Spring boot and Bean validation in different methods and the same class

Question

I'm doing a rest webservice with spring boot and I would like to know if is possible do different validations with bean validation annotations by method with a POJO as param in the controller layer.

example:

POJO:

    Public class Person{
            @NotNull(forMethod="methodOne")
            private String firstName;
            @NotNull(forMehotd="methodTwo")
            private String lastName;
            private String age;

            //getter and setter
    }

Controller

    @RestController
    public class controller{

        @RequestMapping(....)
        public ResponseEntity methodOne(@Valid @RequestBody Person person){
            .....
        }

        @RequestMapping(....)
            public ResponseEntity methodTwo(@Valid @RequestBody Person person){
            ......
        }
    }

I know that is possible do it with separate parameters in the methods, but I have a POJO with so many attributes. is it possible do something like that?

I think you should use validation groups in your bean validation annotations and use @Validated annotation instead of @Valid annotation. because @Validated annotation has a value properties that specifies a group for validation.

for example:

Public class Person{
        @NotNull(groups={MethodOne.class})
        private String firstName;
        @NotNull(groups={MethodTwo.class})
        private String lastName;
        private String age;

        //getter and setter
}

and

@RestController
public class controller{

    @RequestMapping(....)
    public ResponseEntity methodOne(@Validated(MethodOne.class) @RequestBody Person person){
        .....
    }

    @RequestMapping(....)
        public ResponseEntity methodTwo(@Validated(MethodTwo.class) @RequestBody Person person){
        ......
    }
}

by the way, don't forget that you should create MethodOne and MethodTwo interfaces to use them as your validation groups.
