在HikariCP中使用来自TNSNAMES.ORA的设置

我正在尝试为我的应用程序连接池迁移到HikariCP。目前，我想连接到Oracle数据库。在HikariCP中使用来自TNSNAMES.ORA的设置

这里是我使用的代码：

 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的变量来自于我的配置，并引用存在于服务器上的TNSNAMES.ORA一个设置文件。

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：

是否任何人有任何运气，使其在Oracle工作与TNS NAME？

看起来它想要一个实际的主机名，而不是名称定义TNSNAMES条目。尝试将'TNS'设置为'server01.hostname'而不是'SERVER_1'。 – schtever

尝试IP而不是server01.intranet – user7294900

这些信息都已存储在tnsnames.ora中，其中包含所有数据库服务器的所有信息。此文件的目的是为了避免手动编写IP或DNS条目 – 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")

它的确行得通，即使我只是简单地把 hc。 setJdbcUrl（ “JDBC：预言：瘦：@ Server_1的”）。不知怎的，用这种方法，我可以使用tnsnames.ora中的设置，如果不是从数据源配置 – Shade

那么这是一个更好的解决方案？你接受这个建议吗？ – user7294900

我接受它，因为我没有任何其他解决方案，它确实工作。不过，我希望我可以使用没有直接写入jdbc url的数据源。我在github上打开了一个问题，谁知道:) – Shade

设置“oracle.net.tns_admin”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");

如果你有TNS_ADMIN系统变量设置，你可以做到这一点在下面的方式

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