blog实现相册管理(文件上传＋目录管理)

<DIV>blog实现相册管理 目的: &nbsp;基于spring2.0实现blog相册管理，主要包括： &nbsp;目录管理:新建目录,修改目录,删除目录,查看目录 &nbsp;图片管理:图片文件,修改图片,删除图片,查看图片,移动图片 &lt;!--========================package=================================--&gt; 步骤: 一:包结构 -blog |&nbsp;&nbsp;&nbsp; |+config |&nbsp;&nbsp;&nbsp; |&nbsp; |-blog-servlet.xml |&nbsp;&nbsp;&nbsp; |+lib |&nbsp;&nbsp;&nbsp; |+src |&nbsp;&nbsp;&nbsp; |&nbsp;|-src |&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;&nbsp;&nbsp; |-com |&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;&nbsp;&nbsp; |&nbsp;|-wiscom |&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;|-file |&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;|&nbsp;&nbsp;&nbsp; |+model |&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;|&nbsp;&nbsp;&nbsp; |-web |&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;&nbsp;&nbsp; |&nbsp;|&nbsp;|&nbsp;&nbsp;&nbsp; |&nbsp; |-admin |&nbsp;&nbsp;&nbsp; |-web |&nbsp;&nbsp;&nbsp; |&nbsp;|+image |&nbsp;&nbsp;&nbsp; |&nbsp;|+upload |&nbsp;&nbsp;&nbsp; |&nbsp;|+WEB-INF |&nbsp;&nbsp;&nbsp; |&nbsp; |-build.xml &lt;!--======================spring fileupload==========================--&gt; 二:文件上传 1:说明:spring提供对分段文件上传（multipart file upload）的支持,Spring支持web应用中的分段文件上传。这种支持是由即插即用的MultipartResolver来实现。这些解析器都定义在org.springframework.web.multipart包里。Spring提供了现成的MultipartResolver可以支持Commons FileUpload(<A href="http://jakarta.apache.org/commons/fileupload">http://jakarta.apache.org/commons/fileupload</A>)和 COS FileUpload(<A href="http://www.servlets.com/cos">http://www.servlets.com/cos</A>)。本章后面的部分描述了Spring是如何支持文件上传的。 通常情况下，Spring是不处理文件上传的，因为一些开发者想要自己处理它们。如果想使用Spring的这个功能，需要在web应用的上下文中添加分段文件解析器。这样，每个请求就会被检查是否包含文件上传。如果没有，这个请求就被正常的处理，否则，应用上下文中已经定义的MultipartResolver就会被调用。然后，你请求中的文件属性就会像其它属性一样被处理。 &lt;!--=======================multipartResolver==========================--&gt; 2:本例子实现commons fileupload.先在工程lib中加入jar包commons-fileupload.jar。 &nbsp;在config中的blog-servlet.xml加入MultipartResolver &lt;bean id="multipartResolver" &nbsp;&nbsp; class="org.springframework.web.multipart.commons.CommonsMultipartResolver"&gt; &nbsp;&lt;!-- set the max upload size 500KB --&gt; &nbsp;&lt;property name="maxUploadSize"&gt; &nbsp;&nbsp;&nbsp;&nbsp; &lt;value&gt;51200&lt;/value&gt; &nbsp;&lt;/property&gt; &nbsp;&lt;property name="maxInMemorySize"&gt; &nbsp;&nbsp;&nbsp;&nbsp; &lt;value&gt;4096&lt;/value&gt; &nbsp;&lt;/property&gt; &lt;/bean&gt; &lt;!--==========================以下为model================================--&gt; &lt;!--==========================以下为model================================--&gt; &lt;!--==========================以下为model================================--&gt; &lt;!--=========================FileUpload.java=============================--&gt; 3:在blog\src\com\wiscom\file\model中实现FileUpload的model package com.wiscom.file.model;</DIV>
