Question

我有一个Reservation服务，使用请求 - 响应和DAO模式进行预订。我正在尝试使用Spring构建一个简单的REST API，允许我创建，搜索，编辑和删除有关预订的信息。信息通过JSON发送和返回。问题是我正在尝试使用Bean Validation，服务似乎完全忽略它。

Reservation.java

package org.prueba01.model;

import javax.validation.constraints.NotNull;

import org.hibernate.validator.constraints.Length;
import org.hibernate.validator.constraints.NotEmpty;

public class Reservation {

    private int id;

    @NotNull(message="El nombre es obligatorio.")
    @NotEmpty(message="El nombre no puede estar vacio.")
    private String name;

    @NotNull(message="Es obligatorio indicar el numero de personas.")
    @NotEmpty(message="El numero de personas no puede estar vacio.")
    @Length(min=1, max=15, message="El numero de personas debe ser entre 1 y 15.")
    private int people;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getPeople() {
        return people;
    }
    public void setPeople(int people) {
        this.people = people;
    }   

}

ReservationRequest.java

package org.prueba01.model;

import javax.validation.Valid;
import javax.validation.constraints.NotNull;
import org.hibernate.validator.constraints.NotEmpty;

public class ReservationRequest {

    @NotNull(message="No puede haber campos nulos.")
    @NotEmpty(message="No puede haber campos vacios.")
    @Valid
    private Reservation reservation;

    public Reservation getReservation(){
        return reservation;
    }

    public void setReserva (Reservation reservation){
        this.reservation=reservation;
    }

}

ReservationResponse.java

package org.prueba01.model;

import java.util.List;

public class ReservationResponse {

    private List<Reservation> reservations;
    private String errorMsg;    
    private boolean success=true;

    public List<Reservation> getReservations(){
        return reservations;
    }

    public void setReservations (List<Reservation> reservations){
        this.reservations=reservations;
    }

    public Boolean isSuccess(){
        return success;
    }

    public void setSuccess (boolean success){
        this.success=success;
    }

    public String getErrorMsg(){
        return errorMsg;
    }

    public void setErrorMsg(String errorMsg){
        this.errorMsg=errorMsg;
    }

}

IReservationDao.java

ReservationDaoImpl.java

    public Reservation searchReservation (int id){

                return reservation;
            }
        }

        throw new RuntimeException ("Reserva con el id " +id + " no encontrada!");
    }

    public List<Reservation> showAll(){
        return reservations;
    }

    public void addReservation (Reservation reservation){
        reservations.add(reservation);
        reservation.setId(counter.getAndIncrement());

    }

    public void changeReservation (Reservation reservation){
        Reservation reservationToChange = searchReservation(reservation.getId());

        reservationToChange.setId(reservation.getId());
        reservationToChange.setName(reservation.getName());
        reservationToChange.setPeople(reservation.getPeople());
    }

    public void cancelReservation(int id){
        Reservation reservationToCancel = searchReservation(id);        
        reservations.remove(reservationToCancel);
    }
}

我尝试过Apache 7和8个版本。请求通过

进行

本地主机：8080 / prueba01 /服务/休息/ ReservationManager / REST_CALL

所有这些似乎都很好。但是，如果我尝试测试任何Bean验证;例如，发送POST请求

本地主机：8080 / prueba01 /服务/休息/ ReservationManager / addReservation

部分为空的JSON，如

{ “预订”：{ “人”： “3”}}

该服务正常工作，它为“name”值引入了一个空值，而不是使服务崩溃。任何想法为什么会发生这种情况？

注意1：我还将cxf-2.7.6 jar添加到我的lib文件夹中，因为我无法通过Maven使用它，不知道为什么。

注意2：我还没有尝试过处理Bean Validation Exceptions，因为我只是想确保它们暂时发生。

提前致谢。

Answer 1

您是否尝试过遵循CXF提供的ValidationFeature文档？也许这可以解决你的问题： http://cxf.apache.org/docs/validationfeature.html#ValidationFeature-CommonBeanValidation1.1Interceptors

另一种解决方案是使用Validator手动验证请求。如果第一个解决方案无效，我可以为您提供一个示例。

祝你有个美好的一天。

Bean验证无效
