在 STS 中运行 Spring Boot 应用程序时找不到 Bean

Question

I get this when I try to run my Spring Boot application in STS:

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 1 of constructor in com.greglturnquist.learningspringboot2.learningspringboot2.ImageService required a bean of type 'com.greglturnquist.learningspringboot2.learningspringboot2.ImageRepository' that could not be found.


Action:

Consider defining a bean of type 'com.greglturnquist.learningspringboot2.learningspringboot2.ImageRepository' in your configuration.

I tried adding

compile ("com.greglturnquist.learningspringboot2.learningspringboot2.ImageRepository")

to build.gradle but that's made no difference. How do I resolve this?

This is my ImageRepository class:

package com.greglturnquist.learningspringboot2.learningspringboot2;

import org.springframework.data.repository.reactive.ReactiveCrudRepository;
import reactor.core.publisher.Mono;

public interface ImageRepository extends ReactiveCrudRepository<Image, String> {

    Mono<Image> findByName(String name);

}

Answer 1

Please add @Repository to your class and run.

@Repository
public interface ImageRepository extends ReactiveCrudRepository<Image, String> {

    Mono<Image> findByName(String name);

}

Update: And also include @EnableJpaRepositories above your configuration or SpringBootApplication class to include those in component scan.

Answer 2

You forgot to add @Repository anotation to you class.

@Repository
public interface ImageRepository extends ReactiveCrudRepository<Image, String> {

}

Kindly add it and hopefully it will solve your problem.
