Question about Bean Validation 1.1

Hello,

I want to use the same POJO with 3 fields (field1, field2, field3) for 2 REST calls.
For the first REST call, I want to check that one of the 3 fields are not null and the 2 other ones are null.
For the second REST call, I want to check that at least one of the 3 fields is not null.

How to achieve that with Java Bean Validation 1.1 ?
I want to use Java Bean Validation group feature but what I don't get is that I can't use something like @Valid(group="mygroup") !
But programmatically, I can perform the following operation: validator.validate(myobject, "mygroup") !!!

Could someone help me to solve this issue ?

Best Regards.

I would recommend to use a dedicated POJO/DTO for each of the two services. If that's not viable, take a look at group conversion:

Code:

public void service1(@Valid @ConvertGroup(from=Default.class, to=Group1.class) MyDto dto) { ... }

public void service2(@Valid @ConvertGroup(from=Default.class, to=Group2.class) MyDto dto) { ... }
