Tomcat下配置数据源

Tomcat-->conf-->context.xml

 <Resource name="jdbc/oracleds" auth="Container" type="java.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="scott" password="tiger" driverClassName="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@192.168.1.101:1521:oral">
  </Resource>

 

java核心代码:

Context context = new InitialContext();DataSource ds = (DataSource) context.lookup("java:/comp/env/jdbc/oracleds");conn = ds.getConnection();
