泽西岛CRUD-更新和发布无效

Question

这是我第一次无法正常使用Java Service类，我也不知道原因。

我有20多个服务类，除这一类外，其他所有类均工作正常：

 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以外，所有这些方法都可以正常工作。 实际上，@ GET方法有效。 我有关该类的域类称为“ 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; } } 

这是我称为FactoryDao的工厂类：

 package it.jack.fdd.dao; import it.jack.fdd.dao.impl.AccTypeDaoImpl; import it.jack.fdd.dao.impl.BaseDaoImpl; import it.jack.fdd.dao.impl.CapacityDaoImpl; import it.jack.fdd.dao.impl.CategoryDaoImpl; import it.jack.fdd.dao.impl.DispenserDaoImpl; import it.jack.fdd.dao.impl.FamilyDaoImpl; import it.jack.fdd.dao.impl.FeedbackDaoImpl; import it.jack.fdd.dao.impl.GeoAreaDaoImpl; import it.jack.fdd.dao.impl.IndustryDaoImpl; //import it.jack.fdd.dao.impl.InnerDaoImpl; import it.jack.fdd.dao.impl.ProducerDaoImpl; import it.jack.fdd.dao.impl.ProductDaoImpl; import it.jack.fdd.dao.impl.ProductDescDaoImpl; import it.jack.fdd.dao.impl.RtDispenserCategoryDaoImpl; import it.jack.fdd.dao.impl.RtFamilyProductDaoImpl; import it.jack.fdd.dao.impl.RtIngredientProductDaoImpl; import it.jack.fdd.dao.impl.RtStaffDispenserDaoImpl; import it.jack.fdd.dao.impl.StaffDaoImpl; import it.jack.fdd.dao.impl.StaffLoginDaoImpl; import it.jack.fdd.dao.impl.StaffTypeDaoImpl; import it.jack.fdd.dao.impl.TokenStaffDaoImpl; import it.jack.fdd.dao.interfaces.AccTypeDao; import it.jack.fdd.dao.interfaces.BaseDao; import it.jack.fdd.dao.interfaces.CapacityDao; import it.jack.fdd.dao.interfaces.CategoryDao; import it.jack.fdd.dao.interfaces.DispenserDao; import it.jack.fdd.dao.interfaces.FamilyDao; import it.jack.fdd.dao.interfaces.FeedbackDao; import it.jack.fdd.dao.interfaces.GeoAreaDao; import it.jack.fdd.dao.interfaces.IndustryDao; //import it.jack.fdd.dao.interfaces.InnerDao; import it.jack.fdd.dao.interfaces.ProducerDao; import it.jack.fdd.dao.interfaces.ProductDao; import it.jack.fdd.dao.interfaces.ProductDescDao; import it.jack.fdd.dao.interfaces.RtDispenserCategoryDao; import it.jack.fdd.dao.interfaces.RtFamilyProductDao; import it.jack.fdd.dao.interfaces.RtIngredientProductDao; import it.jack.fdd.dao.interfaces.RtStaffDispenserDao; import it.jack.fdd.dao.interfaces.StaffDao; import it.jack.fdd.dao.interfaces.StaffLoginDao; import it.jack.fdd.dao.interfaces.StaffTypeDao; import it.jack.fdd.dao.interfaces.TokenStaffDao; public class FactoryDao { //SINGLETON private FactoryDao() { } static class Holder { static public final FactoryDao ISTANCE = new FactoryDao(); } private BaseDao basedao = new BaseDaoImpl(); private DispenserDao dispenserdao = new DispenserDaoImpl(); private GeoAreaDao geoareadao = new GeoAreaDaoImpl(); private ProductDao productdao = new ProductDaoImpl(); private RtIngredientProductDao rtingredientproductdao = new RtIngredientProductDaoImpl(); private StaffDao staffdao = new StaffDaoImpl(); private StaffLoginDao stafflogindao = new StaffLoginDaoImpl(); private StaffTypeDao stafftypedao = new StaffTypeDaoImpl(); private TokenStaffDao tokenstaffdao = new TokenStaffDaoImpl(); private ProductDescDao productdescdao = new ProductDescDaoImpl(); private ProducerDao producerdao = new ProducerDaoImpl(); private FamilyDao familydao = new FamilyDaoImpl(); private RtFamilyProductDao rtfamilyproductdao = new RtFamilyProductDaoImpl(); private CategoryDao categorydao = new CategoryDaoImpl(); private RtDispenserCategoryDao rtdispensercategorydao = new RtDispenserCategoryDaoImpl(); private RtStaffDispenserDao rtstaffdispenserdao = new RtStaffDispenserDaoImpl(); private IndustryDao industrydao = new IndustryDaoImpl(); private CapacityDao capacitydao = new CapacityDaoImpl(); private AccTypeDao acctypedao = new AccTypeDaoImpl(); private FeedbackDao feedbackdao = new FeedbackDaoImpl(); public BaseDao createBaseDao(){ return basedao; } public DispenserDao createDispenserDao(){ return dispenserdao; } public GeoAreaDao createGeoAreaDao(){ return geoareadao; } public ProductDao createProductDao(){ return productdao; } public RtIngredientProductDao createRtIngredientProductDao(){ return rtingredientproductdao; } public StaffDao createStaffDao(){ return staffdao; } public StaffLoginDao createStaffLoginDao(){ return stafflogindao; } public StaffTypeDao createStaffTypeDao(){ return stafftypedao; } public TokenStaffDao createTokenStaffDao(){ return tokenstaffdao; } public ProductDescDao createProductDescDao(){ return productdescdao; } public ProducerDao createProducerDao(){ return producerdao; } public FamilyDao createFamilyDao(){ return familydao; } public RtFamilyProductDao createRtFamilyProductDao(){ return rtfamilyproductdao; } public CategoryDao createCategoryDao(){ return categorydao; } public RtDispenserCategoryDao createRtDispenserCategoryDao(){ return rtdispensercategorydao; } public RtStaffDispenserDao createRtStaffDispenserDao(){ return rtstaffdispenserdao; } public IndustryDao createIndustryDao(){ return industrydao; } public CapacityDao createCapacityDao(){ return capacitydao; } public AccTypeDao createAccTypeDao(){ return acctypedao; } public FeedbackDao createFeedbackDao(){ return feedbackdao; } public static FactoryDao getIstance() { return Holder.ISTANCE; } } 

（与其他类的工作一样，我不需要包括基于实现的方法更新和插入）

例如，我尝试我的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 } 

响应为204（可以），但没有任何反应：

我不明白是什么原因。

Answer 1

解决了。 问题是因为“读”。 “ read”也是mySql的系统变量。 解决了重命名问题
