在Spring Boot中在Yaml中转义Map键中的点

问题描述

我有以下yml配置:

foo:
  bar.com:
    a: b
  baz.com:
    a: c

在下一个类中，Spring尝试使用键"bar"和"baz"注入地图，将点作为分隔符:

With a following class Spring tries to inject map with keys 'bar' and 'baz', treating dots as separator:

public class JavaBean {
    private Map<String, AnotherBean> foo;
(...)
}

我尝试引用密钥(即"bar.com"或"bar.com")，但无济于事-仍然是同样的问题.有办法解决吗?

I have tried quoting the key (i.e. 'bar.com' or "bar.com") but to no avail - still the same problem. Is there a way around this?

推荐答案

@fivetenwill的答案的稍作修订，该版本在Spring Boot 1.4.3上对我有效.

A slight revision of @fivetenwill's answer, which works for me on Spring Boot 1.4.3.RELEASE:

foo:
  "[bar.com]":
    a: b
  "[baz.com]":
    a: c

您需要将括号括在引号内，否则YAML解析器基本上会在到达Spring之前将其丢弃，并且它们不会成为属性名称.

You need the brackets to be inside quotes, otherwise the YAML parser basically discards them before they get to Spring, and they don't make it into the property name.
