Mongo 尝试自动连接到端口 27017(localhost)答案

【问题标题】：Mongo tries to connect automatically to port 27017(localhost)Mongo 尝试自动连接到端口 27017(localhost)

【问题描述】：

我在 Maven 中使用 Spring Rest 和 Mongo 来创建一个连接到服务器的 Web 服务。问题是我还没有为 Mongo 编写任何代码，它正在尝试连接到 localhost，向我抛出 MongoSocketOpenException。我写的唯一代码是从 main 开始的两行代码。这是堆栈跟踪：

最后我必须声明，尽管出现异常，程序运行良好

提前致谢！

标签： spring mongodb rest spring-boot

【解决方案1】：

Spring Boot 有一个称为“自动配置”的功能。在这种情况下，一旦在类路径中检测到 Mongo 驱动程序，就会使用默认值激活 MongoAutoConfiguration，默认值指向 localhost:27017。如果您不希望这种行为，您现在可以配置 MongoDB 的属性（请参阅http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-mongodb 以获取有效的属性键）或禁用 MongoAutoConfiguration：

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})

【讨论】：

@EnableAutoConfiguration(exclude = { MongoAutoConfiguration.class, MongoDataAutoConfiguration.class}) 如果使用 EnableAutoConfiguration 注解。
我在使用 MongoDB 的异步驱动程序时遇到了同样的问题。排除上述自动配置类似乎没有结果。你知道发生了什么吗？我也对这个问题提出了一个问题，Spring Boot Starter-Web tries to connect to Mongo at startup
这只是为了防止控制台中出现错误日志，但如果在调试模式下启动应用程序，控件仍然会转到 SilentExitExceptionHandler 并抛出 SilentExitException。

【解决方案2】：

在某些情况下，如果您使用的是响应式，您还需要删除 MongoReactiveAutoConfiguration

spring:
  autoconfigure:
    exclude:
      - org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration
      - org.springframework.boot.autoconfigure.mongo.MongoReactiveAutoConfiguration

【讨论】：

【解决方案3】：

当 Mongo DB 未运行时，Spring boot 会抛出此异常。请确保 Mongodb 正在运行。启动 Mongo DB 后，它为我解决了。

【讨论】：

你能帮忙吗，如何在spring boot应用程序中启动MongoDB

【解决方案4】：

对于 springboot，您应该将以下配置添加到您的 application.property

spring.data.mongodb.host=localhost(your mongo server)
spring.data.mongodb.port=27017(mongo port)
