Non-recommended field injections

Reports injected or autowired fields in Spring components.

The quick-fix suggests the recommended constructor-based dependency injection in beans and assertions for mandatory fields.

Example:

class MyComponent {
  @Inject MyCollaborator collaborator; // injected field

  public void myBusinessMethod() {
    collaborator.doSomething(); // throws NullPointerException
  }
}

After applying the quick-fix:

class MyComponent {

  private final MyCollaborator collaborator;

  @Inject
  public MyComponent(MyCollaborator collaborator) {
    Assert.notNull(collaborator, "MyCollaborator must not be null!");
    this.collaborator = collaborator;
  }

  public void myBusinessMethod() {
    collaborator.doSomething(); // now this call is safe
  }
}
