Question

这是Java Service类第一次无法正常运行，我不知道原因。

我有超过20个服务类，除此之外的所有服务类都完美无缺：

package it.jack.fdd.services;

import java.util.List;

import javax.ws.rs.GET;
import javax.ws.rs.HeaderParam;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import it.jack.fdd.dao.FactoryDao;
import it.jack.fdd.domain.Feedback;
import it.jack.fdd.domain.Staff;
import it.jack.fdd.domain.StaffType;
import it.jack.fdd.dto.StaffDto;
import it.jack.fdd.dto.StaffTypeDto;
import it.jack.fdd.dto.TokenStaffDto;
import it.jack.fdd.util.ConverterDTO;

@Path("/feedback")
public class FeedbackServices {
	
	@GET
	@Produces(MediaType.APPLICATION_JSON)
	public List<Feedback> getFeedback() {
	
        List<Feedback> listOfFeedback = FactoryDao.getIstance().createBaseDao().getAll(Feedback.class);
			return listOfFeedback;
		
	}
	
	@GET
	@Path("/notread")
	@Produces(MediaType.APPLICATION_JSON)
	public List<Feedback> getFeedbackNoRead(@HeaderParam("token") String token) {
		TokenStaffDto ts = new TokenStaffDto();
		StaffDto s = new StaffDto();
		StaffTypeDto st = new StaffTypeDto();
		
		
		Boolean ex = FactoryDao.getIstance().createTokenStaffDao().getExistence(token);
		ts = ConverterDTO.converterTokenStafftoDTO(FactoryDao.getIstance().createTokenStaffDao().getTokenStaffFromToken(token));
		s = ConverterDTO.converterStafftoDTO((Staff) FactoryDao.getIstance().createBaseDao().getById(ts.getIdtokenStaff(), Staff.class));
		st = ConverterDTO.converterStaffTypetoDTO( (StaffType) FactoryDao.getIstance().createBaseDao().getById(s.getStaffType().getIdstaffType(),
				StaffType.class));

		if (ex && st.getIdstaffType() == 1) { 
			List<Feedback> listOfFeedback = FactoryDao.getIstance().createFeedbackDao().notRead();
			return listOfFeedback;
		}else
			return null;
		
	}
	
	@GET
	@Path("/{id}")
	@Produces(MediaType.APPLICATION_JSON)
	public Object getFeedbackById(@PathParam("id") int id, @HeaderParam("token") String token) {
		TokenStaffDto ts = new TokenStaffDto();
		StaffDto s = new StaffDto();
		StaffTypeDto st = new StaffTypeDto();
		
		
		Boolean ex = FactoryDao.getIstance().createTokenStaffDao().getExistence(token);
		ts = ConverterDTO.converterTokenStafftoDTO(FactoryDao.getIstance().createTokenStaffDao().getTokenStaffFromToken(token));
		s = ConverterDTO.converterStafftoDTO((Staff) FactoryDao.getIstance().createBaseDao().getById(ts.getIdtokenStaff(), Staff.class));
		st = ConverterDTO.converterStaffTypetoDTO( (StaffType) FactoryDao.getIstance().createBaseDao().getById(s.getStaffType().getIdstaffType(),
				StaffType.class));

		if (ex && st.getIdstaffType() == 1) { 
			return FactoryDao.getIstance().createBaseDao().getById(id, Feedback.class);
		}else
			return null;
	}
	
	@POST
	@Produces(MediaType.APPLICATION_JSON)
	public int addFeedback(Feedback feedback/*, @HeaderParam("token") String token*/) {

			return FactoryDao.getIstance().createBaseDao().save(feedback);

	}

	@PUT
	@Produces(MediaType.APPLICATION_JSON)
	public void updateFeedback(Feedback feedback) {

			FactoryDao.getIstance().createBaseDao().update(feedback);


	}

}

除了@PUT和@POST之外，所有这些方法都能很好地工作。实际上@GET方法有效。我关于这个类的域类称为“Feedback.java”：

package it.jack.fdd.domain;
// Generated 30-nov-2016 0.17.09 by Hibernate Tools 4.3.1.Final

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import static javax.persistence.GenerationType.IDENTITY;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

/**
 * Feedback generated by hbm2java
 */
@Entity
@Table(name = "feedback", catalog = "fdd_dbproducts")
public class Feedback implements java.io.Serializable {

	private Integer idfeedback;
	private User user;
	private String message;
	private boolean read;

	public Feedback() {
	}

	public Feedback(User user, String message, boolean read) {
		this.user = user;
		this.message = message;
		this.read = read;
	}

	@Id
	@GeneratedValue(strategy = IDENTITY)

	@Column(name = "idfeedback", unique = true, nullable = false)
	public Integer getIdfeedback() {
		return this.idfeedback;
	}

	public void setIdfeedback(Integer idfeedback) {
		this.idfeedback = idfeedback;
	}

	@ManyToOne(fetch = FetchType.EAGER)
	@JoinColumn(name = "fkuser_feedback", nullable = false)
	public User getUser() {
		return this.user;
	}

	public void setUser(User user) {
		this.user = user;
	}

	@Column(name = "message", nullable = false, length = 45)
	public String getMessage() {
		return this.message;
	}

	public void setMessage(String message) {
		this.message = message;
	}

	@Column(name = "read", nullable = false)
	public boolean isRead() {
		return this.read;
	}

	public void setRead(boolean read) {
		this.read = read;
	}

}

这是我的工厂类叫FactoryDao：

	public  static FactoryDao getIstance() {
		return Holder.ISTANCE;
	}

}

（我不需要包含基于实现的方法更新和插入，就像其他类一样工作）

例如，我尝试了我的GET METHOD，我有这个JSON文件：

[
  {
    "idfeedback": 1,
    "user": {
      "iduser": 1,
      "name": "Andrea",
      "surname": "Pirlo",
      "birthDate": "1980-12-12",
      "cityResidence": "Cannole",
      "provinceResidence": "Lecce",
      "postalCode": "73020",
      "gender": true,
      "bankAccounts": [],
      "userLogin": {
        "iduserLogin": 1,
        "email": "ciao96@libero.it",
        "pass": "asdasd5sada5adsdsadasdas6dsa6da5dadad",
        "tokenUser": null
      }
    },
    "message": "migliorare controlli",
    "read": false
  },
  {
    "idfeedback": 2,
    "user": {
      "iduser": 1,
      "name": "Andrea",
      "surname": "Pirlo",
      "birthDate": "1980-12-12",
      "cityResidence": "Cannole",
      "provinceResidence": "Lecce",
      "postalCode": "73020",
      "gender": true,
      "bankAccounts": [],
      "userLogin": {
        "iduserLogin": 1,
        "email": "ciao96@libero.it",
        "pass": "asdasd5sada5adsdsadasdas6dsa6da5dadad",
        "tokenUser": null
      }
    },
    "message": "sdfsdf",
    "read": false
  }
]

我想以这种方式编辑第一项：

{
    "idfeedback": 1,
    "user": {
      "iduser": 1,
      "name": "Andrea",
      "surname": "Pirlo",
      "birthDate": "1980-12-12",
      "cityResidence": "Cannole",
      "provinceResidence": "Lecce",
      "postalCode": "73020",
      "gender": true,
      "bankAccounts": [],
      "userLogin": {
        "iduserLogin": 1,
        "email": "ciao96@libero.it",
        "pass": "asdasd5sada5adsdsadasdas6dsa6da5dadad",
        "tokenUser": null
      }
    },
    "message": "update",
    "read": true
  }

响应是204（没关系）但没有任何反应：

我不明白是什么原因。

Answer 1

解决。问题是因为＆＃34;读＆＃34;。＆＃34;读＆＃34;也是mySql的系统变量。解决了重命名问题
