Java Spring数据总是返回一个带有反应式mongo存储库的空数组

我正在尝试使用反应式mongo库和spring数据构建一个应用程序。但是，每次我点击应用程序并使用

dao.findAll（）

时，我都会得到一个空的结果数组。 请在下面查找代码

/config/MongoAdminConfig.java

@EnableReactiveMongoRepositories
public class MongoAdminConfig extends AbstractReactiveMongoConfiguration {

    @Override
    @Bean
    public MongoClient reactiveMongoClient() {
        MongoClientSettings settings = MongoClientSettings.builder()
                .applyConnectionString(new ConnectionString("mongodb://localhost:27017/projects"))
                .build();
        return MongoClients.create(settings);
    }

    @Override
    protected String getDatabaseName() {
        return "projects";
    }
}

@RestController
@RequestMapping("accounts")
public class AccountController {

    @Autowired
    private AccountDao accountDao;

    @GetMapping
    public Flux<Account> getAllAccounts() {
        return this.accountDao.findAll();
    }
}

public interface AccountDao extends ReactiveCrudRepository<Account, String> {
}

@Document(collection = "accounts")
public class Account {
    @Id
    private String id;

    private String accountNumber;
    private String type;
    private String status;
    private double availableBalance;
    private String currency;

    //getters and setters 
}

/controllers/AccountController.java

@EnableReactiveMongoRepositories
public class MongoAdminConfig extends AbstractReactiveMongoConfiguration {

    @Override
    @Bean
    public MongoClient reactiveMongoClient() {
        MongoClientSettings settings = MongoClientSettings.builder()
                .applyConnectionString(new ConnectionString("mongodb://localhost:27017/projects"))
                .build();
        return MongoClients.create(settings);
    }

    @Override
    protected String getDatabaseName() {
        return "projects";
    }
}

@RestController
@RequestMapping("accounts")
public class AccountController {

    @Autowired
    private AccountDao accountDao;

    @GetMapping
    public Flux<Account> getAllAccounts() {
        return this.accountDao.findAll();
    }
}

public interface AccountDao extends ReactiveCrudRepository<Account, String> {
}

@Document(collection = "accounts")
public class Account {
    @Id
    private String id;

    private String accountNumber;
    private String type;
    private String status;
    private double availableBalance;
    private String currency;

    //getters and setters 
}

/models/Account.java

@EnableReactiveMongoRepositories
public class MongoAdminConfig extends AbstractReactiveMongoConfiguration {

    @Override
    @Bean
    public MongoClient reactiveMongoClient() {
        MongoClientSettings settings = MongoClientSettings.builder()
                .applyConnectionString(new ConnectionString("mongodb://localhost:27017/projects"))
                .build();
        return MongoClients.create(settings);
    }

    @Override
    protected String getDatabaseName() {
        return "projects";
    }
}

@RestController
@RequestMapping("accounts")
public class AccountController {

    @Autowired
    private AccountDao accountDao;

    @GetMapping
    public Flux<Account> getAllAccounts() {
        return this.accountDao.findAll();
    }
}

public interface AccountDao extends ReactiveCrudRepository<Account, String> {
}

@Document(collection = "accounts")
public class Account {
    @Id
    private String id;

    private String accountNumber;
    private String type;
    private String status;
    private double availableBalance;
    private String currency;

    //getters and setters 
}

数据库查询示例

> db.accounts.find({})
{ "_id" : ObjectId("5deb40c43e079db50337b211"), "accountNumber" : "BANK123456", "type" : "savings", "status" : "active", "availableBalance" : 10000.5, "currency" : "USD" }

站台详情：

操作系统：Ubuntu 19.04 LTS

Mongo版本：4.2.1

我的mongo服务器正在我的本地计算机上运行，端口为
27017


这是一个新的mongo安装。
通过执行以下操作进行修复

已删除
/config/MongoAdminConfig.java
/Application.java

@SpringBootApplication
@EnableReactiveMongoRepositories
public class Application {

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

src/main/resources/application.yml

spring:
  data:
    mongodb:
      host: localhost
      port: 27017
      database: projects

我会一直想知道这里到底发生了什么
