我不能在Springboot-Kotlin中排除MongoAutoConfiguration（MongoSocketOpenException）

Question

我在尝试排除MongoAutoConfiguration时遇到MongoSocketOpenException。我正在尝试连接到远程MongoDB。考虑到我在Kotlin工作，@ EnableAutoConfiguration语法是否正确？

例外：

Answer 1

Kotlin 中没有类似java的数组初始化。它应该是

@EnableAutoConfiguration(exclude = arrayOf(MongoAutoConfiguration::class))

Answer 2

这样更好

@EnableAutoConfiguration(exclude = [MongoAutoConfiguration::class])

Answer 3

如果您使用的是@SpringBootApplication注释而不是@EnableAutoConfiguration，则必须在其中添加注释：

@SpringBootApplication(exclude={MongoAutoConfiguration.class})
