Spring application URL in scheduled job

Question

Is it possible to get the application URL in spring scheduled job (@Scheduled annotated)? I want to create a job which sends an email with URL to specific page on the application, let's say on http://localhost:8080/appName/some/specific/url. The problem is that the part http://localhost:8080/ will be different in each environment (local,dev,production etc).

Is there any simple way to get a base URL in server-side method which is executed by spring scheduler?

Answer 1

I do that with a properties file. This tutorial tells you how you can do it.

The only complex part is you need a way to change the value the properties file is referencing for each of your different environments.

Answer 2

There is no direct way to get the base url within your scheduler. You may want to look at work arounds for this, like

1. Use a properties file to store url for each environment

2. Have a Configurartion bean which implements ServletContextAware. This bean would be automatically notified when a web context is initialised.

   public class AppConfig implements ServletContextAware{

       private String baseUrl;
   
       public String getBaseUrl(){ 
              return baseUrl; 
       }
   
       public void setServletContext(ServletContext servletContext){
           this.baseUrl=servletContext.getRealPath("/");
       }
   }
