Cannot get context-param in web.xml from Spring Boot Controller

I have a simple webapp which use Spring Boot web and I have a web.xml file in src/main/webapp/WEB-INF which contains context-param like this

<context-param>
    <description>Directory containing the configuration files</description>
    <param-name>confDir</param-name>
    <param-value>/opt/rasdaman/etc/</param-value>
</context-param>

In Servlet Controller, I could get the Servlet Context

@Autowired
private ServletContext servletContext;

but when I tried to get the parameter, it returns null

servletContext.getInitParameter("confDir");

when I tried to get the real path to the servletContext

servletContext.getRealPath(File.separator);

it returns

 "..../src/main/webapp/"

How can I get the configuration variable in web.xml?

Thanks

Havent tried it myself but. If you make a Controller implement ServletContextAware I think you can get your context-param from : http://docs.spring.io/spring/docs/3.0.x/javadoc-api/org/springframework/web/context/ServletContextAware.html

The idea would be

public class MyCoolController implements ServletContextAware {


    @Override
    setServletContext(ServletContext servletContext) {
        String confDir = servletContext.getInitParameter("confDir");
    }
}

Give it a shot
