java - Programmatic and declarative Constraint declaration -

i'm validating beans through kind of code:

validator validator = validation.builddefaultvalidatorfactory().getvalidator(); validator.validatevalue(class, propertyname, value); 

my classes this:

public static interface primitive {     public primitive setstring(string s);      @notnull     public string getstring(); } 

this working fine far. seems it's not possible plain hibernate validator constraint definitions/mapping given class , add additional constraints described here. looks constraint mapping manual, don't todo. on other side beandescriptor validator.getconstraintsforclass(class) seems not usable constraintmapping.

this have in mind:

constraintmapping mapping = new constraintmapping();  mapping     .type(order.class).getconstraints()/*reads constraints declared on bean*/         .property("customer", elementtype.field)/*add additional constraints*/             .constraint(notnulldef.class); validator validator = validation     .byprovider(hibernatevalidator.class)     .configure()     .addmapping(mapping)     .buildvalidatorfactory()     .getvalidator(); 

the programmatic constraint api additive, meaning don't need suggested getconstraints. see validator online docs - http://docs.jboss.org/hibernate/stable/validator/reference/en-us/html_single/#section-programmatic-api

by default, constraints added via fluent api additive constraints configured via standard configuration capabilities. possible ignore annotation , xml configured constraints required.
