通过在java main函数中执行spring的代码

public class Main {

    public static void main(String[] args) throws InterruptedException {
        GenericXmlApplicationContext context = new GenericXmlApplicationContext();
        context.setValidating(false);
        context.load("classpath*:applicationContext*.xml");
        context.refresh();
        UserService userService = context.getBean(UserService.class);
        while (true) {
            System.out.println(userService.findUser());
            Thread.sleep(10000);
        }
    }
}

import org.springframework.stereotype.Service;
@Service
public class UserService {
    public String findUser() {
        return "javaniu";
    }
}
