我是靠谱客的博主年轻马里奥，这篇文章主要介绍springmvc服务端+android客户端的文件上传，现在分享给大家，希望可以做个参考。

一、Springmvc服务端

1.引入文件上传的JAR包commons-fileupload-1.2.jar，commons-io-1.3.2.jar.

2.

<beanid="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver"></bean>

</beans>

3.服务端

1）构建回传类

Result.java

ackage org.linfeng.action;
import org.springframework.stereotype.Component;

@Component
public class Result {
	private String path;
	private String code;
	private String message;
	public String getPath() {
		return path;
	}
	public void setPath(String path) {
		this.path = path;
	}
	public String getCode() {
		return code;
	}
	public void setCode(String code) {
		this.code = code;
	}
	public void setMessage(String message) {
		this.message = message;
	}
	public String getMessage() {
		return message;
	}
}

2）构建控制器

复制代码

@Controller

public class UploadController {

@Resource

privateResult result;

@RequestMapping("/mobile/uploadfile")

@ResponseBody      //把回传类转换成json

public   ResultuploadPhone(@RequestParam(value="file",required=false)MultipartFilefile,HttpServletRequest request) throws IllegalStateException, IOException{

Stringpath=uploadFile(file, request);

result.setCode("200");

result.setPath(path);

result.setMessage("上传成功");

returnresult;

}

/**

* 上传

* @param file

* @param request

* @return

* @throws IOException

privateString  uploadFile(MultipartFile file,HttpServletRequest request)

throwsIOException {

Stringpath=request.getSession().getServletContext().getRealPath("upload");

StringfileName=file.getOriginalFilename();

FiletargetFile=new File(path,fileName);

if(!targetFile.exists()){

targetFile.mkdirs();

}

file.transferTo(targetFile);

//               request.setAttribute("filePath",targetFile.getAbsolutePath());

return    targetFile.getAbsolutePath();

}

@Controller

public class UploadController {

         @Resource

         privateResult result;

 

         @RequestMapping("/mobile/uploadfile")

         @ResponseBody      //把回传类转换成json

         public   ResultuploadPhone(@RequestParam(value="file",required=false)MultipartFilefile,HttpServletRequest request) throws IllegalStateException, IOException{

                   Stringpath=uploadFile(file, request);

                   result.setCode("200");

                   result.setPath(path);

                   result.setMessage("上传成功");

                   returnresult;

         }

         /**

          * 上传

          * @param file

          * @param request

          * @return

          * @throws IOException

          */

         privateString  uploadFile(MultipartFile file,HttpServletRequest request)

                            throwsIOException {

                   Stringpath=request.getSession().getServletContext().getRealPath("upload");

                   StringfileName=file.getOriginalFilename();

                   FiletargetFile=new File(path,fileName);

                   if(!targetFile.exists()){

                            targetFile.mkdirs();

                   }

                   file.transferTo(targetFile);

//               request.setAttribute("filePath",targetFile.getAbsolutePath());

                   return    targetFile.getAbsolutePath();

         }

}

二、android客户端

1.导入上传需要的JAR包httpmime-4.1.1.jar

2.写一个工具类使用HttpClient

复制代码

public class AndroidUploadFile {

/**

* @param filePath 文件地址

* @param urlServer  服务器的地址

* @return

* @throws IOException

* @throws ClientProtocolException

publicstatic  String uoloadFile(StringfilePath,String urlServer) throws ClientProtocolException, IOException{

//使用HttpClient

HttpClienthttpClient=new DefaultHttpClient();

//必须设置请求的协议

httpClient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,HttpVersion.HTTP_1_1);

//设置http post请求

HttpPost  httpPost=new HttpPost(urlServer);

//构建上传的文件的实体

MultipartEntity  multipartEntity=new MultipartEntity();

//构建文件的File的对象

Filefile=new File(filePath);

//添加文件的

ContentBodycontentBody=new FileBody(file);

multipartEntity.addPart("file",contentBody);//<input type="file" name="file">

//把请求实体设置到HttpPost

httpPost.setEntity(multipartEntity);

//执行这个请求

HttpResponseresponse=httpClient.execute(httpPost);

//通过响应取到状态行

StatusLinestatusLine= response.getStatusLine();

//通过状态码去判断

if(statusLine.getStatusCode()==HttpStatus.SC_OK){

HttpEntity  entity=response.getEntity();

Stringresult=EntityUtils.toString(entity);

Log.i("TAG","*******"+result);

}else{

Log.i("TAG","请求出了问题");

}

returnnull;

}

public class AndroidUploadFile {

         /**

          * @param filePath 文件地址

          * @param urlServer  服务器的地址

          * @return

          * @throws IOException

          * @throws ClientProtocolException

          */

         publicstatic  String uoloadFile(StringfilePath,String urlServer) throws ClientProtocolException, IOException{

                   //使用HttpClient

                   HttpClienthttpClient=new DefaultHttpClient();

                   //必须设置请求的协议

                   httpClient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,HttpVersion.HTTP_1_1);

                   //设置http post请求

                   HttpPost  httpPost=new HttpPost(urlServer);

                   //构建上传的文件的实体

                   MultipartEntity  multipartEntity=new MultipartEntity();

                   //构建文件的File的对象

                   Filefile=new File(filePath);

                   //添加文件的

                   ContentBodycontentBody=new FileBody(file);

                   multipartEntity.addPart("file",contentBody);//<input type="file" name="file">

                   //把请求实体设置到HttpPost

                   httpPost.setEntity(multipartEntity);

                   //执行这个请求

                   HttpResponseresponse=httpClient.execute(httpPost);

                   //通过响应取到状态行

                   StatusLinestatusLine= response.getStatusLine();

                   //通过状态码去判断

                   if(statusLine.getStatusCode()==HttpStatus.SC_OK){

                            HttpEntity  entity=response.getEntity();

                            Stringresult=EntityUtils.toString(entity);

                            Log.i("TAG","*******"+result);

                   }else{

                            Log.i("TAG","请求出了问题");

                   }

                   returnnull;

         }

}

3.在UI线程调用工具类方法，注意，耗时操作必须另外开启一个工作线程执行
