Spring Reactive MongoDB不保存文档

Question

我正在尝试保存一个基本文档，但尽管连接到 mongodb 成功......它似乎不想保存。

应用程序属性

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=legal
spring.data.mongodb.repositories.type=reactive
spring.mongodb.embedded.version=4.0.2

基本接口(interface)和类

interface EventRepository: ReactiveMongoRepository<Event, String>

@Document
class Event(id: String, name: String)

尝试一个简单的保存功能

@Service
class SomeService(val eventRepository: EventRepository)
{
    fun save() = eventRepository.save(Event(UUID.randomUUID().toString(), "hey"))
}

Answer 1

Mono<Event> response = repository.save(Event(UUID.randomUUID().toString(), "hey"));

保存方式的变化

fun save() = eventRepository.save(Event(UUID.randomUUID().toString(), "hey")).subscribe();

您必须在 Mono 引用上调用 subscribe() 方法才能查看日志或详细信息。
