Hibernate自动创建表的两种方式（第二种方法）
Hibernate自动创建表的两种方式（第二种方法）（转）第二种方法首先：1.创建学生类package com.day02;public class Student {private int id;//定义成整形，但也可定义成字符串，但字符串有时不行，好奇怪。还是定义成整形。private String name;private int age;private String address;public Student(){}public Student(int id, String name, int age, String address) { super(); this.id = id; this.name = name; this.age = age; this.address = address;}public String getName() { return name;}public void setName(String name) { this.name = name;}public int getAge() { return age;}public void setAge(int age) { this.age = age;}public String getAddress() { return address;}public void setAddress(String address) { this.address = address;}public int getId() { return id;}public void setId(int id) { this.id = id;}}2.写配置文件<?xml version="1.0"?><hibernate-mapping package="com.day02"><class name="Student" table="Student"><id name="id" column="oid"><generator column="t_name"></property><property name="age" column="t_age"></property><property name="address" column="t_address"></property></class></hibernate-mapping>3.配置hibernate.cfg.xml<?xml version='1.0' encoding='UTF-8'?><!-- Generated by MyEclipse Hibernate Tools. --><hibernate-configuration><session-factory><property name="connection.username">root</property><property name="connection.url">jdbc:mysql://127.0.0.1/xiaogu</property><property name="dialect">org.hibernate.dialect.MySQLDialect</property><property name="myeclipse.connection.profile">com.mysql.jdbc.Driver</property><property name="connection.password">root</property><property name="connection.driver_class">com.mysql.jdbc.Driver</property><mapping resource="com/day02/Student.hbm.xml"></mapping><mapping resource="com/day02/Account.hbm.xml"></mapping></session-factory></hibernate-configuration>4.定义工具类package com.day02;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;public class HbnUtil {private static SessionFactory sf; static{Configuration conf = new Configuration().configure("hibernate.cfg.xml"); SchemaExport dbExport = new SchemaExport(conf); // dbExport.setOutputFile("d:/cxsql.txt");//首先在d盘创建一个叫cxsql.txt的空文档，程序会把生成的sql语句输出 dbExport.create(true, true); sf=conf.buildSessionFactory();} public static Session getSession(){ return sf.openSession(); } public static void closeSessionFactory(){ if(!sf.isClosed()){ sf.close(); } }}5.写测试类package com.day02;import org.hibernate.Session;public class Test {public static void main(String[] args) { Student stu=new Student(); stu.setAddress("hebei"); stu.setAge(23); stu.setName("xiaogu"); Session session=HbnUtil.getSession(); session.beginTransaction(); session.save(stu); session.getTransaction().commit(); session.close(); }}
