描述： com.innodata.service.TopicService中的字段topicRepository需要一个类型为＆＃39; com.innodata.dao.TopicRepository＆＃39;的bean。无法找到。行动：考虑定义一个类型为＆＃39; com..data.dao.TopicRepository＆＃39;的bean。在你的配置中。**

配置bootstrap类

package com.innodata.bootstrap;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackages = "com.innodata")
public class BootstrapAplication {
    public static void main(String... strings) {
        SpringApplication.run(BootstrapAplication.class, strings);
    }
}

控制器

package com.innodata.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.innodata.modal.Topic;
import com.innodata.service.TopicService;

@RestController
public class TopicController {
    @Autowired
    private TopicService topicService;

    @RequestMapping(value = "/topics")
    public List<Topic> getAllTopics() {
        return topicService.getAllTopic();
    }

    @RequestMapping(method = RequestMethod.POST, value = "/topics")
    public void addTopic(@RequestBody Topic topic) {
        topicService.addTopic(topic);
    }
}

服务

package com.innodata.service;

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.innodata.dao.TopicRepository;
import com.innodata.modal.Topic;

@Service
public class TopicService {

    @Autowired
    private TopicRepository topicRepository;

    public List<Topic> getAllTopic() {
        List<Topic> topics = new ArrayList<Topic>();
        topicRepository.findAll().forEach(topics::add);
        return topics;
    }

    public void addTopic(Topic topic) {
        topicRepository.save(topic);
    }
}

模态是

package com.innodata.modal;

import java.io.Serializable;

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

@Entity
public class Topic implements Serializable {
    @Id
    private Integer id;
    private String name;
    private String desription;

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Topic() {

    }

    public Topic(Integer id, String name, String desription) {
        super();
        this.id = id;
        this.name = name;
        this.desription = desription;
    }

    public String getDesription() {
        return desription;
    }

    public void setDesription(String desription) {
        this.desription = desription;
    }
}

存储库层是

package com.innodata.dao;

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;

import com.innodata.modal.Topic;
@Repository
public interface TopicRepository extends CrudRepository<Topic,Integer> {

}
