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:

is.close();
}
return "/pages/posdetail/uploadposdetailresult/index.jsp" ;
} catch (Exception e) {
e.printStackTrace();
logger.error(e);
request.setAttribute( "error" , e.getClass());
request.setAttribute( "reason" , e.getMessage());
StackTraceElement[] arr=e.getStackTrace();
request.setAttribute( "stackTraceElements" , arr);
return "pages/error/index.jsp" ;
}
