实体JAVA类和XML文件：

package com.domain;

public class User {
    private Integer id;

    private String email;

    private String username;

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public Integer getId() {
        return id;
    }

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

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

}

XML映射配置文件：

<?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="com.domain.User" table="User"  >
        <id name="id" type="integer">
            <column name="ID" />
            <generator class="increment" />
        </id>
        <property name="username" type="string">
            <column name="USERNAME" length="16"  />
        </property>
        <property name="email" type="string">
            <column name="EMAIL" length="256" />
        </property>
    </class>
</hibernate-mapping>

DAO代码：

package com.dao;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.transaction.annotation.Transactional;

import com.domain.User;

public class UserDao extends HibernateDaoSupport {
    /**
     * 更新某一字段的操作。并使用事务管理。
     */
    @Transactional
    public void updateField() {
//        getHibernateTemplate().bulkUpdate("update com.domain.User set username = '管理员4' where id = 1 ");
        // 有意制造异常
//        getHibernateTemplate().bulkUpdate("update spring.User2 set username = '管理员4' where id = 1 ");

        User u = new User();
        u.setUsername("xx");
        getHibernateTemplate().save(u);

        User u1 = new User();
        u1.setUsername("x111111111111111111111111111111111111111111111111111111111111111111111111111x");
        getHibernateTemplate().save(u1);


    }



}

测试代码：

package com.test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.dao.UserDao;

public class TestMain {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext("NewFile.xml");
        UserDao um = (UserDao) appContext.getBean("myTarget");
        um.updateField();
    }

}
