Spring+SpringMVC+myBatis环境搭建

Spring+SpringMVC+myBatis环境搭建


第一步：引入Spring配置文件(放在src下)
第二步:引入jar包（20多个吧）
第三步：配置spring配置文件
注：以下配置包括Spring，都是基于注解的。

<!-- 声明数据源，并注入连接参数 -->
<bean id="ds" 
class="org.apache.commons.dbcp.BasicDataSource">
<property name="url" value="jdbc:mysql:///test?useUnicode=true&amp;characterEncoding=utf8"/>
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="username" value="root"/>
<property name="password" value="wangmeng"/>
</bean>
<!-- 声明SessionFactory 该工厂有spring提供 sqlSessionFactorybean-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入dataSource -->
<property name="dataSource" ref="ds"/>
<!-- Spring整合Mybatis它提供的这个工厂可以直接扫描mapper.xml因此这里需要注入要扫描的这些mapper.xml -->
<property name="mapperLocations" value="classpath:org/wangmeng/sql/*.xml"></property>
//这里是通配即该报下所有的xml文件都扫描
</bean>
<!-- 声明MapperSCannerConfigurer，该bean可以自动扫描指定包下所有的接口，并实现这些接口 -->
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 指定要扫描的包 -->
<property name="basePackage" value="org.wangmeng.dao"></property>
</bean>
<!-- 事物管理 -->
<bean id="tx" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<tx:annotation-driven transaction-manager="tx"/>
<!-- 开启IOC组建扫描-->
<context:component-scan

<!-- 开启Spring MVC注解 -->

<!--配置视图组建ViewResolver-->
<bean id="viewResolver" 


class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-


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


<!-- 设置aop实现方式 -->
<aop:aspectj-autoproxy/>
</beans>
第四步：配置web—xml
 <servlet>
  <servlet-name>springmvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
  <param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  <servlet-name>springmvc</servlet-name>
  <url-pattern>*.form</url-pattern>
  </servlet-mapping>
第五步：Mybatis映射文件(mapper.xml)
