简单的使用hibernate插入数据的例子
数据库创建脚本:
- drop table person
- create table person(
- id varchar(32) not null primary key,
- name varchar(20) not null,
- password varchar(20) not null,
- sex varchar(20) ,
- email varchar(30)
- )
Person类
- package org.lz.hibernate;
- public class Person { //POJO类
- private String id;
- private String name;
- private String password;
- private String sex;
- private String email;
- public String getId() {
- return id;
- }
- public void setId(String id) {
- this.id = id;
- }
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getPassword() {
- return password;
- }
- public void setPassword(String password) {
- this.password = password;
- }
- public String getSex() {
- return sex;
- }
- public void setSex(String sex) {
- this.sex = sex;
- }
- public String getEmail() {
- return email;
- }
- public void setEmail(String email) {
- this.email = email;
- }
- }
PersonOperator类:
- package org.lz.hibernate;
- import org.hibernate.Session;
- import org.hibernate.SessionFactory;
- import org.hibernate.Transaction;
- import org.hibernate.cfg.Configuration;
- public class PersonOperator {
- private Session session = null;
- public PersonOperator() {
- Configuration config = new Configuration();
- SessionFactory factory = config.configure().buildSessionFactory();
- this.session = factory.openSession();
- }
- // 所有的操作都是通过session来完成的
- public void PersonInsert(Person p) {
- Transaction tran = this.session.beginTransaction();//开始事物
- this.session.save(p);//执行
- tran.commit();//提交
- }
- }
测试方法:
- package org.lz.hibernate;
- public class TestPO {
- public static void main(String[] args) {
- Person p = new Person();
- p.setId("1");
- p.setName("root");
- p.setPassword("123456");
- p.setSex("男");
- p.setEmail("[email protected]");
- //通过实例化的Person对象插入数据
- PersonOperator po = new PersonOperator();
- po.PersonInsert(p);
- }
- }
