2.Web.xml

1.上下文监听spring配置文件；

2.mvc的核心控制器


<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

        <filter-name>HiddenHttpMethodFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

3. 配置spring核心文件application.xml

1). 包扫描

2). 读取数据库配置文件xx.properties

3). 数据源(可以是c3p0，或其他)

4). 工厂bean对象(SqlSessionFactoryBean)

a. dataSource-ref（引用）

b. typeAliasesPackage(包别名)

c. mapperLocations(映射文件*Mapper.xml)

5). 映射扫描管理器(MapperScannerConfigurer)

a. basePackage(持久层接口包路径)

b. sqlSessionFactoryBeanName（配置string类型SqlSessionFactoryBean的id引用）

6). 事务管理器(DataSourceTransactionManager)

a. dataSource-ref=” “（引用数据源）
b. 开启事务注解

XML代码


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4 SpringMVC.xml

    <mvc:default-servlet-handler/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>
</beans>
