smartupload实现多图上传

jsp页面

<form class="form-inline definewidth m20" action="<%=basePath %>upload" method="post" enctype="multipart/form-data">
    图片一：<input type="file" name="myfile1">名称：<input type="text" name="title"><br>
    图片二：<input type="file" name="myfile2">名称：<input type="text" name="title"><br>
    图片三：<input type="file" name="myfile3">名称：<input type="text" name="title"><br>
    图片四：<input type="file" name="myfile4">名称：<input type="text" name="title"><br>
 <input type="submit" value="提交">
</form>

web.xml配置

 <servlet>
    <servlet-name>Upload</servlet-name>
    <servlet-class>com.test.servlet.UploadServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>Upload</servlet-name>
    <url-pattern>/upload</url-pattern>
  </servlet-mapping>

这样就利用smartupload插件实现了多图上传，并将信息插入数据库的功能了
