数据库连接池Driud使用JbbcUtils工具包

public class JdbcUtils {
    private static DataSource dataSource=null;
    static{
        try {
            Properties p = new Properties();
            p.load(ClassLoader.getSystemResourceAsStream("druid.properties"));

//          p.load(new FileInputStream("jdbc-demo/src/druid.properties"));
//获取连接池对象
            dataSource = DruidDataSourceFactory.createDataSource(p);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
//    返回连接池对象方法
    public static DataSource getDateSource(){
        return dataSource;
    }
//    返回连接对象方法
    public static Connection getConnection(){
        Connection conn = null;
        try {
            conn = dataSource.getConnection();
        } catch (SQLException throwables) {
            throwables.printStackTrace();
        }
        return conn;
    }
}
