Spring整合Hibernate

Spring整合Hibernate操作

1.创建web Project

2.添加jar包

Spring的jar包+Hibernate的jar包+数据库连接jar包 

3.书写配置文件

　　3.1 applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.springframework.org/schema/beans" 
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
    http://www.springframework.org/schema/beans/spring-beans-4.3.xsd  
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-4.3.xsd  
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.3.xsd ">
  <!--1.加载数据库的属性配置文件  --> 
  <context:property-placeholder location="classpath:dbinfo.properties" ></context:property-placeholder>
  <!-- 2.配置c3p0数据源 -->
  <bean name="ds" class="com.mchange.v2.c3p0.ComboPooledDataSource">
     <property name="driverClass" value="${driverClass}"></property>
     <property name="jdbcUrl" value="${jdbcUrl}"></property>
     <property name="user" value="${user}"></property>
     <property name="password" value="${password}"></property>
  </bean>
  <!-- 3.将Hibernate的sessionFactory对象交给Spring来创建管理维护 -->
  <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
      <!-- 3.1 注入数据源连接池信息 -->
      <property name="dataSource" ref="ds"></property>
      <!-- 3.2 hibernate的额外配置 (可选配置)-->
      <property name="hibernateProperties">
        <props>
          　<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
             <!-- 隔离级别 -->
            <prop key="hibernate.connection.isolation">4</prop>
            <!-- 目的：要使用getCurrentSession()获取当前线程绑定的Session，必须要做如下配置：必须要使用Spring提供的SpringSessionContext-->
 　　　　　　 <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</prop> 
        </props>
      </property>
      <!-- 3.3 加载映射文件(不能重复加载) -->
      <property name="mappingLocations" value="classpath:com/xx/domain/*.hbm.xml"></property>
  </bean>
　<!-- 2.配置dao层 -->
  <bean name="userDao" class="com.xx.dao.impl.UserDaoimpl">
     <!-- 注入sessionFatory对象 -->
     <property name="sessionFactory" ref="sessionFactory"></property>
  </bean>
  <!-- 3.配置service层 -->
  <bean name="userService" class="com.xx.service.impl.UserServiceimpl">
    <property name="userDao" ref="userDao"></property>
  </bean> 
　<!-- 4.配置事务管理 -->
  <bean name="tm" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
      <property name="sessionFactory" ref="sessionFactory"></property>
  </bean>
　<!-- 5.开启事务 (两种方式选一)-->
  <!-- 方式一：注解开启事务 -->
  <tx:annotation-driven transaction-manager="tm"/>
  <!-- 方式二：XML配置开启事务 -->
  <!-- 配置通知-->
  <tx:advice id="txAdvice" transaction-manager="tm">
      <tx:attributes>
          <tx:method name="*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false"/>
      </tx:attributes>
  </tx:advice>
  <!-- 配置切面 -->
  <aop:config proxy-target-class="true">
　　　　<!-- 配置切点 -->
      <aop:pointcut expression="execution(* com.itqf.service.impl.*Serviceimpl.*(..))" id="pt"/>
　　　　<!-- 织入 -->
      <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
  </aop:config>
</beans>  

　　3.2 web.xml(重点)

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
  <display-name>SSH_CRM</display-name>
 <!--监听web程序：在程序启动时就加载applicationContext.xml文件-->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--加载applicationContext.xml文件-->
<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>classpath:applicationContext2.xml</param-value> 
</context-param> </web-app> 

4.创建持久化类

package com.xx.domain;
public class User{
    private Integer id;
    private String name;
    private Integer age;
                        
    //省略set/get方法
} 

5.创建持久化类对应的映射文件(持久化类名.hbm.xml)

<?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 package="com.xx.domain">
    <class name="User" table="user">
        <id name="id">
            <generator class="native"></generator>
        </id>
        <property name="name"></property>
        <property name="age"></property>
    </class>
</hibernate-mapping>   

6.配置service层和dao层

    6.1 dao层实现类

//dao层实现类需要继承HibernateDaoSupport 在代码中使用getHibernateTemplate()
public class CustomerDaoimpl  extends  HibernateDaoSupport implements CustomerDao{
    @Override
    public void insertCustomer(User user) {
        getHibernateTemplate().save(customer);
    }
} 

　6.2 service层实现类

//方式一：注解配置事务
@Transactional
public class UserServiceimpl implements UserService{
     private UserDao userDao;
     public void setUserDao (UserDao userDao) {
        this.userDao= userDao;
    } 
     public void save(User user){
          userDao.insertUser(user);
     }                            
}
//方式二：xml配置事务
public class UserServiceimpl implements UserService{
     private UserDao userDao;
     public void setUserDao (UserDao userDao) {
        this.userDao= userDao;
    } 
     public void save(User user){
          userDao.insertUser(user);
     }                            
} 

7.测试

public class Test1{
    @Resource(name="userService") 
    private UserService userService;
    public void test1(){
        User user = new User();
        user.setId(1);
        user.setName("哈哈");
        user.setAge(123);
        userService.save(user);    
   }
}
