java - Spring 服务名称与接口(interface)名称冲突

Question

我有一个接口(interface)名称

public interface ScoreDao {

   public int storeScore(OverallScore overallScore);

   public void storeIndividualScore(ScoreTO scoreTO);
}

实现类如下

@Repository("scoreDao")
public class ScoreDaoImpl implements ScoreDao {
   @Override
   public int storeScore(OverallScore overallScore) {
      //Implementation 
   }
   @Override
   public void storeIndividualScore(ScoreTO scoreTO){
       //Implementation
   }
}

来电者正在使用如下服务

@Service("scoreService")
public class scoreServiceImpl implements IScoreService {
   @Autowired
   private ScoreDao scoreDao;

   @Override
   public int storeScore(OverallScore overallScore) {
      return scoreDao.storeOverallScore(overallScore);
   }

   @Override
   public void storeIndividualScore(ScoreTO scoreTO) {
      scoreDao.storeIndividualScore(scoreTO);
   }
}

我正在使用 spring 4.x，在部署时出现如下 bean 冲突错误。

Caused by: java.lang.RuntimeException: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'ScoreDao' for bean class [ScoreDao] conflicts with existing, non-compatible bean definition of same name and class [ScoreDaoImpl]

当我将接口(interface)名称更改为 IScoreDao 时，它可以正常工作。是因为服务名@Repository("scoreDao") 和接口(interface)名一样吗？

Answer 1

简单的答案是是，这是因为您有一个名为ScoreDao 的接口(interface)，并且您将其实现为@Repository("scoreDao ")

两种解决方法:

1. 将 ScoreDao 重命名为其他名称

2. 将 @Repository("scoreDao") 更改为 @Repository 以便它将使用默认名称
