How can I set default constraints on all my properties in hibernate validator

I want to automatically put @Valid constraints on all my properties.

Example:

public class Adult extends MyBeanValidationAbstractClass{
    @Min(18)
    public Inte开发者_如何学Pythonger age;
    @NotBlank
    public String name;
    public Dog dog;
    public Cat cat;
}

I want the Validator to think that all properties have the @Valid annotation.

How can this can be achieved?

So in you example, you want Dog and cat to be annotated with @Valid. I guess Integer and String should not be affected? I dont think that you can automate this, who else but you should know, which requirements your attributes have?

--- Edit: just re-read ... you dont to write the annotations, you want to controll the Validator.

You could write a custom Constraint-Annoation for your type

@ValidAttributes
public class MyClass {
...
}

and then use a custome Validator for that annotation. Then you could use reflection to iterate over all your attributes and validate them.

The honest answer is: bean validation is not following convention over configuration - you have to put @Valid all over the place. IMHO bean validation has a fundamental design flaw.
