03.SSM框架整合-Spring整合SpringMVC

配置springmvc.xml

创建springmvc.xml文件作为springmvc的核心配置文件放如resources目录下,springmvc.xml详细配置如下:

     <!-- springmvc只扫描自己的controller包-->
    <context:component-scan base-package="com.lg.controller">
         <!-- springmvc只扫描Controller注解-->
         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/" />
        <property name="suffix" value=".jsp" />
    </bean>


    <!--过滤静态资源   .js .css png-->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />
        
	<!-- 配置注解形式适配器和映射器 -->
	<mvc:annotation-driven />
	
	<!-- 文件上传 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<!-- 文件最大上传大小-->
		<property name="maxUploadSize">
			<value>5242880</value>
		</property>
	</bean>
	
	<!-- 配置拦截器-->
	<mvc:interceptors>
		<mvc:interceptor>
			<mvc:mapping path="/**" />
			<bean class="com.green.interceptor.LoginInterceptor"></bean>
		</mvc:interceptor>
	</mvc:interceptors>

配置Web.xml

web.xml配置如下:

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

  <display-name>SSM</display-name>
  <!-- 加载spring的配置文件 通过全局初始化参数加载 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!-- 解决post请求中文乱码 -->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>utf-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- 在启动tomcat的时候就启动springIOC容器, 此时需要添加一个监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 配置前段控制器 -->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 加载springmvc的配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>
</web-app>
