通过Jpa操作mongodb报expected at least 1 bean which qualifies as autowire错误

报错信息

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'WebGatherService': 
Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: 
Could not autowire field: private cn.xo68.boot.webgather.repository.WebGatherRepository ; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type [cn.xo68.boot.webgather.repository.WebGatherRepository] found for dependency: 
expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: 
{@org.springframework.beans.factory.annotation.Autowired(required=true)}

解决方案

在配置类上添加mongodb的仓储类包注解

@Configuration
@EnableMongoRepositories(basePackages = {"cn.xo68.boot.webgather.repository"})
@EntityScan({"cn.xo68.boot.webgather.document"})
public class WebConfig {
}
