将特定的约束验证器映射到泽西州的特定ContraintViolationException [英] Mapping specific constraint validator to specific ContraintViolationException in Jersey

问题描述

我正在尝试创建一个自定义验证器并将其映射到特定的constraintViolationException。原因是我想为不同的约束创建不同的自定义异常。例如，如果在数据库中找不到用户，则会触发找不到的violationException，而如果用户具有无效的用户名，则会执行错误的responseException violationException。

$ p $ @Retention（RUNTIME）
@Target（{FIELD，METHOD}）
@Constraint（validatedBy = UserNotValidValidator.class）
public @interface UserIsValid {...}


映射到

  public class ConstraintExceptionMapper实现
 ExceptionMapper< ConstraintViolationException> {
 public Response toResponse（ConstraintViolationException e）{...} 
} 
  

更具体地说，问题是bean hibernate验证器是否支持多个约束异常映射器。

解决方案

异常映射器是一个概念JAX-RS不是Bean验证。您应该为 ConstraintViolationException 创建一个异常映射器，并根据给定违例异常中包含的违规情况创建不同的响应。例如。你可以通过`ConstraintViolation.getConstraintDescriptor（）。getAnnotation（）。annotationType（）。
来检查违反的约束类型

I am trying to create a custom validator and mapped it into a specific constraintViolationException. The reason is I want to create different custom exception for different constraint. For example, if a user is not found in the database, a not found violationException is triggered, while if the user has invalid username, a bad response violationException will be executed instead.

@Retention(RUNTIME)
@Target({ FIELD, METHOD })
@Constraint(validatedBy = UserNotValidValidator.class)
public @interface UserIsValid { ... }

mapped into

public class ConstraintExceptionMapper implements
    ExceptionMapper<ConstraintViolationException> {
   public Response toResponse(ConstraintViolationException e) { ... }
}

To be more specific, the question is whether bean hibernate validator supports multiple constraint exception mapper.

解决方案

Exception mappers are a concept of JAX-RS not of Bean Validation. You should create one exception mapper for ConstraintViolationException and have it create different responses based on the violations contained within a given violation exception. E.g. you can examine the violated constraint type via `ConstraintViolation.getConstraintDescriptor().getAnnotation().annotationType().
