java - 无法使用 JDBC 连接远程 oracle 数据库

Question

我似乎能够使用运行 SQL 命令行但不能使用 JDBC 连接到(远程)oracle 数据库。 因此，假设服务器名称为 srv_oracle_prod，数据库名称为 bdcompany.company。在 SQL 命令行中，我可以使用以下命令进行连接:

connect user/password@srv_oracle_prod:1521/bdcompany.company

但是当我尝试

public class TestRealDatabase {

public static void main(String[] args) {


    try {
        Class.forName("oracle.jdbc.driver.OracleDriver");
        con = DriverManager.getConnection("jdbc:oracle:thin:srv_oracle_prod:1521/bdcompany.company", 
                "user", 
                "password");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    }
}

我在 eclipse 中遇到此错误:

java.sql.SQLException: Listener refused the connection with the following error:

我搜索了很多，但找不到任何解决方案，而且我是 Oracle 使用新手。

这是我的tnsnames.ora请求的文件:

XE =

      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = PC-HP-08.COMPANY.local)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME = XE)
        )
      )

    EXTPROC_CONNECTION_DATA =
      (DESCRIPTION =
        (ADDRESS_LIST =
          (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
        )
        (CONNECT_DATA =
          (SID = PLSExtProc)
          (PRESENTATION = RO)
        )
      )

    ORACLR_CONNECTION_DATA = 
      (DESCRIPTION = 
        (ADDRESS_LIST = 
          (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) 
        ) 
        (CONNECT_DATA = 
          (SID = CLRExtProc) 
          (PRESENTATION = RO) 
        ) 
      )

我的 JDBC 精简 URL 通常如下所示:

jdbc:oracle:thin:@SERVER:PORT:SID

在我看来，您正在尝试使用 TNS 名称作为服务器名称。但Oracle瘦驱动程序不使用TNS(据我所知)。

所以我的猜测是您的 JDBC URL 应该如下所示:

jdbc:oracle:thin:@PC-HP-08.COMPANY.local:1521:PLSExtProc
