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();
			}
		}

2、建接口 PersonService

		public  interface  PersonService{
			public  void  savePerson();
		}

3、建类 PersonServiceImpl  实现 PersonService

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

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

4、建接口 PersonDao

		public interface PersonDao{
			public  void  savePerson();
		}

5、类 PersonDaoImpl  实现 PersonDao

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

6、配置文件 applicationContext-mvc.xml

7、建测试类 MVCTest

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

        结果：输出 save person dao
