使用异常映射器的JAX-RS

InvalidDataException是否包装在PersistenceException中？也许您可以执行以下操作：

@Provider public class PersistenceMapper implements ExceptionMapper<PersistenceException> {    @Override     public Response toResponse(PersistenceException arg0) {         if(arg0.getCause() instanceof InvalidDataException) {return Response.status(Response.Status.BAD_REQUEST).build();         } else {...        }    }}
