我真的不知道下面的代码有什么问题。我能够从 SQL 开发人员连接，但通过 JDBC 它给出了异常。

package com.shruti.jdbc;
import java.sql.Connection;
import java.sql.DriverManager;

public class ReadData {
    
    public static void main(String[] args) throws Exception {
        
        Class.forName("oracle.jdbc.driver.OracleDriver"); 
        Connection con=DriverManager.getConnection("jdbc:oracle:thin:@100.92.25.90:1521:PDB1.pvtsub1.xxxxx0011iad.oraclevcn.com","gotapps","WElcome***#11");
        
    }

}

我在 SQL DEveloper 中提到的相同连接细节并且它正在工作。

正确的 jbdc 网址是：

“jdbc:oracle:thin:@100.92.25.90:1521/PDB1.pvtsub1.xxxxx0011iad.oraclevcn.com”

您需要将1521和PDB1之间的“:”更改为“/”
