Hibernate验证器即使在违反约束的情况下也执行JAX-RS RESTendpoint

Question

我使用的是Hibernate Validator5.x和javax Validation1.x（由于一些原因，无法升级）。这个场景可以在hibernate Validator6.x和Validation2.x中工作

在违反约束时，Validator会启动并显示正确的错误响应，但同时它会执行REST方法体。

@POST
    @Path("/book")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Response createBook(@Valid Book book) {
        System.out.println("Book "+book);
        return Response.status(Response.Status.OK).entity(book).build();
    }

@ValidName
public class Book {

    private String name;
    private Author author;
    private double price;

    public Book() {
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Author getAuthor() {
        return author;
    }
    public void setAuthor( Author author) {
        this.author = author;
    }
    public double getPrice() {
        return price;
    }
    public void setPrice(double price) {
        this.price = price;
    }

}

@Constraint(validatedBy = { NameValidator.class })
@Target({ METHOD, FIELD, PARAMETER, TYPE })
@Retention(RUNTIME)
public @interface ValidName {
    String message() default "Author name is mandatory";

    Class<?>[] groups() default { };

    Class<? extends Payload>[] payload() default { };
}

@Provider
public class NameValidator implements ConstraintValidator<ValidName, Book>{

    @Override
    public boolean isValid(Book book, ConstraintValidatorContext context) {
        if(book == null) return true;

        if(book.getName().equals("")) {
            return true;
        }else {
            return !(book.getAuthor().getName().equals(""));
        }
    }
}

12:53:31,971 INFO  [stdout] (default task-1) Book com.arfat.entity.Book@3238e1e1

{
    "data": {},
    "messages": [
        "1. Author name is mandatory"
    ],
    "status": "ERROR-Bad Request"
}

我搜索了官方文件，但没有帮助。

类路径中有一个jar正在处理SessionContext。它上面有@Stateless注释。由于某种原因，它允许绕过验证。我不能删除这个jar，因为它是web应用程序所需要的，我正在相同的路径上部署reast-easy。所以需要找个工作
