Java 在abcService类中获取错误（字段xyzRepository（扩展JPA存储库）需要一个找不到的xyzRepository bean

sipRepository.java

    import sip.sipDemo.model.mysql.SipEntity;
    import org.springframework.data.jpa.repository.JpaRepository;
    import org.springframework.stereotype.Component;
    import org.springframework.stereotype.Repository;
    
    @Component
    @Repository
    public interface SipRepository extends JpaRepository<SipEntity,Integer>{
    
    }

SipController.java

    package sip.sipDemo.Controller;
    import sip.sipDemo.Service.SipService;
    import sip.sipDemo.model.mysql.SipEntity;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.ResponseBody;
    import java.util.List;
    import java.util.Optional;
    
    @Controller
    public class SipController {
    
         @Autowired
         private SipService sipservice;
    
    
        @ResponseBody
        @GetMapping(value="/")
        public String home()
        {
            return "Hello";
        }
    
        @ResponseBody
        @GetMapping(value = "/getAllEntities")
        public List<SipEntity> getAllEntities()
        {
             List<SipEntity> newList = sipservice.getAllEntities();
    
             return newList;
        }
    }

错误消息如下所示

应用程序属性

    spring.datasource.url= jdbc:mysql://localhost:3306/sys?autoReconnect=true&zeroDateTimeBehavior=convertToNull
    spring.datasource.username=root
    spring.datasource.password=******** (actual password)
    spring.jpa.hibernate.ddl-auto=update

    spring.jpa.properties.hibernate.format_sql=true
    spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect

我用过mysql数据库

主类位于最外层，包结构良好

如果我在sipService中删除sipRepository对象的@Autowire，sipRepository的控制器端点将不工作，但其余的正常工作

请提供可能的错误来源
