Spring @Value转义冒号(:)为默认值 [英] Spring @Value escape colon(:) in default value

问题描述

我有以下用@Value注释的属性.我有一个使用默认分隔符':"

I have the following property annotated with @Value. I have a default value defined using the default separator of ':"

@Value("${prop.url:http://myurl.com}")

是否可以在http://myurl.com中转义':'，还是必须在配置中定义其他分隔符值.

Is there a way to escape the ':' in http://myurl.com or do I have to define a different separator value in my configuration.

推荐答案

更新: 对于4.2或更高版本的Spring，不需要单引号. Spring将第一个冒号视为特殊字符，并将其余所有都用作单个字符串值.

Update: For spring 4.2 and higher, no single quotes are needed. Spring will see the first colon as special, and use all the rest as a single string value.

对于4.2或更高版本的春季，

For spring 4.2 and higher,

@Value("${prop.url:http://myurl.com}")

对于以前的版本，我相信单引号可以解决问题:

For the previous versions, I believe single quotes will do the trick:

@Value("${prop.url:'http://myurl.com'}")
