java - 数据库没有生成表

Question

嗨，我正忙于使用 Hibernate 和 Spring 开发 Java EE 应用程序。我有一个我运行的文章类(class)。但没有为其生成表。控制台中没有错误。

这是 Article 类:

package com.bd.entity;

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

@Entity
@Table(name="Articlet")
public class Article {

    int id;
    String nom;
    String type;
    int qte;


    public Article() {
        super();
        // TODO Auto-generated constructor stub
    }
    @Id
    @GeneratedValue
     @Column(name="ID")
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }
     @Column(name="Nom")
    public String getNom() {
        return nom;
    }
    public void setNom(String nom) {
        this.nom = nom;
    }
     @Column(name="Type")
    public String getType() {
        return type;
    }
    public void setType(String type) {
        this.type = type;
    }
     @Column(name="Qunatité")
    public int getQte() {
        return qte;
    }
    public void setQte(int qte) {
        this.qte = qte;
    }




}

和 ArticleDao 类:

package com.bd.dao;

import java.util.Collection;
import java.util.List;



import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.bd.entity.Article;
@Repository
@Transactional
@Configuration
public class ArticleDaoImp implements ArticleDao {

    @Autowired
    SessionFactory sessionFactory;

    @SuppressWarnings("unchecked")
    @Transactional(readOnly = true)
    public List<Article> getAll() {

        return sessionFactory.getCurrentSession().createQuery("from Article")
                .list();
    }

    @Transactional(readOnly = true)
    public Article getById(int articleId) {

        return (Article) sessionFactory.getCurrentSession().get(Article.class,
                articleId);
    }

    @Override
    public void save(Article article) {
        sessionFactory.getCurrentSession().merge(article);

    }

    @Override
    public void delete(Article article) {
        sessionFactory.getCurrentSession().delete(article);

    }

}

这是 hibernateataccesscontext 文件:

    et jdbc.properties

hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

问题是没有生成数据库结构。请帮忙。

Answer 1

在 Hibernate 配置 xml 中，确保将 hibernate.hbm2ddl.auto 设置为 update、create 或 创建-删除。
