Question

我正在尝试构建https://spring.io/guides/gs/accessing-data-mongodb/提供的spring boot MongoDB项目，该项目使用的是spring-boot-starter-parent 2.0.0.RELEASE，并获得

堆栈跟踪：

com.mongodb.MongoSocketOpenException: Exception opening socket

... 3 common frames omitted

当我将spring-boot-starter-parent版本更改为1.5.9.RELEASE或1.5.10.RELEASE时，相同的代码工作正常。因此在使用spring data mongo时版本2.0.0.RELEASE有任何问题。

系统详情：

mongod版本：3.4.13

openjdk version＆＃34; 1.8.0_151＆＃34;

我必须首先为spring-boot-starter-parent 2.0.x安装并启动mongodb

假设您使用的是MacOS

# to install mongodb
➜  ~ brew install mongodb 
# To have launchd start mongodb now and restart at login
➜  ~ brew services start mongodb

之后一切都按预期工作：
