在做SearchTest的时候启动Springboot遇到了这个错误

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘searchController’ defined in file [/Users/LyneDefense/Programming/sparkCode/ad-system-spring-cloud/ad-service/ad-search/target/classes/com/pinjhu/ad/controller/SearchController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘search.ISearch’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

我自己分析的是
在SearchController这个类里面：

private final ISearch search ;

private final RestTemplate restTemplate;

private final SponsorClient sponsorClient;



@Autowired
public SearchController(ISearch search, RestTemplate restTemplate, SponsorClient sponsorClient) {
    this.search = search;
    this.restTemplate = restTemplate;
    this.sponsorClient = sponsorClient;
}

这个Autowired 注入有问题，但是我不知道怎么改。能帮忙看一下吗。
