SpringMVC+ExtJS3.x实现文件上传

第一步：

配置文件applicationContext.xml中添加解析类bean

 <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
  <property name="defaultEncoding" value="UTF-8"></property>
 </bean>

控制器实现：

@Controller
public class FileController {
 
 @RequestMapping("/upload")
 public String doUpload(@RequestParam(value = "F_FileType", required = false) String sType,HttpServletRequest request){
  MultipartHttpServletRequest fileRequest = (MultipartHttpServletRequest) request; 
  MultipartFile file = fileRequest.getFile("F_PicPath");  
  String path = request.getSession().getServletContext().getRealPath("upload")+"\\"+sType+"\\";
  String fileName = file.getOriginalFilename();
  
  File targetFile = new File(path, fileName);
  if (!targetFile.exists()){
   targetFile.mkdirs();
  }
  try{
   file.transferTo(targetFile);
  }catch(Exception e){
   e.printStackTrace();
  }
  return "result";
 }
}

ExtJS 界面调用：

在FormPanel中添加属性 fileUpload : true,

提交需要用form提交：

function doSubmitFile(){
 //var fileNameObj = Ext.getCmp('F_PicPath');
 var fileNameObj = Ext.getCmp('F_PicPath');
 housedoor_center_form.getForm().submit({
  url : "upload.do",
  waitMsg : '正在保存数据...',
  params:{
   "F_FileType":'1'
  },
  success : onAddSuccess,
  failure : onFailure
 });
}
