. Therefore, the execution order of the @Value annotation is before the @Bean annotation.

In summary, the @Value annotation is executed before the @Bean annotation because the @Value annotation is used to inject property values, while the @Bean annotation is used to define a Bean instantiation method.
