Building Applications with Spring 5 and Vue.js 2

Setter-based/method-based injection

The second way is to declare a method, usually a setter, and apply the @Autowired annotation or the @Required annotation to it. For example, we can remove the MessageService constructor and add a setRepository(MessageRepository) method, as follows:

public class MessageService {   ...   @Required   public void setRepository(MessageRepository repository) {     this.repository = repository;   }   ...}

Or, you can name it something else, such as the following:

@Autowiredpublic void prepare (MessageRepository repository) {  this.repository = repository;}
