我尝试遵循以下快速入门指南：

我昨天做了这件事，我觉得我什么都没有改变（尽管我必须改变），但是今天我得到了一个例外。我需要更多的眼睛

我的存储库：

public interface PlayerRepository extends MongoRepository<Player, String> {

    public List<Player> findByEmail(String email);

}
我正在使用STS，当我以“Spring Boot应用程序”运行时。我得到以下例外情况：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'springBootMongodbApplication': Unsatisfied dependency expressed through field 'playerRestRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'playerRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property findAll found for type Player!

看起来您同时拥有Neo4j db和Mongo db存储库，出于某种原因，spring boot正在尝试为Neo4j db加载person存储库。如果希望spring引导加载为Mongo db respository，请尝试从类路径中删除Neo4j。

如何定义spring bean？通过注释或xml？嗨@XtremeBaumer，它是基于注释的。如图所示：（spring boot应用程序）可能您已将
PlayerRepository
移动到与主类不同的包中？是否显示了所有代码？错误似乎不是来自您列出的代码。我将添加我的SpringBoot应用程序-它是bog标准。
