SpringMvc上传图片，保存在服务器目录下

                 

                首先导入fileupload和commons-io包

                 <dependency>
<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>        在Spring配置文件中配置
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="5242880"/>
</bean>     前端页面的表单如下

<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">
