spring_day06_SSH框架整合_XML方式

标签: SSH

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;

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>
	</bean>

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
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

		<action name="*_Customer" class="customerAction" method="{1}">
			<result name="list_success">/jsp/customer/list.jsp</result>
		</action>

	</package>
</struts>

Action动作类

package com.itheima.web.action;

import java.util.List;

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

public class CustomerAction extends ActionSupport {

	private CustomerService customerService;

	public void setCustomerService(CustomerService customerService) {
		this.customerService = customerService;
	}

	private List<Customer> list;

	public List<Customer> getList() {
		return list;
	}

	public String list() throws Exception {
		list = customerService.findAllCustomer();
		return "list_success";
	}

}
