我尝试遵循以下快速入门指南:

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

我昨天有这个工作,我觉得我没有改变任何东西(即使我必须改变),但是今天我遇到了一个异常(exception)。我需要更多的眼睛。

我的仓库:

public interface PlayerRepository extends MongoRepository<Player, String> {

public List<Player> findByEmail(String email);

}

我的实体:

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;
}

}

我正在使用 STS,当我作为“Spring Boot App”运行时。我得到以下异常:

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!

SpringBoot应用:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import ie.evince.repository.PlayerRepository;

@SpringBootApplication
public class SpringBootMongodbApplication implements CommandLineRunner {

@Autowired
private PlayerRepository playerRepository;

public static void main(String[] args) {
SpringApplication.run(SpringBootMongodbApplication.class, args);
}

@Override
public void run(String... args) throws Exception {
System.out.print(playerRepository.count());
}

}

最佳答案

看起来您同时拥有 Neo4j 数据库和 Mongo 数据库存储库,出于某种原因,spring boot 正在尝试为 Neo4j 数据库加载人员存储库。如果您希望 spring boot 加载为 Mongo 数据库存储库,请尝试从类路径中删除 Neo4j。

关于java - 是什么原因造成的 (MongoDB) : PropertyReferenceException: No property findAll found for type,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/41097940/
