spring配置上传文件大小，问题！

Question

在Spring 配置文件 xx-servlet.xml中配置  最大文件大小
    <!-- MultipartResolver for parsing file uploads, implementation for Commons FileUpload -->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- set the upload file's size to 1MB ????-->
        <property name="maxUploadSize">  
             <value>1048576</value>  
        </property>
        <property name="defaultEncoding">  
            <value>UTF-8</value>  
        </property> 
    </bean>上傳文件過大時，不會进入控制層，會直接在Servlet.service()中拋出異常，捕获不到。
需要捕獲到異常 提示用戶上傳文件過大。哪位有什麽好辦法么？謝謝!（不要說客戶端判断，IE7无法無法操作文件）2009-08-26 10:48:37,484 WARN [org.apache.catalina.core.StandardWrapperValve] - <Servlet.service() for servlet adp threw exception>

Answer 1

1 你再页面层再捕获一次
2 你可以写一个普通类，作为中间代理，在那里捕获异常。JPA等容器管理的，都会有这个问题。比较讨厌！

Answer 2

获取文件的大小,然后用JavaScript判断并提示.

Answer 3

给你提供几个上传的源码吧仿163网盘无刷新多附件上传源码JSP上传文件源代码JavaBean实现多文件上传

Answer 4

我也觉得这种方法不错，即给用户合理的提示，又省去了Server段的一堆处理。
当然server端必要的判断还是应该有的。
