我正在尝试使用restful web services创建项目。我收到错误

org.hibernate.hql.internal.ast.QuerySyntaxException：网站不是映射

。我已经尝试了每个解决方案来解决这个错误。请查看我的代码，如果有任何建议请告诉我。谢谢你

GifController：

  package com.gif.code.controller;

  import java.util.List;

  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.web.bind.annotation.PathVariable;
  import org.springframework.web.bind.annotation.RequestBody;
  import org.springframework.web.bind.annotation.RequestMapping;
  import org.springframework.web.bind.annotation.RequestMethod;
  import org.springframework.web.bind.annotation.RestController;

  import com.gif.code.model.GifModel;
  import com.gif.code.service.GifService;

  @RestController
  public class GifController {

    @Autowired
    GifService gifService;

    @RequestMapping(value = "/getAllData", method = RequestMethod.GET,  headers = "Accept=application/json")
    public List<GifModel> getData() {
        System.out.println("In Controller");
        List<GifModel> listOfData = gifService.getAllData();
        return listOfData;
    }

    @RequestMapping(value = "/getData/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
    public GifModel getDataById(@PathVariable int id) {
        return gifService.getData(id);
    }

    @RequestMapping(value = "/addData", method = RequestMethod.POST, headers = "Accept=application/json")
    public void addData(@RequestBody GifModel gifModel) {   
        gifService.addData(gifModel);

    }

}

GifModel：

    package com.gif.code.model;

    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.GenerationType;
    import javax.persistence.Id;

    @Entity
    @Table(name="WEBSITE")
    public class GifModel {

    @Id
    @Column(name="id")
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    int id;

    @Column(name="title")
    String title;   

    @Column(name="description")
    String description;

    public GifModel() {
        super();
    }
    public GifModel(int i, String title,String description) {
        super();
        this.id = i;
        this.title = title;
        this.description=description;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getDescription() {
        return description;
    }
    public void setDescription(String description) {
        this.description = description;
    }
}

GifService：

    package com.gif.code.service;


import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.gif.code.dao.GifDao;
import com.gif.code.model.GifModel;

@Service("gifService")
public class GifService {

    @Autowired
    GifDao gifDao;

    @Transactional
    public List<GifModel> getAllData() {
        System.out.println("In Service");
        return gifDao.getAllData();
    }

    @Transactional
    public GifModel getData(int id) {
        return gifDao.getData(id);
    }

    @Transactional
    public void addData(GifModel gifmodel) {
        gifDao.addData(gifmodel);
    }

}

GifDao：

package com.gif.code.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.gif.code.model.GifModel;

@Repository
public class GifDao {

    @Autowired
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sf) {
        this.sessionFactory = sf;
    }

    @SuppressWarnings("unchecked")
    public List<GifModel> getAllData() {
        System.out.println("In Dao");
        Session session = this.sessionFactory.getCurrentSession();
        List<GifModel> textList = session.createQuery("from Website").list();
        return textList;
    }

    public GifModel getData(int id) {
        Session session = this.sessionFactory.getCurrentSession();
        GifModel gifmodel = (GifModel) session.load(GifModel.class, new Integer(id));
        return gifmodel;
    }

    public GifModel addData(GifModel gifmodel) {
        Session session = this.sessionFactory.getCurrentSession();
        session.persist(gifmodel);
        return gifmodel;
    }

Answer 1

HQL适用于不使用表名的类名！

所以你必须写：

List<GifModel> textList = session.createQuery("from GifModel").list();

错误：org.hibernate.hql.internal.ast.QuerySyntaxException：未映射网站
