@RequestMapping with placeholder not working

Question

So i have spend hours to try to get the anwser of this post working:
Overriding RequestMapping on SpringMVC controller

But it really is not working. What I have

Answer 1

I had this problem also and solved it once I realized that a PropertyPlaceholderConfigurer bean wasn't loaded into the context of the module where many of the placeholders existed.

Simple solution was to refactor our externalized configuration. In the end, I moved the @PropertySources definition and PropertyPlaceholderConfigurer bean to a common module and all is well:

@Configuration
@PropertySources(value = {@PropertySource("classpath:app-config.properties")})
public class ExternalizedConfig {

@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
    return new PropertySourcesPlaceholderConfigurer();
}

The request mappings like this work as expected now:

@RequestMapping(value="/${foo.bar.rest_proxy_uri}/**", method = RequestMethod.GET)

In fact, on server startup, you will see the placeholders have been resolved:

2015-05-06 16:21:52 INFO  RequestMappingHandlerMapping:220 - Mapped "{[/restProxy/**],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.http.ResponseEntity<java.lang.String> foo.bar.web.controllers.RestfulFooBarProxyController.proxyGet(javax.servlet.http.HttpServletRequest)
