Android中Post Request Spring Boot Rest服务的I/O错误

Question

>

我正在做一个小的android应用程序。因为我使用Http Rest调用将用户输入的信息存储到本地数据库。

服务没有问题，工作正常，我在浏览器和邮递员中测试过，我可以通过邮递员客户端执行CRUD操作。

但当我尝试发布或从Android获取时，它会抛出错误，如POST方法连接拒绝时的I/O错误。

我不知道这是什么原因。

下面是我在Android中的代码。

此代码用于GET请求。

public class Result extends appcompattivity{String id；Login Login=new Login（）；final String url=“http://192.168.1.189:9001/Login”；//List Login=new arraylist<>()；Button注销；TextView nameTv,ageTv,emailTv,usernametv；String NAME,AGE,EMAIL,username；

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_result);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
   // Intent intent=getIntent();
   // ID=intent.getStringExtra("ID");
    // new HttpGetTask().execute();

    logout = (Button) findViewById(R.id.buttonLogout);
    nameTv = (TextView) findViewById(R.id.nameTextView);
    ageTv = (TextView) findViewById(R.id.ageTextView);
    emailTv = (TextView) findViewById(R.id.emailTextView);
    usernameTv = (TextView) findViewById(R.id.UsernameTextView);
    nameTv.setText(NAME);
    ageTv.setText(AGE);
    emailTv.setText(EMAIL);
    usernameTv.setText(USERNAME);
    new HttpRequestTask().execute();


    logout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent logoutintent = new Intent(Result.this, MainActivity.class);
            startActivity(logoutintent);
        }
    });


}

private class HttpRequestTask extends AsyncTask<Void, Void, Login> {


    @Override
    protected Login doInBackground(Void... params) {
        try {


            //  final String url = "http://192.168.1.213:9001/consumer/local/64";

            RestTemplate restTemplate = new RestTemplate();
            Login lg = restTemplate.getForObject(url, Login.class);
           // NAME=lg.getName().toString();
            Log.d("", "doInBackground:++++++++++++++++++++++ "+NAME);
            return lg;

        } catch (Exception e) {
            Log.e("MainActivity", e.getMessage(), e);

        }
        return null;
    }

下面的代码用于POST请求。

public class Register extends AppCompatActivity{Button buttonregister；public String id；TextView editId,editName,editAge,editEmail,editUsername,editpassword；private String Name,Age,Email,Username,editpassword；Login Login=new Login()；

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_register);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    editId=(TextView)findViewById(R.id.editId);

    editName=(TextView)findViewById(R.id.editName);
    editAge=(TextView)findViewById(R.id.editAge);
    editEmail=(TextView)findViewById(R.id.editEmail);
    editUsername=(TextView)findViewById(R.id.editUsername);
    editPassword=(TextView)findViewById(R.id.editPassword);
    buttonRegister = (Button)findViewById(R.id.buttonRegister);

    buttonRegister.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            Toast.makeText(Register.this, "Registration Successful", Toast.LENGTH_SHORT).show();
            Name = editName.getText().toString();

            Age = editAge.getText().toString();
            Email = editEmail.getText().toString();
            Username = editUsername.getText().toString();
            Password = editPassword.getText().toString();

            Log.d("???????????", "onClick:------------> " + Name);
            Log.d("???????????", "onClick:------------> " + ID);
            Log.d("???????????", "onClick:------------> " + Age);
            Log.d("???????????", "onClick:------------> " + Email);
            Log.d("???????????", "onClick:------------> " + Username);
            Log.d("???????????", "onClick:------------> " + Password);
            new HttpPostTask().execute();
            Intent regintent = new Intent(Register.this, Result.class);
            //regintent.putExtra("ID",1);
            startActivity(regintent);

            /*Intent regintent = new Intent(Register.this, Result.class);
            startActivity(regintent);*/


        }
    });

public class HttpPostTask extends AsyncTask<Void,Void,Login>{

    @Override
    protected Login doInBackground(Void... params) {
