开发流程，注意：每个hibernate版本在集成的时候是不太一样的。本次使用的是hibernate-distribution-3.6.10.Final-dist
一、开发流程
1）在数据库中创建表，代码如下：
CREATE TABLE USER(
id INT PRIMARY KEY AUTO_INCREMENT,
uName VARCHAR() NOT NULL,
uGender CHAR(),
uBirthday DATE);
2）在工程中创建实体类
public class User {
private int id;
private String uName;
private String uGender;
private Date uBirthday;
public User() {
// TODO Auto-generated constructor stub
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getuName() {
return uName;
}
public void setuName(String uName) {
this.uName = uName;
}
public String getuGender() {
return uGender;
}
public void setuGender(String uGender) {
this.uGender = uGender;
}
public Date getuBirthday() {
return uBirthday;
}
public void setuBirthday(Date uBirthday) {
this.uBirthday = uBirthday;
}3）创建对象和表的映射文件，*.hbm.xml。User.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping
package="com.huitong.entity"> <class name="User" table="user"> <id name="id" column="id">
<generator class="native"/>
</id> <property name="uName" column="uName"></property>
<property name="uGender" column="uGender"></property>
<property name="uBirthday" column="uBirthday"></property> </class>
</hibernate-mapping>
4）hibernate的配置文件，放在src/目录下。hibernate.cfg.xml.
包含两部分
- 数据库连接配置
- 加载映射文件
<!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>
<!-- 配置数据库连接 -->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql:///day17?useSSL=true</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> <property name="hibernate.show_sql">true</property> <!-- 加载映射文件 -->
<mapping resource="com/huitong/entity/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>
小技巧：在myeclipse中要将多个jar文件配置到classpath中：
<1>首先点中第一个jar包
<2>shift+点击最后一个jar文件，选中所有jar文件
5）简单测试
public void fun1(){
User user = new User();
user.setuName("good");
user.setuBirthday(new Date());
Configuration configuration = new Configuration();
configuration.configure();
SessionFactory sf = configuration.buildSessionFactory();
Session session = sf.openSession();
Transaction bt = session.beginTransaction();
session.save(user);
bt.commit();
session.close();
sf.close();
}5）当有多个配置文件时，使用include进行包含
<include file="com/baidu/action/AdminConfig.xml"></include>
