Spring @Required Annotation deprecated?

Question

I am trying to add @Required Annotation to my bean but complier says it's deprecated.

public class Product {
    private String id;
    
    public String getId() {
        return id;
    }

    @Required
    public void setId(String id) {
        this.id = id;
    }
}

Is there a different annotation for this?

Answer 1

Read the documentation:

Deprecated as of 5.1, in favor of using constructor injection for required settings (or a custom InitializingBean implementation).

public class Product {
   private String id;

   public Product(String id) {
      this.id = id;
   }

   public String getId() {
      return id;
   }

Answer 2

Just use @Autowired.

@Autowired
public void setId(String id) {
    this.id = id;
}

Answer 3

One of the best answer i got is this :

@Autowired(required = true)
private String yourVariable;

if you set it required to false your String value will be null and you won't get an error

if you just typed @Autowired, then it is required = true by default, try these to understand and read console error messages
