Question

我正在使用Spring Boot项目设置MongoDB。但是，当我通过gradle编译我的应用程序并运行jar时，它会抛出以下错误：

2018-03-26 16:17:00.634  INFO 9321 --- [localhost:27017] org.mongodb.driver.cluster               : Exception in monitor thread while connecting to server localhost:27017

在运行jar之前，我已经通过mongod在我的mac上运行了mongodb，它在终端I NETWORK [initandlisten] waiting for connections on port 27017上显示以下消息

另外，我的spring项目的applications.properties文件是空白的。任何关于如何诊断这个问题的线索都将不胜感激！

Answer 1

经过近一天的调试，Spring Boot项目与localhost上的mongodb安装成功连接。仍然不确定究竟是什么导致了这个问题，但这是我调试它的方式：

1）通过将实例绑定到所有接口来运行mongodb：

g2

2）我按如下方式构建了我的应用程序的配置文件：

sudo mongod —bind_ip_all

然后将此配置文件读入主应用程序文件：

@Configuration
@EnableAutoConfiguration(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
@ComponentScan
public class AppConfiguration {
}

最后，将application.properties文件留空。

Spring Boot显示＆＃34;连接被拒绝＆＃34;连接mongoDB时出错
