hibernate 开发步骤

1 创建Customer表
CREATE TABLE CUSTOMER
(
CID int NOT NULL PRIMARY KEY ,
USERNAME varchar(20)  ,
PASSWORD varchar(20)
)

2 创建Customer表对应的Java类POJO
package hibtest;

public class Customer
{
private int id;
private String username;
private String password;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}

}

3 配置hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">com.microsoft.jdbc.sqlserver.SQLServerDriver</property>
<property name="connection.url">jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=WebDB</property>
<property name="connection.username">sa</property>
<property name="connection.password">jsj</property>

<property name="connection.pool_size">2</property>
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="show_sql">true</property>

<mapping resource="Customer.hbm.xml"/>

</session-factory>
</hibernate-configuration>

4 创建Customer.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
'-//Hibernate/Hibernate Mapping DTD 3.0//EN'
'http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd'>
<hibernate-mapping>
<class name="testhi.Customer" table="CUSTOMER">
<id name="id" column="CID">
<generator class="assigned"/>
</id>
<property name="username" column="USERNAME" />
<property name="password" column="PASSWORD" />
</class>
</hibernate-mapping>

5 编写测试程序
SessionFactory sf =   new Configuration().configure().buildSessionFactory();
//Configuration cfg = new Configuration().configure();
//cfg.addURL(Test.class.getResource("/Customer.hbm2.xml"));
//SessionFactory sf = cfg.buildSessionFactory();

Session session = sf.openSession();
Transaction tx = session.beginTransaction();

for (int i = 0; i < 200; i++) {
Customer customer = new Customer();
customer.setId(i);
customer.setUsername("customer" + i);
customer.setPassword("customer");
session.save(customer);
}
tx.commit();
session.close();
