整合前的说明
-
独立式整合指的是三个框架都使用自己的配置文件
-
引入式整合指的是hibernate主配置文件中的内容都配置到spring配置文件中
-
在整合过程中,确保每步都运行成功,然后在继续往下做
-
整合中使用的案例是客户的保存和列表查询操作
-
后面的三种整合方式都基于1.2中的环境准备
数据库
create database crm;
/*创建客户表*/
CREATE TABLE `cst_customer` (
`cust_id` bigint(32) NOT NULL AUTO_INCREMENT COMMENT '客户编号(主键)',
`cust_name` varchar(32) NOT NULL COMMENT '客户名称(公司名称)',
`cust_source` varchar(32) DEFAULT NULL COMMENT '客户信息来源',
`cust_industry` varchar(32) DEFAULT NULL COMMENT '客户所属行业',
`cust_level` varchar(32) DEFAULT NULL COMMENT '客户级别',
`cust_address` varchar(128) DEFAULT NULL COMMENT '客户联系地址',
`cust_phone` varchar(64) DEFAULT NULL COMMENT '客户联系电话',
PRIMARY KEY (`cust_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

搭建struts2框架
导入jar包
在web.xml文件中,添加struts2拦截器

编写Action动作类
基于XML方式的独立式整合
spring整合hibernate
明确
-
Spring和Hibernate的整合就是spring接管SessionFactory的创建
-
Spring针对Hiberante的操作有一个封装的对象HibernateTemplate
-
和JdbcTemplate一样,HibernateTemplate也有一个HibernateDaoSupport
-
HibernateTemplate和HibernateDaoSupport都在spring-orm-4.2.4.RELEASE.jar中
-
我们Dao采用继承HiberanteDaoSupport的方式编写,只能用于XML配置
在spring配置文件中配置SessionFactory
<!-- 配置数据源(连接池) -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
</bean>
改造Dao继承HibernateDaoSupport
package com.itheima.dao.impl;
import java.util.List;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport;
import com.itheima.dao.CustomerDao;
import com.itheima.domain.Customer;
public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {
@Override
public void saveCustomer(Customer customer) {
System.out.println("dao方法执行了");
this.getHibernateTemplate().save(customer);
}
@Override
public List<Customer> findAllCustomer() {
return (List<Customer>) this.getHibernateTemplate().find("from Customer");
}
}
在spring配置文件中给Dao注入SessionFactory
<!-- 创建DAO实例 -->
<bean id="customerDao" class="com.itheima.dao.impl.CustomerDaoImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
修改hibernate核心配置文件
去掉Session绑定到当前线程上
配置Spring的事务
- 配置事务管理器
<!-- 配置事务管理器 -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<!-- 注入SessionFactory -->
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
- 配置事务的通知及通知的属性
<!-- 配置事务的传播行为 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<!-- 配置事务的属性 -->
<tx:attributes>
<tx:method name="*" read-only="false" propagation="REQUIRED" />
<tx:method name="find*" read-only="true" propagation="SUPPORTS" />
</tx:attributes>
</tx:advice>
- 配置AOP建立切入点表达式和事务通知的关系
<!-- 配置切面 -->
<aop:config>
<!-- 配置通用切入点表达式 -->
<aop:pointcut expression="execution(* com.itheima.service.impl.*.*(..))"
id="pt1" />
<!-- 建立事务通知和切入点表达式的对应关系 -->
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt1" />
</aop:config>
- 整合hibernate之后的spring核心配置文件

在spring配置文件中添加Action配置
<!-- 配置Action -->
<bean id="customerAction" class="com.itheima.web.action.CustomerAction"
scope="prototype">
<!-- 注入service -->
<property name="customerService" ref="customerService"></property>

修改struts.xml文件
在spring配置文件中配置Action,在struts2配置文件action标签的class属性里写bean的id
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

import com.itheima.service.CustomerService;
import com.opensymphony.xwork2.ActionSupport;

public String list() throws Exception {
