spring装配bean

  1：如果static方法
  public static UserService creatUserServiceimpl() {
        return new UserServiceimpl();
    }
<bean id="userservice" class="com.bj.jiekou.UserServiceFactory" factory-method="creatUserServiceimpl"></bean>

2：非静态方法创建实例
  public UserService creatUserServiceimpl() {
        return new UserServiceimpl();
    }
<bean id="factory" class="com.bj.jiekou.UserServiceFactory"></bean>
<bean id="userFactory" factory-bean="factory" factory-method="creatUserServiceimpl"></bean>
    

ApplicationContext accContext = new ClassPathXmlApplicationContext("com/bj/jiekou/beans.xml");
        UserService bean2 = (UserService)accContext.getBean("userFactory");
        bean2.saveUser();
