Hi mọi người, mình đang gặp lỗi không upload được file ảnh từ android studio (máy thật) xuống wep api spring boot , nó cứ báo lỗi failed to connect to localhost/127.0.0.1:8080, mình đã test gửi file ảnh từ web client xuống thì vẫn ok nhưng bên android thì failed. Dưới đây là code của mình.
class ApiUploadController của Spring Boot
package com.myclass.api.controller;
import java.io.File;
import java.io.IOException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import com.myclass.repository.PhotoRepository;
import com.myclass.repository.UserRepository;
@RestController
@RequestMapping("/api/file")
public class ApiUploadController {
@Autowired
UserRepository userRepository;
@Autowired
PhotoRepository photoRepository;
@PostMapping("/upload")
//@CrossOrigin(origins = "*")
public Object post(@RequestPart(name = "file") MultipartFile file) {
try {
// System.out.println("Email: " + email);
// System.out.println("Password: " + password);
// Lấy đường dẫn tuyệt đối của thư mục chứa file upload
// String folderPath = request.getServletContext().getRealPath("/upload/");
//String folderPath = System.getProperty("user.dir");
String folderPath = "C:\\Users\\HaiApple.com\\Desktop\\workspace WebCameraAPI SpringBoot\\WebCameraAPI\\src\\main\\resources\\static";
folderPath += "\\upload\\";
// Sử dụng đối tượng File của java.io để kiểm tra thư mục
File dir = new File(folderPath);
System.out.println("Folder save image: " + folderPath);
// Nếu chưa tồn tại thư mục upload thì tạo mới
if (!dir.exists()) {
dir.mkdir();
}
// Lấy ra tên file vừa gửi từ client lên
String fileName = file.getOriginalFilename();
// Sử dụng đối tượng File của java.io để lưu file
File filePath = new File(folderPath + fileName);
System.out.println("filepath: " + filePath);
// User user = null;
// user = userRepository.findByEmail(email);
//
// if (user == null) {
// System.out.println("Lỗi null");
// return new ResponseEntity<String>(HttpStatus.BAD_REQUEST);
// }
// if (user != null) {
// System.out.println("User in database: " + user.toString());
// if (!user.getPassword().equals(password)) {
// return new ResponseEntity<String>(HttpStatus.BAD_REQUEST);
// }
// }
// Sử dụng phương thức transferTo của MultipartFile để lưu file xuống thư mục
file.transferTo(filePath);
//int id=photoRepository.findAll().size();
//System.out.println("Length photo: " + id);
// int userIdUpload= user.getId();
// Photo photo = new Photo(fileName,filePath.toString(),userIdUpload);
// photoRepository.save(photo);
System.out.println("Đã save file");
return new ResponseEntity<String>("/upload/" + fileName, HttpStatus.OK);
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return new ResponseEntity<String>(HttpStatus.BAD_REQUEST);
}
}
Ở Android Studio mình search trên mạng thấy bảo xài retrofit 2 nên mình khai báo
implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.google.code.gson:gson:2.6.1'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'

interface UploadAPI ở Android Studio
package com.example.camerascan;
import okhttp3.MultipartBody;
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.http.Multipart;
import retrofit2.http.POST;
import retrofit2.http.Part;
public interface UploadAPIs {
// @Multipart
// @POST("/upload")

// @Field("email") String email,

@Multipart
@POST("upload")
Call<ResponseBody> upload(@Part MultipartBody.Part file);
}
class NetworkClient trong Android Studio
package com.example.camerascan;
import android.content.Context;
import okhttp3.OkHttpClient;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class NetworkClient {
//private static final String BASE_URL = "http://localhost:8080/api/file/";
private static final String BASE_URL = "http://127.0.0.1:8080/api/file/";
private static Retrofit retrofit;
public static Retrofit getRetrofitClient(Context context) {
if (retrofit == null) {
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.build();
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(okHttpClient)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
Trong Main Activity thì mình tạo Button Upload đến Server
btnUpload.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Retrofit retrofit = NetworkClient.getRetrofitClient(MainActivity.this);
UploadAPIs uploadAPIs = retrofit.create(UploadAPIs.class);
//Create a file object using file path
File file = new File(imgPath);
if (!file.exists()) {
System.out.println("CHUA TON TAI");
file.mkdir();
}
Toast.makeText(getApplication(), "onclick btnUpload: " + imgPath, Toast.LENGTH_SHORT).show();
System.out.println("onclick btnUpload: " + imgPath);
System.out.println("directory file upload: " + file.getAbsolutePath());
// Create a request body with file and image media type
//RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
RequestBody requestFile = RequestBody.create(MediaType.parse("*/*"), file);
// Create MultipartBody.Part using file request-body,file name and part name
System.out.println("Name file image: " + file.getName());
MultipartBody.Part part = MultipartBody.Part.createFormData("file", file.getName(), requestFile);
//Create request body with text description and text media type
//RequestBody description = RequestBody.create(MediaType.parse("text/plain"), "image-type");
//
Call call = uploadAPIs.upload(part);
call.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
if (response.isSuccessful()) {
Toast.makeText(MainActivity.this, "Image uploaded success", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
Toast.makeText(MainActivity.this, "ERROR " + t.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
});
