I'm using the @AllArgsConstructor annotation in my class and want to be sure that arguments will be not null.
Is there a way to modify this annotation to make this possible, or I should implement constractor?
Thanks
@Getter
@Setter
@ToString
@AllArgsConstructor
public class Contact {
private String name;
private String phoneNumber;
}
...
<lombok.version>1.16.18</lombok.version>

But if you add a constructor with parameters (or @AllArgsConstructor ), then you'll need to add a no args constructor (or @NoArgsConstructor ) as well, for JPA/Hibernate to work.
An all-args constructor requires one argument for every field in the class. Complete documentation is found at the project lombok features page for @Constructor. Even though it is not listed, this annotation also has the onConstructor parameter.
The @AllArgsConstructor annotation generates a constructor with one parameter for every field in the class. Fields that are annotated with @NonNull result in null checks with the corresponding parameters in the constructor. The annotation won't generate a parameter for the static and initialized final fields.
The constructor will throw a NullPointerException if any of the parameters intended for the fields marked with @NonNull contain null . The order of the parameters match the order in which the fields appear in your class. @AllArgsConstructor generates a constructor with 1 parameter for each field in your class.
Yes, you have to use @ NonNull on such fields, it will result in a null check in the generated constructor.

@RequiredArgsConstructor
Generates a constructor with required arguments. Required arguments are final fields and fields with constraints such as @NonNull. Complete documentation is found at the project lombok features page for @Constructor . Even though it is not listed, this annotation also has the onConstructor parameter. See the full documentation for more details.
