How validate method parameters are NotNull by default in spring method validation?

2

Here is example about method validation. So check method paramerter as not null I have to write the follolwing:

import org.springframework.validation.annotation.Validated



@Validated

public class SomeClass {

    public void myMethod(@NotNull Object p1, @Nullable Object p2) {}

}

Is there a way to setup spring bean validation to make all parameters validated as @NotNull by default? E.g. the following will fail when p1 is null:

import org.springframework.validation.annotation.Validated



@Validated

public class SomeClass {

    public void myMethod(Object p1, @Nullable Object p2) {}

}

Any ideas?

You can write your own @NotNullArgs annotation as an option

@Target(ElementType.METHOD)

@Retention(RetentionPolicy.RUNTIME)

public @interface NotNullArgs {

}

And aspect:

@Aspect

@Component

public class ArgumentMatcher {



  @Around(value = "@annotation(NotNullArgs)")

  public Object verifyAuthorities(ProceedingJoinPoint joinPoint) throws Throwable {

     final Optional<Object> nullArg = Arrays.stream(joinPoint.getArgs())

       .filter(Objects::isNull)

       .findFirst();



     if (nullArg.isPresent() && joinPoint.getArgs().length > 0) {

       throw new IllegalArgumentException(); // or NPE

     } else {

       return joinPoint.proceed();

     }

  }

}

Then you can use it like this:

@NotNullArgs

void methodToCall(Obj arg1, Obj arg2) { .... }

It's just a draft, but you can use this code as a point to start

If you would like Spring to automatically validate method arguments do this:

1. add org.hibernate.validator:hibernate-validator to your dependencies


2. mark the required method arguments with @javax.validation.constraints.NotNull
   

then when you call such method and do not provide the required argument you will get a javax.validation.ConstraintViolationException exception.

another approach, a lot easier, is to use Lombok's: just mark the method argument with @lombok.NonNull and Lombok will do the rest.
