在更改变量的可见性时，使用spring时出错。
我有这个代码（它工作得很好）

@Component
public class TennisCoach implements Coach {
    @Autowired
    public FortuneService fortuneService;
    @Override
    public String getDailyWorkout() {
        return "Do tennis stuff!";
    }
    @Override
    public String getFortune() {
        return fortuneService.getFortune();
    }
}

( FortunateService 是一个接口，我有一个类 HappyFortunateService 它实现了它，我用 @Component 以及）
用这个主要方法

public static void main(String[] args) {
    ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
    Coach annotatedCoach = context.getBean("tennisCoach", Coach.class);
    System.out.println(annotatedCoach.getDailyWorkout());
    System.out.println(annotatedCoach.getFortune());
    context.close();
}

当我打开 TennisCoach 班级 fortunateService 可变可见性 private ，我得到这个错误：

有人知道为什么吗？spring版本：5.2.9 java se15
编辑：我的项目是将springjar文件添加到modulepath的，我没有使用maven。
我的module-info.java如下所示：

module spring_project {
    requires spring.context;
    requires java.logging;
    requires spring.beans;
    exports me.davichete.springproject;
}

编辑：我在删除module-info.java时测试了它，现在它似乎工作了，可能与@menelaos的答案有关
