Java jersey中的自定义ValidationError类仅发送字符串错误消息

jersey2.x的ValidationError类如下所示

@XmlRootElement
public final class ValidationError {
 private String message;
    private String messageTemplate;
    private String path;
    private String invalidValue;
 
    ...
}

Contact with given ID does not exist. (path = ContactCardResource.getContact.<return value>, invalidValue = null)

当发生错误时，返回如下字符串

@XmlRootElement
public final class ValidationError {
 private String message;
    private String messageTemplate;
    private String path;
    private String invalidValue;
 
    ...
}

Contact with given ID does not exist. (path = ContactCardResource.getContact.<return value>, invalidValue = null)

具有给定ID的联系人不存在。（path=ContactCardResource.getContact.，invalidValue=null）

但我需要的是客户端的一致错误消息响应接口。它应该只发送字符串消息。所以这不应该包括类名和方法名。对于一些不依赖于bean验证的验证，例如重复用户名。我只发送带有400或500状态码的字符串。我想对Bean验证做同样的事情，如何实现这一点

Bean验证抛出

ConstraintViolationException

，您可以编写一个自定义异常映射器来处理

ConstraintViolationException

，如下所示

@Singleton
@Provider
public class ConstraintViolationMapper implements ExceptionMapper<ConstraintViolationException> {

@Override
public Response toResponse(ConstraintViolationException e) {
    // There can be multiple constraint Violations
    Set<ConstraintViolation<?>> violations = e.getConstraintViolations();
    List<String> messages = new ArrayList<>();
    for (ConstraintViolation<?> violation : violations) {
        messages.add(violation.getMessage());

    }
    return Response.status(Status.BAD_REQUEST).entity(StringUtils.join(messages,";")).build();
}

}

@Singleton
