spring加载配置文件时会调用
public void setCustomerService(CustomerService customerService) {
this.customerService = customerService;
}
set方法将customerService 注入

换成注解注解方式@Autowired就可以移除<property name="customerService" ref="customerService"></property>
变为

二: 注解 <context:annotation-config/>与<context:component-scan/>
