记述一下步骤以备查。
准备工作:
需要把Jakarta Commons FileUpload及Jakarta Commons io的包放lib里。
我这边的包是:
commons-fileupload-1.1.1.jar
commons-io-1.3.2.jar
然后在spring-servlet.xml进行multipartResolver配置,不配置好上传会不好用。

<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> |
接下来就是页面了:
注意Form的写法和文件上传组件的写法。

<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> |
再在控制器里写处理代码,注意参数和页面控件的对应关系:
