我从jar生成了Spring-Boot。我想从命令行执行此jar。我明确地将此jar复制到了不在我的Eclipse工作区中的文件夹D:\test中。我还将D:\test的{{1}}文件放在application.properties
我的Spring-Boot主应用程序包含一个PropertySource批注，该批注引用了从命令行提供的变量：
app.title = Testing @SpringBootApplication
@EnableAutoConfiguration
@ComponentScan(basePackages = "com.axian.oxalys.*")
@PropertySource({"file:${app.home}/application.properties"})
public class App {
@Value("${app.title}")
private static String appTitle;
public static void main(String[] args) {
System.out.println("-------------------------------------------");
System.out.println("------------- app property = "+appTitle);
System.out.println("-------------------------------------------");
}
}
是：
application-context.xml因此，当我从<?xml version="1.0" encoding="UTF-8"?>

执行命令行：D:\test时，变量appTitle会为空！那怎么了？
