Question

我在tomcat的startUp.bat中设置了一个jvm arg JAVA_OPTS=-Dblah.env=Something。 arg用在战争的罐子里，它给了我一个java.lang.IllegalArgumentException: Could not resolve placeholder。当我通过run-app运行它时，我没有这个问题。

结构：在tomcat中运行战争，战争有一个试图@PropertySource({"classpath:blahClient${blah.env}.properties"})并获得'无法解决占位符'的jar

注意：我的resources.groovy中也有一行类似于：

blahClientConfig(BlahClientConfig) {
        application.refresh()
    }

堆栈追踪：

为什么jar没有看到jvm arg blah.env？

Answer 1

当我应该JAVA_OPTS=-Dblah.env=Something

时，我set JAVA_OPTS=-Dblah.env=Something的问题变成了一个愚蠢的问题

当warred up时，占位符未在jar中的@PropertySource注释中解析
