英文:
Function which returns connection variable
问题
在我的Java应用程序中，我有这样的代码：
private static OracleDataSource oracleDatasource;
public static OracleConnection getConnection() throws SQLException
{
final OracleConnection conn = (OracleConnection) oracleDatasource.getConnection("user", "password");
return conn;
}
我想要在Postgres JDBC中编写一个等效的函数。我知道我可以使用这行代码来定义数据源：
private static PGSimpleDataSource postgresDatasource;
但是我应该如何定义并返回类似Oracle中的连接变量呢？
英文:
In my Java application I have such code:
private static OracleDataSource oracleDatasource;
public static OracleConnection getConnection() throws SQLException
{
final OracleConnection conn = (OracleConnection) oracleDatasource.getConnection("user", "password");
return conn;
}
I would like to write equivalent of such function in Postgres JDBC. I know that I could use this line
private static PGSimpleDataSource postgresDatasource;
to define data source. But how can I define and return connection variable like it was in Oracle?
