Java 为什么我的Spring@Autowired field num位于非控制器&x27；什么课？

我有这样的服务课：

@Service
public class ReminderServiceImpl implements ReminderService {

@Autowired
private RemindRepository repository;

public Remind save(Remind remind) {
    return repository.saveAndFlush(remind);
}

public List<Remind> getAll() {
    return repository.findAll();
}

}

My mvc-dispatcher-servlet.xml：

 <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"

我做错了什么

XMLConverter类在哪个包中？如果它不在基本包“服务器”的下方，@Autowired注释将不起作用，因为将不会扫描注释。

此类位于“服务器”包内。

@组件是否正确地从Spring包导入？可能不是。。。我刚刚添加了一个注释。如何导入？请检查导入语句以确保导入的是正确的。我以前输入了错误的东西，花了很长时间试图了解发生了什么。嗯。。。我不明白导入是什么意思…@Component annotation刚刚导入：import org.springframework.stereotype.Component；仅此而已……就是这样，这是正确的答案
@Component
public class XMLConverter implements ResourceLoaderAware {

@Autowired
private ReminderService service;

... 


public void convertFromXMLToObject() throws XmlPullParserException, IOException {

...
Remind r=new Remind();
r.setTitle(parser.getText());
service.save(r);

...

}

}
