导致此问题的原因（MongoDB）：PropertyReferenceException：找不到类型的属性findAll

标签： java mongodb spring-boot

我尝试按照以下快速入门提示：

https://spring.io/guides/gs/accessing-data-mongodb/

昨天我有这个工作，我觉得我没有改变任何东西（即使我必须有），但今天我得到一个例外。我需要更多的眼睛。

我的存储库：

 var powerShell = PowerShell.Create().AddScript(someScript);

我的实体：

public interface PlayerRepository extends MongoRepository<Player, String> {

    public List<Player> findByEmail(String email);

}

我正在使用STS，当我运行'Spring Boot App'时。我得到以下异常：

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.index.Indexed;

public class Player {

    @Id
    private String id;
    private String name;
    @Indexed(unique=true)
    private String email;

    public Player() {

    }

    public Player(String id, String name, String email) {
        this.id = id;
        this.name = name;
        this.email = email;
    }

    @Override
    public String toString() {
        return "Player [id=" + id + ", name=" + name + ", email=" + email + "]";
    }

    public String getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getEmail() {
        return email;
    }

}

SpringBootApplication：

看起来你有Neo4j数据库和Mongo数据库存储库，并且出于某种原因，spring boot正在尝试加载Neo4j数据库的人员存储库。如果要将Spring引导加载为Mongo db存储库，请尝试从类路径中删除Neo4j。
