I've taken a look at the form post and reviewed #11277, but it's still not exactly clear to me what the issue is that you are having particularly. Could you please provide more detail, code snippets, etc? Thanks.

String value;

@Override

}

cannot inject test.value from properties file

This is actually a fundamental limitation of @Autowired and @Value (and @Inject and @Resource and @Required for that matter) - because they are themselves processed by BeanPostProcessors, they may not be used within BeanPostProcessor or BeanFactoryPostProcessor types. The latter is what you're attempting to do, and unfortunately it just won't work.

If your B(F)PPs require value or dependency injection, you'll need to wire them up via XML, or altertatively within a @Bean method. Do make sure to mark the @Bean method static if you go that route (see resolution comments on #12917)
