1.整体项目结构

注：bean包为entity类,dao和service为接口,impl为实现类

2.maven之pom依赖：

<dependencies>
    
    
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>

3.整合之application.xml

4.web.xml

    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

5.serviceImpl 与daoImpl具体实现
