tomcat6配置数据库连接池

1.将数据库的jar包放到工程的lib下(jar包见附件)

2.在tomcat的/conf/context.xml文件中添加(一些参数需要修改)

<Resource name="jdbc/oracle" type="javax.sql.DataSource"

driverClassName="oracle.jdbc.OracleDriver" url="jdbc:oracle:thin:@127.0.0.1:1521:orcl"

username="dtm" password="dtm" maxActive="50" maxIdle="20" maxWait="10000" />

 3.测试代码

public class DBConn {

private static Connection conn;

public static Connection getConn(String name){

try {

Context initContext = new InitialContext();

DataSource ds = (DataSource) initContext.lookup("java:comp/env/jdbc/oracle");

conn = ds.getConnection();

} catch (NamingException e) {

e.printStackTrace();

} catch (SQLException e) {

e.printStackTrace();

}

return conn;

}

}

PS：红色字体部分要相同
