我正在尝试编写一个非常简单的GUI应用程序,用于将一些记录插入数据库,并读回一些记录(没什么特别的,只有1个表有3行,没有关系).来源...

package EntryProg;
import java.sql.*;
import com.microsoft.sqlserver.jdbc.*;



public class CourseDataEntryHandler
{
    private Connection connect;
    private CallableStatement callState;
    private ResultSet rSet;
    private SQLServerDataSource dSource;

    public CourseDataEntryHandler()
    {
        rSet = null;
        callState = null;

        dSource = new SQLServerDataSource();
        dSource.setUser(REDACTED);
        dSource.setPassword(REDACTED);
        dSource.setServerName(REDACTED);
        dSource.setPortNumber(REDACTED);
        dSource.setDatabaseName(REDACTED);
        dSource.setEncrypt(true);
        dSource.setTrustServerCertificate(true);
        try
        {

这里错了

            connect = dSource.getConnection();

结束错误

        }
        catch (SQLServerException e)
        {
            //TODO Figure out how to handle -- logging for now, console
            do
            {
                System.out.println(e.getErrorCode());
                System.out.println(e.getMessage());
                System.out.println(e.getSQLState());
                e = (SQLServerException) e.getNextException();
            } while (e != null); …
