使用HikariCP中TNSNAMES.ORA的设置

我正在尝试迁移到HikariCP以获取应用程序连接池。目前，我想连接到Oracle数据库。

以下是我正在使用的代码：

        HikariConfig hc = new HikariConfig();
        hc.setUsername(username);
        hc.setPassword(password);
        hc.setDataSourceClassName("oracle.jdbc.pool.OracleDataSource");
        hc.addDataSourceProperty("serverName", TNS);
        hc.addDataSourceProperty("portNumber", 1521);
        hc.addDataSourceProperty("driverType", "thin");


        HikariDataSource hds = new HikariDataSource(hc);
        hds.setPoolName("Pool::"+username+"@"+dbName);

TNS变量来自我的配置，并引用服务器上存在的TNSNAMES.ora文件中的设置。

SERVER_1 =
    (DESCRPTION = 
        (ADDRESS_LIST = 
                (ADDRESS = (PROTOCOL = TCP)(HOST = server01.intranet)(PORT = 1521))
        )
        (CONNECTION_DATA = 
                (SERVICE_NAME = SERVER1)
        )
    )

代码失败，出现以下堆栈跟踪：

有没有人有幸用TNS NAME让它在Oracle上运行？

您可以改为使用JDBC URL：

public class LoginPage  
{
    public static WebDriver driver;
    static ResourceLoader loader = new ResourceLoader();

    public static String loginVerify(String username, String password)
    {
        System.out.println("navigated to loginvarify() :: ");
        logger.info("username is "+username);
        logger.info("password is "+password);
        try
        {
          driver.findElement(By.id(loader.getProperty(Constants.UserName))).sendKeys(username);
        }

答案 1 :(得分：0)

设置＆＃34; oracle.net.tns_admin＆＃34;系统属性，以指定TNSNAMES.ORA文件的目录位置。

System.setProperty("oracle.net.tns_admin", "C:\\Development\\TNS_ADMIN");

如果您设置了TNS_ADMIN系统变量，则可以按照以下方式执行此操作

System.setProperty("oracle.net.tns_admin", System.getenv("TNS_ADMIN"));
