SpringMVC 返回JSON和JSP页面xml配置

代码1：

<!-- DispatcherServlet Context: defines this servlet‘s request-processing 
        infrastructure -->

    <!-- Enables the Spring MVC @Controller programming model -->
    <annotation-driven />

    <!-- Handles HTTP GET requests for /resources/** by efficiently serving 
        up static resources in the ${webappRoot}/resources directory -->
    <resources mapping="/resources/**" location="/resources/" />

    <!-- Resolves views selected for rendering by @Controllers to .jsp resources 
        in the /WEB-INF/views directory -->
    <beans:bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">

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

    <context:component-scan base-package="com.sun4j.app" />

    <!-- 避免IE在ajax请求时，返回json出现下载 -->
    <!-- 返回json 方法二 需要导入 jackson-annotations.jar,jackson-core.jar,jackson-databind.jar-->  
   <beans:bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
    <beans:bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
