使用 MongoRepository 保存/插入时出现 StackOverflowError

问题描述

我正在尝试使用 mongo 存储库将包装键值类保存/插入到我的 mongoDB 中。

我试图保存的模型是：

@Data
@AllArgsConstructor
@Document(collection = "futureTask")
public class FutureTask {

    @Id
    private Configuration configuration;
    private ScheduledFuture<?> future;
}

存储库实现如下：

public interface FutureTaskRepository extends MongoRepository<FutureTask,Configuration> {
    FutureTask findByConfiguration(Configuration configuration);

    boolean existsByConfiguration(Configuration configuration);
}

FutureTaskRepository 的调用如下：

ScheduledFuture<?> future = this.schedule(new RunnableTask(configuration),new crontrigger(configuration.getCron()));
FutureTask futureTask = new FutureTask(configuration,future);

futureTaskRepository.insert(futureTask);

我收到以下错误：

解决方法

monoDB 似乎在像这样持久化对象方面存在问题。 通过使用 synchronizedCollection 存储创建自定义存储库来解决。现在不使用 mongoDB 或任何其他数据库。

select 
    Name,concat_ws('.',max(transform(split(Version,'\\.'),x -> int(x)))) as Version 
from mytable 
group by Name
