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。
