Hibernate注解方式单表操作

首先就是修改我们的hibernate.cfg.xml文件

<!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.username">username</property>
<property name="connection.url">jdbc:db2://</property>
<property name="connection.password">pswd</property>
<property name="dialect">org.hibernate.dialect.DB2Dialect</property>
<property name="connection.driver_class">com.ibm.db2.jcc.DB2Driver</property>
<property name="show_sql">true</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<mapping class="bean.ZqTest"/>这点是与用配置文件映射有区别的
</session-factory>
</hibernate-configuration>

由于是使用注解，所以就不再需要hbm.xml文件了

ZqTest.java文件如下

package bean;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="ZQTEST2")//name为表名
public class ZqTest {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="ID")
private int id;

@Column(name="NAME")
private String name;

@Column(name="AGE")
private int age;

public ZqTest()
{

}
public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

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;
}


}
这就OK了，我们就可以测试了。
