SpringMVC+Volley实现Android端上传文件

Android端使用的是Volley的Request基类，实现它的几个方法，以拼接表单的方式来上传文件

服务器端则是采用Spring框架来接收文件。

一、Android：三个类：MainActivity，PostRequest，UploadFileRequest.

1.PostRequest继承自Request,实现它的deliverResponse和parseNetworkResponse以及getParams三个方法，

构造函数为

public PostRequest(String url,Mapparams, ResponseListener listener){...}

2.UploadFileRequest继承自PostRequest，实现其getBody()和getBodyContentType()方法，getBody来拼接表单数据，getBodyContentType用来返回表单类型：

return "multipart/form-data;boundary=------8d74g45h";

构造函数为

public UploadFileRequest(String url, ListfileList, ResponseListener listener){...}

3.在MainActivity中调用UploadFileRequest，并添加到Volley队列中。

uploadFileRequest = new UploadFileRequest(url, fileForms, new ResponseListener() {
    @Override
    public void onErrorResponse(VolleyError volleyError) {
        Toast.makeText(MainActivity.this, "上传失败", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onResponse(Object o) {
        Toast.makeText(MainActivity.this, "上传成功", Toast.LENGTH_SHORT).show();
    }
});

Volley.newRequestQueue(MainActivity.this).add(uploadFileRequest);
 
  
二、服务器端：
 
  
@Controller
public class UploadController {

    @RequestMapping("uploadImage")
    //@ResponseBody
    public void addImage(HttpServletRequest request) throws IllegalStateException, IOException{
        MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest) request;
        MultipartFile file = multipartHttpServletRequest.getFile("uploadfile");
        if(!file.getOriginalFilename()==null){
            File targetFile = new File("F:/789.png");
            file.transferTo(targetFile);
        }

    }
 
  
 
  
 
  使用MultipartHttpServletRequest 的时候要记得在spring配置文件中添加Multipart的解析器： 
  
 
   
  
@Controller
public class UploadController {

    @RequestMapping("uploadImage")
    //@ResponseBody
    public void addImage(HttpServletRequest request) throws IllegalStateException, IOException{
        MultipartHttpServletRequest multipartHttpServletRequest = (MultipartHttpServletRequest) request;
        MultipartFile file = multipartHttpServletRequest.getFile("uploadfile");
        if(!file.getOriginalFilename()==null){
            File targetFile = new File("F:/789.png");
            file.transferTo(targetFile);
        }

    }
 
  
 
   
  
 
  这样就完成了文件上传的操作。
