struts2-不带struts2 spring插件的spring集成

我想知道SpringBeanPersonService对象是如何在不使用struts-spring插件的情况下分配给setPersonService方法的，当我尝试跟踪操作类methodsetPersonService时，我得到了JdkDynamicAopProxy关键字。但我对JdkDynamicAopProxy一无所知

撑杆动作

 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;
        }
    }

你的问题是什么是JDK动态AOP代理？我的问题是struts2 action对象在没有spring插件的情况下是如何获得spring服务的。这是spring处理此问题的一种方式，以下是spring源代码中的详细信息，而不必查看spring配置，就不可能知道哪些类。如果没有Spring插件，S2本身将完全从运行时的Spring处理中删除，您需要提供更多关于S2和Spring配置的信息，以及您正在部署的库。
