法一：
1 OracleDataSource ds = new OracleDataSource();
2 ds.setDriverType("oci");
3 ds.setNetworkProtocol("tcp");
4 ds.setServerName("10.3.5.78");
5 ds.setPortNumber(1522);
6 ds.setDatabaseName("orcl");
7 ds.setUser("scott");
8 ds.setPassword("tiger");
法二：
OracleDataSource ds = new OracleDataSource();
ds.setDriverType("oci");
ds.setTNSEntryName("orcl");
ds.setUser("scott");
ds.setPassword("tiger");
法三：
OracleDataSource ds = new OracleDataSource();
ds.setURL("jdbc:oracle:oci:@orcl");
ds.setUser("scott");
ds.setPassword("tiger");
If you are using the JDBC Thin or OCI driver, then note the following:
■A URL setting can include settings for user and password, as in the following example, in which case this takes precedence over individual user and password property settings:
jdbc:oracle:thin:scott/tiger@localhost:1521:orcl
■Settings for user and password are required, either directly through the URL setting or through the getConnection call. The user and password settings in a getConnection call take precedence over any property settings.
■If the url property is set, then any tnsEntry, driverType, portNumber, networkProtocol, serverName, and databaseName property settings are
ignored.
■If the tnsEntry property is set, which presumes the url property is not set, then any databaseName, serverName, portNumber, and networkProtocol settings are ignored.
■If you are using an OCI driver, which presumes the driverType property is set to oci, and the networkProtocol is set to ipc, then any other property settings are ignored.
