Question

我正在尝试使用Android Studio通过移动应用程序连接到我的Azure sql数据库。

String connectionURL = "jdbc:sqlserver://****.database.windows.net:1433;database=****;user=****@****;password=*****;encrypt=false;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30";

public void connect(){

    Connection connection = null;

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);

    try {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

        connection = DriverManager.getConnection(connectionURL);

    }
    catch (Exception e) {
        e.printStackTrace();
    }

这是我在Azure上连接数据库的代码。已导入正确的JDBC驱动程序，我使用正确的用户名/密码（在***中标记）。我不断收到有关SSL的相同错误，如下所示 -

我查看了很多答案和文件，但我似乎无法解决问题。如何使用SSL连接到Azure数据库？

您可以尝试使用JTDS驱动程序

main_data_a = zeros(10000000, 3);
main_data_b = zeros(10000000, 3);
main_data_c = ones(10000000, 1);
for i=1:1:10000000
    try
        to_load=sprintf('data/output%d.mat',i);
        load(to_load);
    catch

    end;
    if sum(a) ~= 0 
        main_data_a(i,:) = a;
        main_data_b(i,:) = b;
        main_data_c(i,:) = c;
    end;
end;

无法使用JDBC连接到Azure sql数据库 - 使用SSL时出错
