今天练习Hibernate整合Spring的候发现报只读的错误。
原因再没整合之前，事务需要自己提交。整合后事务交给Spring容器来管理！

下面是自己写的测试类，正常代码运行

1.POJO类–User
2.Dao层–添加User
3.测试

/***实体类*/package com.tedu.pojo;public class User {    private Integer uid;    private String uname;    private String password;    //省略get，set方法。。。    @Override    public String toString() {        return "User [uid=" + uid + ", uname=" + uname + ", password=" + password + "]";    }}

User.hbm.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping>    <class name="com.tedu.pojo.User" table="sys_user" >        <id name="uid" column="uid" >            <generator class="native" />        </id>        <property name="uname" column="uname"/>        <property name="password" column="password"/>    </class></hibernate-mapping>

Dao层实现

package com.tedu.dao;import org.springframework.orm.hibernate5.support.HibernateDaoSupport;import org.springframework.transaction.annotation.Transactional;import com.tedu.pojo.User;@Transactional//重点再这里,一定要添加这个事务注解public class UserDaoImpl extends HibernateDaoSupport implements UserDao {    /**     * 添加用户     */    @Override    public void save(User user) {        this.getHibernateTemplate().save(user);    }    /**     * 按照ID查询用户     */    @Override    public User getUserById(Integer uid) {        return this.getHibernateTemplate().get(User.class, uid);    }}

最后是测试

package com.tedu.test;import javax.annotation.Resource;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.tedu.dao.UserDao;import com.tedu.pojo.User;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration("classpath:spring/applicationContext.xml")public class HibernateDemo {    @Resource    private UserDao userDao;    @Test    public void run1(){        User user = new User();        user.setUname("慧敏");        user.setPassword("123456");        userDao.save(user);        System.out.println("插入成功");    }}

最后是Spring整合Hibernate
