本文介绍了@SpringBootApplication-ComponentScan无法在新的Eclipse项目中正常工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我最近开始使用Eclipse(从IntelliJ Idea移出)，但是无论我开始写什么新的SpringBoot应用程序，我总是会遇到这个问题.我的主类上的@SpringBootApplication无法按预期工作.我应该能够在不添加@ComponentScann批注的情况下走开(我知道它将使之工作)，但是本文的目的是找出原始故障的路由原因.我已经知道解决方法.我的应用始终会显示以下错误消息:

程序包com.ge.workplacelogger.repositories;导入java.util.List;导入org.springframework.data.repository.CrudRepository;导入org.springframework.stereotype.Repository;导入com.ge.workplacelogger.models.Event;导入com.ge.workplacelogger.models.Worker;@资料库公共接口EventRepository扩展了CrudRepository< Event，Integer>.{void saveEvent(Event event);void deleteEvent(Event event);List< Event>findAllEvents();事件findEventByEventId(Integer eventId);List< Event>findEventsByWorker(工人工人);} 最后，是我要@Autowire EventRepository的服务:
程序包com.ge.workplacelogger.services;导入java.util.List;导入org.springframework.beans.factory.annotation.Autowired;导入org.springframework.stereotype.Service;导入com.ge.workplacelogger.models.Event;导入com.ge.workplacelogger.models.Worker;导入com.ge.workplacelogger.repositories.EventRepository;@服务公共类EventServiceDbImpl实现EventService {@AutowiredEventRepository eventRepository;@Override公共无效saveEvent(事件事件){eventRepository.saveEvent(event);}@Override公共无效deleteEvent(事件事件){eventRepository.deleteEvent(event);}@Override公共列表<事件>findAllEvents(){返回eventRepository.findAllEvents();}@Override公共事件findEventByEventId(Integer eventId){返回eventRepository.findEventByEventId(eventId);}@Override公共列表<事件>findEventsByWorker(工人工人){返回eventRepository.findEventsByWorker(worker);}} 据我了解，主类(位于com.ge.workplacelogger包中)的@SpringBootApplication将在所有子包上用作@ComponentScan.我所有的服务，存储库，模型都在com.ge.workplacelogger包的子包中，所以我真的不知道出什么问题了.这可能是一个荒谬的问题，但是与Eclipse有什么关系吗?以前从来没有IntelliJ有任何问题.

我发现应用程序属性中的一个错误导致了该问题:

spring.datasource.url = jdbc:postgresql://localhost:5432/workplacelogger 也删除了应用程序属性中的以下行，因为先前的解析器"建议:
spring.autoconfigure.exclude = org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration 该代码现在可以运行，并且进行了一些其他小的更正，这些不是本票证的内容.这是程序员应该不时退后一步以找到导致错误的路由原因的证据:)我迷失了细节，并且花了很多时间在我的家庭项目中找到这样的错别字"./p>
谢谢大家的光临！
I recently started using Eclipse (moved from IntelliJ Idea) but whatever new SpringBoot app I start writing, I always get this problem. The @SpringBootApplication on my main class does not work as intended. I should be able to get away without adding the @ComponentScann annotation (I know it would make it work), but the intention of this post is to find out the route cause of the original failure. I already know work-arounds. My app always breaks with the following error message:

Description:
Field eventRepository in com.ge.workplacelogger.services.EventServiceDbImpl required a bean of type 'com.ge.workplacelogger.repositories.EventRepository' that could not be found.
Action:
Consider defining a bean of type 'com.ge.workplacelogger.repositories.EventRepository' in your configuration.
So, here is the code that I am using
Main class:
package com.ge.workplacelogger;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WorkplaceloggerApplication {
public static void main(String[] args) {
SpringApplication.run(WorkplaceloggerApplication.class, args);
}
}
Repository interface:
package com.ge.workplacelogger.repositories;
import java.util.List;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import com.ge.workplacelogger.models.Event;
import com.ge.workplacelogger.models.Worker;
@Repository
public interface EventRepository extends CrudRepository<Event, Integer> {
void saveEvent(Event event);
void deleteEvent(Event event);
List<Event> findAllEvents();
Event findEventByEventId(Integer eventId);
List<Event> findEventsByWorker(Worker worker);
}
and finally, the Service where I would like to @Autowire the EventRepository:
package com.ge.workplacelogger.services;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.ge.workplacelogger.models.Event;
import com.ge.workplacelogger.models.Worker;
import com.ge.workplacelogger.repositories.EventRepository;
@Service
public class EventServiceDbImpl implements EventService {
@Autowired
EventRepository eventRepository;
@Override
public void saveEvent(Event event) {
eventRepository.saveEvent(event);
}
@Override
public void deleteEvent(Event event) {
eventRepository.deleteEvent(event);
}
@Override
public List<Event> findAllEvents() {
return eventRepository.findAllEvents();
}
@Override
public Event findEventByEventId(Integer eventId) {
return eventRepository.findEventByEventId(eventId);
}
@Override
public List<Event> findEventsByWorker(Worker worker) {
return eventRepository.findEventsByWorker(worker);
}
}
As far as I understand, the @SpringBootApplication on my main class (in package com.ge.workplacelogger) will work as @ComponentScan on all subpackages. All my services, repositories, models are in a subpackage of the package com.ge.workplacelogger, so I really have no ide what goes wrong. It might be a ridiculous question, but does it have anything to do with Eclipse? Never had any problem with IntelliJ before.
Thank you very much for the answer in advance!
EDIT:Here is my entity as well for evaluation.

@Entity

public class Event {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer eventId;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "workerId")
private Worker worker;
private boolean logIn;
private LocalDateTime timestamp;
private String comment;
public Event() {
}
public Event(Integer eventId, Worker worker, boolean logIn, LocalDateTime timestamp, String comment) {
this.eventId = eventId;
this.worker = worker;
this.logIn = logIn;
this.timestamp = timestamp;
this.comment = comment;
}
public Integer getEventId() {
return eventId;
}
public void setEventId(Integer eventId) {
this.eventId = eventId;
}
public Worker getWorker() {
return worker;
}
public void setWorker(Worker worker) {
this.worker = worker;
}
public boolean isLogIn() {
return logIn;
}
public void setLogIn(boolean logIn) {
this.logIn = logIn;
}
public LocalDateTime getTimestamp() {
return timestamp;
}
public void setTimestamp(LocalDateTime timestamp) {
this.timestamp = timestamp;
}
public String getComment() {
return comment;
}
public void setComment(String comment) {
this.comment = comment;
}
@Override
public String toString() {
return "Event [eventId=" + eventId + ", worker=" + worker + ", logIn=" + logIn + ", timestamp=" + timestamp

解决方案
I have found a mistake in the application properties that caused the issue:
original line:
spring.datasource.url=jdbc:postgres://localhost:5432/workplacelogger
correct line:
spring.datasource.url=jdbc:postgresql://localhost:5432/workplacelogger
Also deleted the following line in application properties as the previous "resolver" has suggested:
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
The code runs now with some additional minor corrections that are not the subject of this ticket.Here is the evidence that a programmer should step back from time to time to find the route cause of the error :) I was lost in the details and it took a lot of time to find such a "typo" in my home project.
Thank you all for your time!
