基于spring2.0实现blog相册管理(文件上传＋目录管理)

 

blog实现相册管理
目的:
 基于spring2.0实现blog相册管理，主要包括：
 目录管理:新建目录,修改目录,删除目录,查看目录
 图片管理:图片文件,修改图片,删除图片,查看图片,移动图片
<!--========================package=================================-->
步骤:
一:包结构
-blog
|    |+config
|    |  |-blog-servlet.xml
|    |+lib
|    |+src
|    | |-src
|    | |    |-com
|    | |    | |-wiscom
|    | |    | | |-file
|    | |    | | |    |+model
|    | |    | | |    |-web
|    | |    | | |    |  |-admin
|    |-web
|    | |+image
|    | |+upload
|    | |+WEB-INF
|    |  |-build.xml
<!--======================spring fileupload==========================-->
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(http://jakarta.apache.org/commons/fileupload)和 COS FileUpload(http://www.servlets.com/cos)。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。
<!--=======================multipartResolver==========================-->
2:本例子实现commons fileupload.先在工程lib中加入jar包commons-fileupload.jar。
 在config中的blog-servlet.xml加入MultipartResolver
<bean id="multipartResolver"
   class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
 <!-- set the max upload size 500KB -->
 <property name="maxUploadSize">
     <value>51200</value>
 </property>
 <property name="maxInMemorySize">
     <value>4096</value>
 </property>
</bean>

3:在blog\src\com\wiscom\file\model中实现FileUpload的model
package com.wiscom.file.model;

public class FileUpload {
    private String parentDirectoryId;//文件存放在哪个虚拟目录下

 }

 public void setDescription(String description) {

 }

 }

 public void setFile(byte[] file) {
  this.file = file;
 }

 public String getParentDirectoryId() {
  return parentDirectoryId;
 }

 public void setParentDirectoryId(String parentDirectoryId) {
  this.parentDirectoryId = parentDirectoryId;
 }
}
<!--========================UploadFile.java============================-->
4:在blog\src\com\wiscom\file\model中实现UploadFile的model

sequnce:SEQ_WEBLOGFILE_ID和SEQ_WEBLOGDIRECTORY_ID能在插入记录是生成ID
GeneralUploadFileManager类继承AbstractUploadFileManager,AbstractUploadFileManager
把idGenerator作为自己的属性,AbstractUploadFileManager又继承JdbcDaoSupport,
