嵌入式 MongoDB 与 Spring 不工作
Embedded MongoDB with Spring not working
我正在尝试使用 WebFlux 和嵌入式 MongoDB 创建一个 Spring 应用程序。但是，即使我的测试运行完美，我也无法启动我的应用程序，因为嵌入式 mongodb 似乎还没有启动。
我得到的异常如下：

我的应用程序属性只是一个空白文件。我的存储库 class 如下：
package com.lorescianatico.driftcoin.repository;
import com.lorescianatico.driftcoin.model.BlockChain;
import org.springframework.data.mongodb.repository.ReactiveMongoRepository;
public interface BlockChainRepository extends ReactiveMongoRepository<BlockChain, String> {
}
如您所见，我正在为 mongodb 使用反应式存储库。我已经尝试通过注释反应存储库激活，但它没有改变异常。我是否遗漏了什么，比如配置或类似的东西？
提前致谢。
您是否在 application.properites
中添加了这些 mongo 属性
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=app1
这篇link将有助于解决您的问题
使用等级时，我遇到了同样的问题，问题出在我的 build.gradle 上，通过更改此行解决了它：
测试编译('de.flapdoodle.embed:de.flapdoodle.embed.mongo')
至
编译('de.flapdoodle.embed:de.flapdoodle.embed.mongo')
所以问题必须在你的 pom 中，嵌入式 mongodb 没有被设置。
您的嵌入式 mongodb 设置为在您测试时使用：
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<scope>test</scope>
</dependency>
从那里删除测试范围，以便您可以在运行时使用它：
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
</dependency>
我通过在 VM 上安装 mongo 然后 运行 启动 Spring 启动实例解决了这个问题。
对我来说，嵌入式 mongo 驱动程序 (de.flapdoodle.embed.mongo) 无法正常工作，所以我删除了依赖项。
安装 Mongo & 运行 它
- sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
- 回声"deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
- sudo apt-get 更新
- sudo apt-get install -y mongodb-org
- sudo 服务mongod 重启
运行 Spring 引导应用程序
发布我的解决方案，因为它可能会对某人有所帮助 - 我已经将版本添加到 de.flapdoodle.embed.mongo 依赖项并且它做了一个技巧：
使用这个：
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<version>2.2.0</version>
<scope>test</scope>
</dependency>
而不是这个：
