ssm框架整合思路及代码
1、Dao层:
网站的建设创新互联公司专注网站定制,经验丰富,不做模板,主营网站定制开发.小程序定制开发,H5页面制作!给你焕然一新的设计体验!已为食品包装袋等企业提供专业服务。
mybatis整合spring,通过spring创建数据库连接池,管理SqlSessionFactory、mapper代理对象。需要mybatis和spring的整合包
创建SqlMapConfig.xml配置文件
"1.0"encoding="UTF-8"?>
PUBLIC"-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
创建applicationContext-dao.xml
xmlns:context="http://www.springframework.org/schema/context"xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
http://www.springframework.org/schema/utilhttp://www.springframework.org/schema/util/spring-util-4.2.xsd">
destroy-method="close">
为了便于更改数据库,编写db.properties文件
jdbc.driver=数据库驱动
jdbc.url=jdbc:MySQL://localhost:3306/数据库名称?characterEncoding=utf-8
jdbc.username=用户名
jdbc.password=密码
2、Service层:
所有的service实现类都放到spring容器中管理。由spring管理实务。
创建applicationContext-service.xml
"1.0"encoding="UTF-8"?>
xmlns:context="http://www.springframework.org/schema/context"xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-4.2.xsd
http://www.springframework.org/schema/utilhttp://www.springframework.org/schema/util/spring-util-4.2.xsd">
创建applicationContext-trans.xml
xmlns:context="http://www.springframework.org/schema/context"xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
http://www.springframework.org/schema/utilhttp://www.springframework.org/schema/util/spring-util-4.2.xsd">
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
pointcut="切入点表达式" />
为了加载spring容器,在Web.Xml中编写如下
"1.0"encoding="UTF-8"?>
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
3、表现层:
Springmvc框架,由springmvc管理controller
创建Springmvc.xml
"1.0"encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.2.xsd">
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
为了加载前端控制器(DispatcherServlet),在web.xml中编写如下
"1.0"encoding="UTF-8"?>
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
