java - 引起：org.springframework.beans.factory.NoSuchBeanDefinitionException：没有“repository.RoleRepository”类型的合格bean可用

Question

我是spring boot的新手，当我想启动应用程序时遇到问题，我有这个错误：

Exception in thread "restartedMain" java.lang.reflect.InvocationTargetException
    at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'repository.RoleRepository' available

    at mereuta.marian.tennis01.Tennis01Application.main(Tennis01Application.java:23)
    ... 5 more

这是我的应用程序代码：

package mereuta.marian.tennis01;

import model.Horaire;
import model.Role;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import repository.HoraireRepository;
import repository.RoleRepository;

import java.sql.Time;

@SpringBootApplication
public class Tennis01Application {

    public static void main(String[] args) {
    ApplicationContext context= SpringApplication.run(Tennis01Application.class, args);

    //  HoraireRepository horaireRepository=context.getBean(HoraireRepository.class);

        //horaireRepository.save(new Horaire(new Time(8, 0,0), new Time(22,0,0),"Lundi"));

        RoleRepository roleRepository=context.getBean(RoleRepository.class);

        roleRepository.save(new Role("client"));
    }
}
