一.使用默認(rèn)的類構(gòu)造器

1 public class PersonServiceImpl implements PersonService {
2 public void print(){
3 System.out.println("Hello Spring!!!");
4 }
5
6 }
二.使用靜態(tài)工廠
1 <bean id="PersonServiceFactoryBean" class="com.wzy.service.PersonServiceFactoryBean" factory-method="personServiceFactory"></bean>
工廠類：
1 public class PersonServiceFactoryBean {
2 public static PersonService personServiceFactory(){
3 return new PersonServiceImpl();
4 }
5 }
三.使用實(shí)例工廠
1 <bean id="PersonFactoryBean" class="com.wzy.service.PersonServiceFactoryBean"></bean>
2 <bean id="PersonService2" factory-bean="PersonFactoryBean" factory-method="PersonServiceFactory2"></bean>
3
工廠類
1 public class PersonServiceFactoryBean{
2 public PersonService PersonServiceFactory2(){
