Spring boot 使用JHipster注册表（云配置服务器作为中央服务器）集中微服务时，Bean定义覆盖异常

在JHipster注册表中集中micro service客户端配置的过程中，我目前面临一个问题。我正在使用文件系统方法来集中注册表应用程序的配置（中央配置）文件夹

在运行时启动micro service客户端应用程序的过程中，我得到了如下所示的异常

Description:

The bean 'processorStorageGateway', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

我尝试过使用注册表应用程序的中央配置文件夹.yml文件中的属性（该文件保存客户端应用程序的中央配置）这样的方法

但是还没有运气。 我还尝试在bean注入失败的接口上定义@Service annotation，如下所示

@MessagingGateway
@Service
public interface ProcessorStorageGateway { 
..... }

我看到了两个引用类文件，它们使用这个接口自动连接 FailJobscheduler和ExternalQueuelistener试图在运行时注入此bean“processorGateway”类型的接口，重命名其autowiring属性也无助于解决此问题，如下所述

@Component
public class FailJobsScheduler {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private JobService jobService;

    @Autowired
    private ProcessorStorageGateway processorStorageGateway;
............
}

@Service
public class ExternalQueueListener {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private ProcessorStorageGateway processorStorageGateway;
.....
}

目前，由于Spring Boot-2.1以后的版本在运行时不允许默认bean重写，所以无法解决这个问题。

---

开始时提到的上述打击和审判也无济于事。有人能就这个问题提供建议吗？最好的解决方法是什么？

上述问题已经通过避免一些重复的Spring注释得到了解决，这些注释已经出现在project中，在诸如@Configuration等的进一步调查中，以及在主Spring BOOT应用程序类中，通过提及要对各个包执行的组件扫描，帮助解决了问题

@Component
public class FailJobsScheduler {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private JobService jobService;

    @Autowired
    private ProcessorStorageGateway processorStorageGateway;
............
}

@Service
public class ExternalQueueListener {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private ProcessorStorageGateway processorStorageGateway;
.....
}
