Spring 利用springIOC和DI实现MVC的模拟例子

1、建类 PersonAction.java

public  class  PersonAction{
			private  PersonService  personService;
			封装……

			public  void  savePerson(){
				this.personService.savePerson();
			}
		}

public  interface  PersonService{
			public  void  savePerson();
		}

public  class PersonServiceImpl  implements  PersonService {
			private  PersonDao  personDao;
			封装personDao……

			@Override
			public  void  savePerson(){
				this.personDao.savePerson();
			}
		}

public interface PersonDao{
			public  void  savePerson();
		}

public  class  PersonDaoImpl  implements  PersonDao{
			@Override
			public  void  savePerson(){
				s.o.p("save  person  dao");
			}
		}

<bean  id="personDao"  class="cn.google.spring.PersonDaoImpl"></bean>

		<bean  id="personService"  class="cn.google.spring.PersonServiceImpl">
			<property  name="personDao">
				<ref  bean="personDao">
			</property>
		</bean>

		<bean  id="personAction"  class="cn.google.spring.PersonAction">
			<property  name="personService">
				<ref  bean="personService">
			</property>		
		</bean>

public  class  MVCTest  extends  SpringInit{
			@Test
			public  void  test(){
				PersonAction  personAction  = (PersonAction)context.getBean("personAction");
				personAction.savePerson();
			}
		}
