项目需要提供一个当前项目版本号的接口。直接获取 pom 文件中的版本号

步骤：

1、application.properties 文件version=${project.version}2、类中@Value("${version}")private String version;复制代码

但是：Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'project.version' in value "${project.version}"

我的 pom 文件：

解决：If you are using the spring boot parent pom the default placeholders have been re-configured to not conflict with the ${} syntax of spring itself.

To replace the maven properties use @ - so @project.version@ instead of ${project.version}.

filtering of the application.properties file is enabled by default.

application.properties 文件

version=@project.version@
