Hibernate例子

添加：

实体：

package cn.bdqn.entity;

public class Dog {
    private String name;
    private Integer age;
    private Integer id;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }
}

测试：

import cn.bdqn.entity.Dog;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class MytestAdd {
    //添加
    public static void main(String[] args) {
        Configuration cfg = new Configuration().configure();
        //session对象
        SessionFactory factory = cfg.buildSessionFactory();
        Session session = factory.openSession();

        //事物
        Transaction tx = session.beginTransaction();
        Dog dog = new Dog();
        dog.setName("盼盼");
        dog.setAge(20);
        session.save(dog);
        tx.commit();
        System.out.println("add ok!");
        session.close();
    }

查询：

  public static void main(String[] args) {
        Configuration cfg = new Configuration().configure();
        //session对象
        SessionFactory factory = cfg.buildSessionFactory();
        Session session = factory.openSession();
        Dog load = session.load(Dog.class,1);
        System.out.println(load.getName());
        System.out.println("add ok!");
        session.close();
}
