我正在创建一个应用程序以上传照片以存储在服务器上。但是，通过Post发送请求时出现以下错误：
Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/x-www-form-urlencoded' not supported]
我已经研究了所有内容，看到了一些替代方案，但没有一个能够解决我的问题。我不知道如何提出解决方案。
我的API服务：
@RestController
@RequestMapping(value = "/api")
public class Services {
@Autowired
private PacienteRepository pr;
@GetMapping("/pacientes")
public List<Paciente> listaPaciente() {
return pr.findAll();
}
@RequestMapping(value = "/paciente", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public Paciente cadastraPaciente(@RequestBody Paciente paciente) {
System.out.println(paciente.foto);
return pr.save(paciente);
}
}
我的应用程序：
public class MainActivity extends AppCompatActivity {
public static final String REGISTER_URL = "http://192.168.1.8:8080/api/paciente";
public static final String KEY_IMAGE = "foto";
String foto = "null";
public static final String TAG = "LOG";
private ProgressDialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button enviar = (Button) findViewById(R.id.enviar);
enviar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
registerForms();
}
});
}
public void tirarFoto(View view) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data != null) {
Bundle bundle = data.getExtras();
if (bundle != null) {
Bitmap img = (Bitmap) bundle.get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
img.compress(Bitmap.CompressFormat.JPEG, 100, stream);
foto = Base64.encodeToString(stream.toByteArray(), Base64.DEFAULT);
Toast toast = Toast.makeText(getApplicationContext(), "Foto anexada", Toast.LENGTH_LONG);
toast.show();
}
}
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
}
public void registerForms() {
StringRequest stringRequest = new StringRequest(Request.Method.POST, REGISTER_URL, new Response.Listener<String>() {
@Override

/*if (response.contains("Erro")) {
//progressDialog.dismiss();
Toast.makeText(MainActivity.this, "Erro ao enviar", Toast.LENGTH_LONG).show();
Log.i(TAG, "Lat: " + "Caiu aqui");
} else {*/
//progressDialog.dismiss();
Intent intent = new Intent(MainActivity.this, MainActivity.class);
Toast.makeText(MainActivity.this, "Enviado com sucesso!", Toast.LENGTH_LONG).show();
startActivity(intent);
//}
}
},
new Response.ErrorListener() {
@Override

//progressDialog.dismiss();
Toast.makeText(MainActivity.this, error.toString(), Toast.LENGTH_LONG).show();
Log.i(TAG, "Lat: " + error.getMessage());
Log.i(TAG, "String: " + foto);
}
}) {
@Override
public byte[] getBody() throws AuthFailureError {
String requestBody = ""; //The request body goes in here.
try {
return requestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
return null;
}
}
@Override
protected Map<String, String> getParams() throws AuthFailureError{
Map<String, String> map = new HashMap<String, String>();
map.put("Content-Type","application/x-www-form-urlencoded");
map.put(KEY_IMAGE, "foto1");
return map;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
}
