Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

• 原因：@Autowired注解注入时发现有多个实现类，而项目中并无多个实现类的情况，最终发现是由于Hateoas的新功能产生的

• 解决方案：在swagger配置文件中添加以下代码

  @Primary
  @Bean
  public LinkDiscoverers discoverers() {
      List<LinkDiscoverer> plugins = new ArrayList<>();
      plugins.add(new CollectionJsonLinkDiscoverer());
      return new LinkDiscoverers(SimplePluginRegistry.create(plugins));
  }
