服務豆沒有得到自動裝配在春季啓動

我創建一個控制器，服務和信息庫class.All一個春天啓動應用程序，這些定義如下：服務豆沒有得到自動裝配在春季啓動

MainClass

@SpringBootApplication 
public class MainClass extends SpringBootServletInitializer { 

    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(MainClass.class); 
    } 

    public static void main(String[] args) { 
     SpringApplication.run(MainClass.class, args); 
    } 

}

控制器：

@RestController 
@EnableAutoConfiguration 
public class ExampleController { 

    public static final Logger logger = LoggerFactory.getLogger(ExampleController.class); 

    private CustomReportService customReportService; 

    @Autowired 
    public void setCustomReportService(CustomReportService customReportService){ 
     this.customReportService = customReportService; 
    } 

    @RequestMapping(value="/api/report/list", method= RequestMethod.GET) 
    public ResponseEntity<Collection<CustomReport>> listAllCustomReports(){ 
     return new ResponseEntity<>((Collection<CustomReport>) customReportService.listAllCustomReports(), HttpStatus.OK); 
    } 
}

服務接口：

public interface CustomReportService { 
    Iterable<CustomReport> listAllCustomReports(); 
}

服務默認地將Impl：

@Service 
public class CustomReportServiceImpl implements CustomReportService{ 

    @Autowired 
    private CustomReportRepository customReportRepository; 

    @Autowired 
    public void setCustomReportRepository(CustomReportRepository customReportRepository){ 
     this.customReportRepository = customReportRepository; 
    } 

    @Override 
    public Iterable<CustomReport> listAllCustomReports() { 
     return customReportRepository.findAll(); 
    } 

}

庫：

public interface CustomReportRepository extends CrudRepository<CustomReport, Long> { 
}

有關部署，我的應用程序無法啓動與FOLL錯誤：

請告訴我，我要去哪裏錯了。

謝謝！

您的類'CustomReportServiceImpl'不是由Spring管理的，或者Spring不可發現的。在你的配置類中檢查'@ ComponentScan'註解並相應地進行編輯，以便Spring容器可以找到它。 –

讓我知道它是否修復它 –

'@ EnableAutoConfiguration'僅適用於'@ Configuration'類。所以在你的情況下，它不會做任何事情，也可以通過使用'@ SpringBootApplication'來暗示。我懷疑你的'MainClass'f不在'com.test'中，而是在它的一些子包中。建議將bootstrapping類放在最高的包中，在你的例子'com.test'或任何實際的包中。由於'@ ComponentScan'被'@ SpringBootApplication'隱含，但是它從包開始，而MainClass不在其他包（因此是根包）中定義。 –

從控制器中刪除@EnableAutoConfiguration，它已經在@SpringBootApplication。您的MainClass應該位於根包中。也嘗試添加@ComponentScan("your.root.package")您MainClass

確保你把你的主要春季啓動應用程序的入口類MainClass在你的工作包的頂部，與所有其他類下。
無需將@EnableAutoConfiguration添加到您的控制器中，因爲@SpringBootApplication已包含該功能。
在CustomReportServiceImpl您正在混合字段&構造函數汽車接線爲customReportRepository，只選擇一個。
