Spring @ComponentScan 未被拾取，可能是由于@SpringBootApplication 中的@EnableAutoConfiguration？
Spring @ComponentScan isn't picked up, maybe due to @EnableAutoConfiguration in @SpringBootApplication?
我是 SpringBoot 的新手，目前正在了解 spring 具有休眠功能的应用程序的基本功能。
我有一个包 com.yyyyyyyyyyy.coaching，如果我将所有 @Entity 定义放在那里，应用 运行 就会成功。我很高兴起床 运行 很快。
现在我将一个实体移动到 com.yyyyyyyyyyy.i18n.bo 因为它稍后应该在其他地方使用并且休眠会抛出以下错误：
Caused by: org.hibernate.AnnotationException: @OneToOne or @ManyToOne on com.yyyyyyyyyyy.coaching.bo.Topic.descriptionStrings references an unknown entity: com.yyyyyyyyyyy.i18n.bo.Localized
（完整的 --debug 应用程序启动见下文）
我知道应该使用@ComponentScan 来指定扫描哪些包以获取注释。
我仔细检查过 javax.persistence.Entity 到处都在使用，而不是 hibernate 包中的那个。
这是我的程序入口点：
@SpringBootApplication(scanBasePackages={"com.yyyyyyyyyyy"})
//@Configuration
//@ComponentScan(basePackages={"com.yyyyyyyyyyy.coaching", "com.yyyyyyyyyyy.i18n"})
@Import(AppConfig.class)
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
它没有找到带有 scanBasePackages 的实体，在主要 class 上使用 ComponentScan，并且在使用 @Import 和另一个配置时 class "AppConfig"。我还尝试使用 ApplicationBuilder 而不是 SpringApplication 像这样 new SpringApplicationBuilder().sources(AppConfig.class).main(DemoApplication.class).运行(args);但无济于事。
我可以从调试输出中看到以下行：
2015-11-18 08:08:48.407 DEBUG 13780 --- [ main] o.s.b.a.AutoConfigurationPackages : @EnableAutoConfiguration was declared on a class in the package 'com.yyyyyyyyyyy.coaching'. Automatic @Repository and @Entity scanning is enabled.
我想这不会有什么坏处，因为它来自 @SpringBootApplication 注释
似乎也没有包含 AppConfig class，因为我添加了未打印的调试输出。
@Configuration
//@Profile("production")
@ComponentScan(basePackages={"com.yyyyyyyyyyy.coaching", "com.yyyyyyyyyyy.i18n"})
public class AppConfig {
public AppConfig() {
System.out.println("------------------------------Init AppConfig-------------------------");
}
@PostConstruct
public void doSomething() {
System.out.println("------------------------------Done AppConfig-------------------------");
}
}
关于这个的 help/ideas 吗？
谢谢。

将 DemoApplication class 移动到 com.yyyyyyyyyyy 包，一切都应该有效。 com.yyyyyyyyyyy 中的所有内容都应自动选取。
检查 this 了解 spring 引导如何构建推荐
更新：
也如您在参考文档中看到的那样添加
将 @EntityScan(basePackages={"com.yyyyyyyyyyy.coaching", "com.yyyyyyyyyyy.i18n"}) 添加到 DemoApplication 即可。
