我正在开发一个android应用程序，从azure sql数据库获取数据。
应用程序在尝试获取数据时引发异常（sqlexception）。显示的错误消息是 Network error IOException: SSL handshake aborted: ssl=0x9a56a8e8: I/O error during system call, Broken pipe . 不提取任何数据。
然而，只有在使用安卓10及更低版本时才会发生这种情况，并且在安卓11中工作并成功获取数据。
我已将我的代码张贴在下面：

public class MainActivity extends AppCompatActivity {

    public TextView textView;
    public Button button;
    public Connection con;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = findViewById(R.id.textView);
        button = findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                CheckLogin checkLogin = new CheckLogin();
                checkLogin.execute("");
            }
        });
    }

    public class CheckLogin extends AsyncTask<String, String, String> {
        String z = "";
        Boolean isSuccess = false;
        String name1 = "";

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        @Override
        protected void onPostExecute(String r) {
            Toast.makeText(MainActivity.this, r, Toast.LENGTH_LONG).show();
            if (isSuccess) {
                textView = findViewById(R.id.textView);
                textView.setText(name1);
            }
        }

        @Override
        protected String doInBackground(String... params) {
            try {
                con = connectionclass();
                if (con == null) {
                    z = "Check your internet access!";
                } else {
                    //String query = "select * from Users";
                    Statement stmt = con.createStatement();
                    //Check what databases are available (check if connecting to correct place
                    Log.e("Error",stmt.getConnection().getCatalog());
                    ResultSet rs = stmt.executeQuery("SELECT * FROM Users");
                    // try while???
                    if (rs.next()) {
                        name1 = rs.getString("Name"); // Name is a column in our Users table
                        z = "query successful";
                        isSuccess = true;
                        con.close();
                    } else {
                        z = "invalid query";
                        isSuccess = false;
                    }
                }
            } catch (Exception exception) {
                isSuccess = false;
                z = exception.getMessage();
                Log.d("sql error", z);
            }
            return z;
        }
    }

    @SuppressLint("NewApi")
    public Connection connectionclass() {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
        Connection connection = null;
        try {
            Class.forName("net.sourceforge.jtds.jdbc.Driver");

            String hostName = "azuretestappandroid";
            String dbName = "AppTestingDatabase";
            String user = "Tester@azuretestappandroid";
            String userPwd = "XXX";
            String connectionURL = String.format("jdbc:jtds:sqlserver://%s.database.windows.net:1433/%s;user=%s;encrypt=true;hostNameInCertificate=*.database.windows.net;loginTimeout=30;ssl=required",hostName,dbName,user,userPwd);

            connection = DriverManager.getConnection(connectionURL,user,userPwd);
        } catch (SQLException exception) {
            Log.e("error here 1: ", exception.getMessage());
        } catch (ClassNotFoundException exception) {
            Log.e("error here 2: ", exception.getMessage());
        } catch (Exception exception) {
            Log.e("error here 3: ", exception.getMessage());
        }
        return connection;
    }
}

我确实理解jtds库已经过时，因此如果您对如何向azure sql数据库读写数据有任何建议，我们将不胜感激。
