一、构建Hibernate项目
1.新建Java项目HibernateDemo1
2.导入Hibernate下的jar包(lib->required下的所有jar包)+jdbc驱动包
3.导入hibernate.cfg.xml文件到src目录下(在Hibernate文件目录中搜索*.cfg.xml)
配置该文件如下:
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.url">jdbc:mysql:///hibernate_db</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">root</property> <property name="hibernate.hbm2ddl.auto">update</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> <mapping resource="com\eduask\pojo\Person.hbm.xml" /> </session-factory> </hibernate-configuration>
4.建立mysql数据库hibernate_db
5.在src目录下建两个包com.eduask.pojo、com.eduask.test
pojo包下建一个Person类(Person.java),内容如下:
package com.eduask.pojo;
import java.util.Date;
public class Person {
private Integer id;
private String name;
private int password;
private Date birthday;
public Person() {}
public Person(String name, int password, Date birthday) {
super();
this.name = name;
this.password = password;
this.birthday = birthday;
}
@Override
public String toString() {
return "Person [id=" + id + ", name=" + name + ", password=" + password + ", birthday=" + birthday + "]";
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getPassword() {
return password;
}
public void setPassword(int password) {
this.password = password;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
} pojo包下引入xml文件Person.hbm.xml,(Hibernate包中搜索),修改内容如下:
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping SYSTEM "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd" > <hibernate-mapping> <class name="com.eduask.pojo.Person" table="t_person"> <id name="id"> <generator class="native"/> </id> <property name="name" column="t_name"></property> <property name="password" length="6"></property> <property name="birthday"></property> </class> </hibernate-mapping>
test包中新建测试类HibernateTest.java,内容如下:
package com.eduask.test;
import java.util.List;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import com.eduask.pojo.Person;
public class HibernateTest {
public static void main(String[] args) {
Configuration config = new Configuration().configure();
SessionFactory factory = config.buildSessionFactory();
Session session = factory.openSession();
Transaction tx = session.beginTransaction();
Person p = new Person("admin",123456,new java.util.Date());
Criteria c = session.createCriteria(Person.class);
List<Person> lists = c.list();
System.out.println(lists.get(0).getName());
tx.commit();
session.close();
factory.close();
}
} 运行测试类,结果如下:
Hibernate:
insert
into
t_person
(t_name, password, birthday)
values
(?, ?, ?)
八月 11, 2016 5:17:14 下午 org.hibernate.service.jdbc.connections.internal.DriverManagerConnectionProviderImpl stop
INFO: HHH000030: Cleaning up connection pool [jdbc:mysql:///hibernate_db]
同时在数据库中可以看到t_person表已被创建以及插入的响应数据。
