Spring Boot @Controller拒绝使用@Autowired
我使用this tutorial来构建Spring Boot应用程序。乍一看似乎非常容易，但我马上遇到了许多问题。尝试访问/hi或/thing时，tomcat 7会返回404 error。如何解决？
@Controller
public class MainController {
@Autowired
ParserService parserService;
@RequestMapping("/thing")
public Record thing() {
return new Record();
}
@RequestMapping(value="/hi", method= RequestMethod.GET)
public @ResponseBody String displayStartPage(){
return "{hello}";
}
}
应用
@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = "go")
@EntityScan
public class Application extends SpringBootServletInitializer{
public static void main(final String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
RecordDao
@Transactional
@Service("recordDao")
public interface RecordDao extends CrudRepository<Record, Long> {
}
PS。在这里，我不得不添加@Service("recordDao")，因为IntelliJ警告Cannot Autowire bean.虽然在教程中没有显示此行。

UPDATE5
当我将其作为maven spring-boot目标运行时，它会出错：
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mainController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: go.service.ParserService go.controller.MainController.parserService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'parserService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: go.dao.RecordDao go.service.ParserService.recordDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [go.dao.RecordDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

答案 0 :(得分：1)
将您的Application课程放入课程包中（例如＆＃34; go＆＃34;）。否则，Spring Data存储库扫描无法工作（它必须扫描类路径上的所有jar文件）。
