Spring web Application Context

Question

In my web application I am creating a CustomWebApplicationInitializer which is extending from AbstractAnnotationConfigDispatcherServletInitializer. I need to add another property source for the application. I am doing so in the onStartup method as below by setting the InitParameter in servletContext.

  public class MvcWebApplicationInitializer extends
      AbstractAnnotationConfigDispatcherServletInitializer {
    private static final String[] SERVLET_MAPPINGS = new String[] {"/"};
    private static final String SESSION_COOKIE_PATH = "/";

    @Override
    protected Class<?>[] getRootConfigClasses() {
      return new Class[] {AppConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
      return new Class[] {WebConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
      return SERVLET_MAPPINGS;
    }


    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        servletContext.setInitParameter("contextInitializerClasses", "com.test.myproject.MyTestPropertySourceInitializer");
    }
  }

MyTestPropertySourceInitializer implements ApplicationContextInitializer and checks if the value of a certain property is set to true.

 public void initialize(ConfigurableApplicationContext applicationContext) {
    ConfigurableEnvironment env = applicationContext.getEnvironment();
    Boolean testPropEnabled = (Boolean) env.getProperty("testProperty.enabled", Boolean.class);

I have set that property value to true. But in the logs value is false and it does not process as expected. So I think that by the time the initialize method is called, the property file is not loaded in applicationContext. Please advise how I can get this working. Thanks in advance.

try, by force load the properties file

 public void initialize(ConfigurableApplicationContext applicationContext) {
    ConfigurableEnvironment env = applicationContext.getEnvironment();
    env.getPropertySources().addFirst(new ResourcePropertySource("classpath:application.properties"))

    Boolean testPropEnabled = (Boolean) env.getProperty("testProperty.enabled", Boolean.class);

}
