Question

你好，我有问题

我是第一次尝试使ant命令成功运行，但是我遇到了一些问题。

当我在项目文件夹中的cmd ant上输入数字时，prject会正确编译，然后当我必须连接到我的postgres服务器时，它崩溃并说： DBManager，SignIn，找不到适合jdbc的驱动程序：postgresql：//127.0.0.1：5432 / dbName

在这里您可以看到我的build.xml文件（但我不确定错误是否在那里）

<?xml version="1.0" encoding="UTF-8"?>

-<project basedir="." default="execute" name="BuildReader">

<!-- Config File -->


<!-- - - - - - - - - - - - - - - - - - - - -->


<!-- DON'T TOUCH HERE -->


<property name="path" value="./"/>

<property name="name" value="reader"/>

<property name="source_dir" value="."/>

</path>

</target>

</target>


-<target name="execute" depends="jar">

</target>

</project>

正如我所说，当我在项目文件夹中输入ant时程序就启动了，但是当我输入服务器凭据时却出现了此错误（程序不会崩溃，但不会登录到服务器）

在这里您可以看到对服务器的连接

private void setup() throws SQLException {
        Scanner scan = new Scanner(System.in);
        while ((conn == null) || (conn.isClosed())) {

            System.out.println("Insert host");
            String host = scan.nextLine();
            System.out.println("Insert Username");
            String user = scan.nextLine();
            System.out.println("Insert Password");
            String psw = scan.nextLine();

            String connectionStringU = "jdbc:postgresql://" + host + ":5432/dbSeatIn";

            // conn = DriverManager.getConnection(connectionString, userName, password);
            try {
                conn = DriverManager.getConnection(connectionStringU, user, psw);
            } catch (Exception e) {
                Logger.WriteError(e, "sas", "sssss");
                try {
                    PulisciConsole();
                } catch (IOException e1) {

                }
                System.out.println("Connection failed");
                Logger.WriteError(e, "DBManager", "SignIn");
            }
        }
        System.out.println("Connection up");

        System.out.println("Loading setUpList");

        CommonList.Updatesip(conn);
        CommonList.UpdateCourse(conn);
        CommonList.UpdateSubj(conn);

        System.out.println("List loaded");

    }

有人可以帮助我找出我做错了什么地方吗？
