spring+mybatis+springmvc的配置

1.web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    
    <!-- 上下文参数（第一启动），指定jdbc配置文件位置  -->
    <context-param>
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:/config/jdbc.xml</param-value>  
      </context-param>     
     
    <!-- spring监听器（第二启动），监听springMvc环境 -->
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  
    
    <!-- springMvc编码拦截器（第三启动），springMvc内置的编码拦截器 -->
    <filter>  
        <filter-name>encodingFilter</filter-name>  
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
    </filter>  
     
    <filter-mapping>  
        <filter-name>encodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>
      
      <!-- springMvc前置总控制器（第四启动），在分发其它的控制器前都要经过这个总控制器 -->
    <servlet>  
        <servlet-name>spring-mvc</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    <init-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:/config/springmvc.xml</param-value>  
    </init-param>  
    <load-on-startup>2</load-on-startup>  
    </servlet>  
     
    <servlet-mapping>  
        <servlet-name>spring-mvc</servlet-name>  
        <url-pattern>*.do</url-pattern>  
    </servlet-mapping>  
    
    <!-- 网站的默认首页   -->
    <welcome-file-list>
        <welcome-file>begin.jsp</welcome-file>
    </welcome-file-list>
</web-app>

2.spring 的配置文件applicationContext-mybatis.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring"

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"
        lazy-init="false">
        <property name="dataSource" ref="dataSource" />

        <property name="basePackage" value="com.ltf.springmvc.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>
    <mybatis-spring:scan base-package="com.ltf.springmvc.dao" />

</beans>

3.jdbc的配置

    <!-- 启动时扫描所有的controller -->
    <context:component-scan base-package="com.springmvc.web" />

    <!--  主要作用于@Controller，激活该模式，下面是一种简写形式，完全可以手动配置替代这种简写形式，它会自动注册DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter，是spring MVC为@Controllers分发请求所必须的   -->
    <mvc:annotation-driven />

    <!-- 配置js,css等静态文件直接映射到对应的文件夹，不被DispatcherServlet处理 -->
    <mvc:resources location="/WEB-INF/resources/**" mapping="/resources" />

    <!-- jsp页面解析器，当Controller返回XXX字符串时，先通过拦截器，然后该类就会在/WEB-INF/views/目录下，查找XXX.jsp文件 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/views/" />
