用Kotlin字符串转义$ {something} [英] Escape ${something} in a Kotlin String

问题描述

定义包含声明模板替换字符的Kotlin字符串的正确方法是什么，但不是将其评估为模板?

What is the correct way of defining a Kotlin string that includes the characters for declaring a template substitution, but not have this evaluated as a template?

例如:"${something}"只是被视为普通字符串.

For example: "${something}" just treated as an ordinary string.

我想使用Spring值注释:

I would like to use the Spring value annotation:

@Value("${some.property}) lateinit var foobar : String?

推荐答案

这对我有用:

val s = "\${foo}"
println("s = ${s}") // prints s = ${foo}

记录的方式也可以正常工作:

val s = "${'$'}{foo}"
println("s = ${s}") // prints s = ${foo}
