            <param-value>classpath*:/spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

<!-- Spring配置 -->
<!-- ====================================== -->
<listener>
   <listenerclass>
     org.springframework.web.context.ContextLoaderListener

<!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
<context-param>

    <!-- 启用spring mvc 注解 -->
    <context:annotation-config />

    <!-- 设置使用注解的类所在的jar包 -->
    <context:component-scan base-package="controller"></context:component-scan>

    <!-- 完成请求和注解POJO的映射 -->
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
　　
    <!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/jsp/" p:suffix=".jsp" />

　　
 <!-- 静态文件访问 -->
    <!-- <mvc:resources mapping="/resources/**" location="/resources/" /> -->

    <!-- 用于返回json格式 -->
    <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
