struts-spring プラグインを使用せずに、Spring Bean( PersonService ) オブジェクトがsetPersonServiceメソッドにどのように割り当てられているか知りたいのですが、アクション クラス メソッド ( setPersonService ) をトレースしようとすると、 JdkDynamicAopProxyキーワードが表示されます。しかし、私はJdkDynamicAopProxyについて何も知りません
ストラットアクション
public class AllPersonsFinder extends ActionSupport {
private List<Person> persons;
private transient PersonService personService;
@Override
public String execute() throws Exception {
persons = personService.findAllEmployees();
return SUCCESS;
}
public List<Person> getPersons() {
return persons;
}
public void setPersons(List<Person> persons) {
this.persons = persons;
}
public PersonService getPersonService() {
return personService;
}
public void setPersonService(PersonService personService) {
this.personService = personService;
}
}
