除了這種通過構造器注入的方法和setter方法注入外，還有一種通過anotation的方式注入 @resource
public class PersonServiceBean implements PersonService {
@ItcastResource private PersonDao personDao;
private String name;
public void setPersonDao(PersonDao personDao) {
this.personDao = personDao;
}
public PersonServiceBean(){}
public PersonServiceBean(PersonDao personDao, String name) {
this.personDao = personDao;
this.name = name;
}
public void save(){
//System.out.println(name);
personDao.add();
}
}
