我正在尝试使用JDBC连接到oracle数据库。
以下是代码::
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();
}
}
}
如果密码具有#@等特殊字符,则上述代码无效。它使用普通密码。
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(如@
,/
等)中有特殊字符时,我们必须将其包含在双引号中,例如,如果密码为{{1}我们在sqlplus中连接为p@ssword
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
username/"p@ssword"@database
到
String pwd = "s@novi123";
我不是Java专家,只是猜测角色应该是String pwd = "\"s@novi123\"";

一个简单的代码看起来像这样......当您使用瘦驱动程序时,您不需要复制来自tnsnames.ora的所有值。
Class.forName("oracle.jdbc.OracleDriver");
Properties properties = new Properties();
properties.setProperty("user", username);
properties.setProperty("password", password);
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@<DB_HOST>:<PORT>:<SID>, properties);
即。 JDBC:预言:瘦:@ 192.168.20.145:1521:oradg
