java - 如果密码包含特殊字符，则无法使用 JDBC 连接到 oracle 数据库

Question

我正在尝试使用 JDBC 连接到 oracle 数据库。

代码如下:

public class OraclePwdTest {
static{
    try {           
        Class.forName("oracle.jdbc.OracleDriver");

    } catch (ClassNotFoundException e) {            
        e.printStackTrace();
    }
}
public static void main(String[] args) {
    // TODO Auto-generated method stub
    String ip ="192.168.20.145";
    String sid = "oradg";
    int port = 1521;
    String user = "sys";
    String pwd = "s@novi123";
    Connection conn = null;
    String url = "jdbc:oracle:thin:"+"(DESCRIPTION =" + 
            "(ADDRESS_LIST =" + 
            "(ADDRESS = (PROTOCOL = TCP)(HOST = "+ ip +")" +  
            "(PORT = " + port + "))" +  
                ")" + 
            "(CONNECT_DATA = (SRVR=DEDICATED) " + 
            "(SID = " + sid + 
            "))" + 
            ")"; 
    java.util.Properties prop = new java.util.Properties ();

    prop.put ("user", user); 
    prop.put ("password", pwd);
    prop.put ("internal_logon", "sysdba");
    try {
        conn = DriverManager.getConnection(url,prop);

        System.out.println("Connected");
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

如果密码有像#@这样的特殊字符...那么上面的代码就不起作用了。它适用于普通密码。

我收到以下错误消息::

java.sql.SQLException: ORA-01017: 用户名/密码无效；登录被拒绝

请帮我解决这个问题。

当用户名、密码或连接字符串中有特殊字符如@、/等时，我们必须将其包含在双引号中，例如，如果密码是 p@ssword 我们在 sqlplus 中连接为 username/"p@ssword"@database

您可以在 java 中尝试使用转义字符将密码括在双引号中，尝试更改

String pwd = "s@novi123";

到

String pwd = "\"s@novi123\"";

我不是java专家，只是猜测scape字符应该是\ ;-)
