java - 在 Spring 5 中将 Query dsl 与 Reactive Mongo Repository 集成

Question

在我能够使用 QuerydslPredicateExecutor 扩展我的 mongo 存储库之前，Spring 5 附带了 spring data mongo 的响应式(Reactive)实现

 @Repository
 public interface AccountRepo extends MongoRepository<Account,String> 
 ,QuerydslPredicateExecutor<Account>

如果我尝试这个

 @Repository
 public interface AccountRepo extends
 ReactiveMongoRepository<Account,String>,
 QuerydslPredicateExecutor<Account>

我的应用程序无法启动它，因为:

原因:org.springframework.data.mapping.PropertyReferenceException:找不到帐户类型的属性!

有没有办法解决这个问题

这是帐户类别

package com.devop.models;

import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document
@Data
public class Account {
@Id
String id;

String accountName;

String accountNumber;

String schemeCode;

String openDate;

String accountCategory;

String accountCurrency = "Naira";

String accountSecondaryCategory;

String receiveSmsAlert;

String recieveEmailAlert;

String cifId;

}

这里是AccountRepo接口(interface)

 package com.devop.mongoRepo;

 import com.devop.models.Account;
 import org.springframework.data.mongodb.repository.*;
 import org.springframework.data.mongodb.repository.support*;
 import org.springframework.data.querydsl.QuerydslPredicateExecutor;
 import org.springframework.stereotype.Repository;
 import reactor.core.publisher.Flux;
 import reactor.core.publisher.Mono;

 @Repository
 public interface AccountRepo extends 
 ReactiveMongoRepository<Account,String> 
 ,QuerydslPredicateExecutor<Account> {

Flux<Account> findAccountByAccountNameContains(String accountName);
Mono<Account> findAccountByAccountNumberEquals(String accountNumber);

}

您可以使用ReactiveQuerydslPredicateExecutor。有关更多信息，请参阅示例 https://github.com/spring-projects/spring-data-examples/tree/master/mongodb/querydsl
