supports

boolean supports(java.lang.Class clazz)

Can this Validator validate instances of the supplied clazz?

This method is typically implemented like so:

return Foo.class.isAssignableFrom(clazz);

(Where Foo is the class (or superclass) of the actual object instance that is to be validated.)

参数:

clazz - the Class that this Validator is being asked if it can validate

返回:

true if this Validator can indeed validate instances of the supplied clazz

validate

void validate(java.lang.Object target,
              Errors errors)

Validate the supplied target object, which must be of a Class for which the supports(Class) method typically has (or would) return true.

The supplied errors instance can be used to report any resulting validation errors.

参数:

target - the object that is to be validated (can be null)

errors - contextual state about the validation process (never null)
