我在SPRING_PROFILES_ACTIVE本地 linux 机器上设置了环境变量：
$ echo $SPRING_PROFILES_ACTIVE
development,develop,devel,dev
在我的 servlet 初始化程序中，我设置了一个默认配置文件，因为我没有通过扩展AbstractDispatcherServletInitializer和覆盖在我的生产机器上设置任何变量createRootApplicationContext：
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
StringBuilder sb = new StringBuilder();
for (String s : rootContext.getEnvironment().getActiveProfiles()) {
sb.append(s).append(",");
}
log.debug("Active Profiles: " + sb.toString());
sb = new StringBuilder();
for (String s : rootContext.getEnvironment().getDefaultProfiles()) {
sb.append(s).append(",");
}
log.debug("Default Profiles: " + sb.toString());
rootContext.getEnvironment().setDefaultProfiles("production");
sb = new StringBuilder();
for (String s : rootContext.getEnvironment().getActiveProfiles()) {
sb.append(s).append(",");
}
log.debug("Active Profiles: " + sb.toString());
sb = new StringBuilder();
for (String s : rootContext.getEnvironment().getDefaultProfiles()) {
sb.append(s).append(",");
}
log.debug("Default Profiles: " + sb.toString());
return rootContext;
这就是输出：
DEBUG c.e.WebApplicationInitializer - Active Profiles:
DEBUG c.e.WebApplicationInitializer - Default Profiles: default,
DEBUG c.e.WebApplicationInitializer - Active Profiles:
DEBUG c.e.WebApplicationInitializer - Default Profiles: production,
为什么没有有效的个人资料？

我通过在以下位置创建文件导出了环境变量/etc/profile.d：
DEBUG c.e.WebApplicationInitializer - System.getenv("SPRING_PROFILES_ACTIVE"): null
