在构建时获取maven属性

Question

我正在尝试pom.xml根据文档从构建时获取一些属性.

我的目标是在我的Spring启动中注入它们,application.properties但属性不会被替换.

这是我的代码

的pom.xml

SRC \主\资源\ application.properties

application.version=${project.version}

我错过了什么吗？这应该有用吗？

如果您使用的是spring boot parent pom,则默认占位符已重新配置为不与spring本身的$ {}语法冲突.

要替换maven属性,请使用@ - so @ project.version @而不是$ {project.version}.

默认情况下启用application.properties文件的过滤.
