記述一下步驟以備查。
準備工作：
需要把Jakarta Commons FileUpload及Jakarta Commons io的包放lib里。
我這邊的包是：
commons-fileupload-1.1.1.jar
commons-io-1.3.2.jar
然后在spring-servlet.xml進行multipartResolver配置，不配置好上傳會不好用。

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize"><value>100000</value></property><property name="defaultEncoding"><value>UTF-8</value></property> </bean> |
接下來就是頁面了：
注意Form的寫法和文件上傳組件的寫法。

<form action="uploadPosdetailFile.html" method="post" ENCTYPE="multipart/form-data"><div class="form" ><p><span class="req"><input id="startDateTxt" name="startDateTxt" class="field size4" title="Enter the date" /></span><label>Start Date: <span>(Date format:MM/dd/yyyy,eg:01/01/2014)</span></label></p><p><span class="req"><input id="endDateTxt" name="endDateTxt" class="field size4" title="Enter the date" /></span><label>End Date: <span>(Date format:MM/dd/yyyy,eg:12/25/2014)</span></label></p><p><span class="req"><input type="file" name="uploadFileCtrl" class="field size4" title="Choose the file" /></span><label>Upload file: <span>(click browse to choose)</span></label></p></div><div class="buttons"><input id="queryBtn" type="Submit" class="button" value="Submit" /></div></form> |
再在控制器里寫處理代碼，注意參數和頁面控件的對應關系：
