三、补充点 jersey框架文件上传方式，包含带有参数上传[/b]
通过form表单提交方式进行图片上传
（一）、页面
XML/HTML code?

<`div class="header" style="background-color:#14C2FF;width:400px,height:800px; border:1px red solid;"`>
<`form action="http://localhost:8080/ichanoDeveloper/product/uploadProductImg" method="post" enctype="multipart/form-data"`>
<`p`>
<`input type="file" class="sys_input" name ="productLogo" id=`"productLogo" />
剩productId：<`input type="text" name="productId" value="20" id="productId"/><br /> `
</`p`>
<`input type="submit" value="上传" /> `
</`form`>
</`div`>
