首先导入fileupload和commons-io包
<dependency>在Spring配置文件中配置
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">前端页面的表单如下
<property name="maxUploadSize" value="5242880"/>
</bean>
<form method="post" class="form-x" action="addIndent" enctype="multipart/form-data"> <div class="form-group"> <div class="label"> <label>商品名称：</label> </div> <div class="field"> <input type="text" class="input" name="commodityName" value="" /> <div class="tips"></div> </div> </div> <div class="form-group"> <div class="label"> <label>商品首页图片：</label> </div> <a href="javascript:;" class="file"> 选择文件 <input id="imagetop" type="file" name="imagetop" onchange="change(imagetop);"> </a> </div> <div class="form-group"> <div class="label"> <label>商品图片1：</label> </div> <a href="javascript:;" class="file"> 选择文件 <input type="file" name="imagetwo" > </a> </div> <div class="form-group"> <div class="label"> <label>商品图片2：</label> </div> <a href="javascript:;" class="file"> 选择文件 <input type="file" name="imagethree" > </a> </div> <div class="form-group"> <div class="label"> <label>商品价格：</label> </div> <div class="field"> <input type="text" class="input" name="price" value="" /> </div> </div> <div class="form-group"> <div class="label"> <label>商品描述：</label> </div> <div class="field"> <textarea class="input" name="description" style="height:80px"></textarea> <div class="tips"></div> </div> </div> <div class="form-group"> <div class="label"> <label>商品折扣：</label> </div> <div class="field"> <input type="text" class="input" name="discount" value="" /> <div class="tips"></div> </div> </div> <div class="form-group"> <div class="label"> <label></label> </div> <div class="field"> <button class="button bg-main icon-check-square-o" type="submit"> 提交</button> </div> </div> </form>控制器为
