Spring Boot测试，autowire找不到Bean

[auroradad]

怎么整都抱错，死活找不到bean，哪个兄弟知道哪有问题？

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.DemoApplication$ReservationRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

package com.example;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.JpaRepository;

@SpringBootApplication
public class DemoApplication {

	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
	}

	interface ReservationRepository extends JpaRepository<Booking, Long> {
	}

	@Entity
	class Booking {

		Booking() {
		}

		public Booking(String bookingName, int groupSize) {

		}

		@Id
		@GeneratedValue
		private long id;

		private String bookingName;
		private int groupSize;

		public long getId() {
			return id;
		}

		public void setId(long id) {
			this.id = id;
		}

		public String getBookingName() {
			return bookingName;
		}

		public void setBookingName(String bookingName) {
			this.bookingName = bookingName;
		}

		public int getGroupSize() {
			return groupSize;
		}

		public void setGroupSize(int groupSize) {
			this.groupSize = groupSize;
		}
	}

}

package com.example;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import com.example.DemoApplication.ReservationRepository;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {

	@Autowired 
	ReservationRepository reservationRepository;
	
	@Test
	public void contextLoads() {
	}

}

引用 2 楼 m2200 的回复:

interface ReservationRepository extends JpaRepository<Booking, Long> { } 放外面，顺便检查下你配置如何扫描包的。

Spring Boot没有配置文件的 问题原因：ReservationRepository 是接口，没有实现，另外写的实现类需要注解标注

[游一游走一走]

请尝试将ReservationRepository，Booking使用单独的文件，并且指定为public

interface ReservationRepository extends JpaRepository<Booking, Long> { } 放外面，顺便检查下你配置如何扫描包的。

[爱睡觉的阿狸]

interface ReservationRepository extends JpaRepository<Booking, Long> { } 这个最好单独用一个类文件，很可能你放类里面，spring没有扫描到。

写到类里面了，所以找不到。。。。。。可以在同一个文件里面，但不能是内部类。。。。
