Spring MVC+mybatis 环境搭建，总结

1、配置WEB.XML

<!-- 监听spring上下文容器 -->

<listener>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener>

<!-- 加载spring的xml配置文件到 spring的上下文容器中 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:*-context.xml</param-value>

</context-param>

<!-- 配置Spring MVC DispatcherServlet -->

<servlet>

<servlet-name>MVC</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<!-- 初始化参数 -->

<init-param>

<!-- 加载SpringMVC的xml到 spring的上下文容器中 -->

<param-name>contextConfigLocation</param-name>

<param-value>

/WEB-INF/classes/mvc-context.xml

</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<!-- 配置DispatcherServlet所需要拦截的 url -->

<servlet-mapping>

<servlet-name>MVC</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

2.MVC配置文件主要是实现后台与前台视图的映射

<context:component-scan base-package="com.wg.*" />

<bean id="viewResolver"

class="org.springframework.web.servlet.view.UrlBasedViewResolver">

<property name="viewClass"

value="org.springframework.web.servlet.view.JstlView" />

<property name="prefix" value="/page/" />

<property name="suffix" value=".jsp" />

</bean>

3.mybatis配置文件，主要是实现模型类与数据库映射类的配置

<configuration>

<typeAliases>

<package name="com.wg.bean" />

</typeAliases>

<mappers>

<mapper resource="com/wg/bean/UserMapper.xml" />

</mappers>

</configuration>

4、数据源配置文件

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

destroy-method="close">

<property name="driverClassName"><value>oracle.jdbc.driver.OracleDriver</value></property>

<property name="url"><value>jdbc:oracle:thin:@127.0.0.1:1521:ORCL</value></property>

<property name="username"><value>HUHU</value></property>

<property name="password"><value>123456</value></property>

</bean>

<!-- 创建SqlSessionFactory，同时指定数据源 -->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource" />

<property name="configLocation" value="classpath:mybatis-config.xml"></property>

</bean>

5.接口与mybatis，spring映射配置

<!-- 用户Dao -->

<bean id="userDao" class="org.mybatis.spring.mapper.MapperFactoryBean">

<property name="mapperInterface" value="com.wg.dao.UserDao" />

<property name="sqlSessionFactory" ref="sqlSessionFactory" />

</bean>
