在HikariCP中使用來自TNSNAMES.ORA的設置

我正在嘗試爲我的應用程序連接池遷移到HikariCP。目前，我想連接到Oracle數據庫。在HikariCP中使用來自TNSNAMES.ORA的設置

這裏是我使用的代碼：

 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的變量來自於我的配置，並引用存在於服務器上的TNSNAMES.ORA一個設置文件。

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

代碼失敗，出現以下堆棧跟蹤：

是否任何人有任何運氣，使其在Oracle工作與TNS NAME？

看起來它想要一個實際的主機名，而不是名稱定義TNSNAMES條目。嘗試將'TNS'設置爲'server01.hostname'而不是'SERVER_1'。 – schtever

嘗試IP而不是server01.intranet – user7294900

這些信息都已存儲在tnsnames.ora中，其中包含所有數據庫服務器的所有信息。此文件的目的是爲了避免手動編寫IP或DNS條目 – Shade

你可以用JDBC URL，而不是工作：

dataSource.setDriverClassName("oracle.jdbc.driver.OracleDriver"); 
dataSource.setJdbcUrl("jdbc:oracle:thin:@server01.intranet:1521/SERVER1")

它的確行得通，即使我只是簡單地把 hc。 setJdbcUrl（「JDBC：預言：瘦：@ Server_1的」）。不知怎的，用這種方法，我可以使用tnsnames.ora中的設置，如果不是從數據源配置 – Shade

那麼這是一個更好的解決方案？你接受這個建議嗎？ – user7294900

我接受它，因爲我沒有任何其他解決方案，它確實工作。不過，我希望我可以使用沒有直接寫入jdbc url的數據源。我在github上打開了一個問題，誰知道:) – Shade

設置「oracle.net.tns_admin」系統屬性以指定TNSNAMES.ORA文件的目錄位置。

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

如果你有TNS_ADMIN系統變量設置，你可以做到這一點在下面的方式

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