**1.工廠方法** ~~~ package com.nobb.factory; import com.nobb.bean.User; public class UserFactory { public static User getUser1(){ User u =new User(); u.setId(1); u.setName("nobb"); return u; } } ~~~ **2.spring配置** ~~~ <bean name="user2" class="com.nobb.factory.UserFactory" factory-method="getUser1"></bean> ~~~ **3.測試代碼** ~~~ public class App { public static void main(String[] args){ //類路徑Xml應用上下文容器 ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml"); // User user = (User)ac.getBean("user"); // System.out.println(user); User user2 = (User)ac.getBean("user2"); System.out.println(user2); } } ~~~ **4.測試結果（結論：applicationContext會將實例化所有定義的bean）** 調用了無參構造 調用了無參構造 User{id=1, name='nobb'}
