为什么春季靴找不到我的豆子? [英] Why is spring boot not finding my beans?

问题描述

我有以下错误:

Parameter 0 of constructor in com.yyy.zzz.xxx.service.ControlService required a bean of type 'com.yyy.zzz.xxx.service.composeXML.ComposeCounterService' that could not be found.

通常这是因为我忘记注释服务或 界面，但是我整个上午都在上课，找不到 任何缺少的注释..

Usually this is because i forget to annotate either the Service or the interface, but i've been looking classes the whole morning and cant find any missing annotations..

此时的界面只是:

@Component
public interface ComposeCounterService {
CLASSX init(List<YYY> owners) throws JAXBException;
}

和隐含服务如下，并且在这种情况下，包含init()方法.

and implimenting service is as follows, and contains init() method if that matters in this case.

@Service
public class ComposeCounterImpl implements ComposeCounterService {
/*** loots of code
}

和ApplicationConfig文件位于服务包上方一层.在这篇文章中标记为xxx.

and ApplicationConfig file is located one level above the service package. marked xxx in this post.

它包含以下软件包扫描:

It contains the following package scan:

@SpringBootApplication
scanBasePackages = {"com.yyy.zzz.xxx")

我还尝试了一系列扫描，例如:

i also tried it with array of scans like:

scanBasePackages = {"com.yyy.zzz.xxx", "com.yyy.zzz.xxx.service.composeXML"})

并且在.service之后没有composeXML 这些都不起作用.

and without the composeXML after .service None of these works.

我很确定我在这里遗漏了一些东西，请发送帮助.

im pretty sure im missing something here, please send help.

注射方式:

private final ComposeCounterService composeCounterService;

public ControlService(ComposeCounterService composeCounterService) {
    this.composeCounterService = composeCounterService;
}

推荐答案

错误的导入是:

import org.jvnet.hk2.annotations.Service;

正确的是:

import org.springframework.stereotype.Service;

如果仅让您的IDE建议导入，然后按Enter键而不阅读添加的内容，那么结果就是这样.

If you just let your IDE suggest the import and press enter without reading which one it adds, this is the result.
