首先當然要下載驅動，我用的是mysql-connector-java-5.0.4-bin.jar

public?class?ConnectionFactory?{????
????public?static?Connection?getConnection(){
????????Connection?conn?=null;????????
????????try?{
????????????Class.forName("com.mysql.jdbc.Driver");
????????????conn?=DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/st_storm?useUnicode=true&characterEncoding=utf-8","root",?"");
????????}?catch?(ClassNotFoundException?e)?{
????????????System.out.println("?No?class?"?+?"?found?error");?e.printStackTrace();
????????}?catch?(SQLException?e)?{
????????????System.out.println("Failed?to?get?connection?:"?+e.getMessage());?e.printStackTrace();
????????}
????????System.out.println("conn=="+conn);
????????return?conn;
????}

st_storm是我要連接的庫名
