通过实现ServletContextListener接口读取该键值对中的值，在web应用程序初始化的时候，调用 ServletContextListener的contextInitialized()方法，重写该方法，实现读取操作：

public class AppListener implements ServletContextListener {


public void contextInitialized(ServletContextEvent sce) {
   try {
      ServletContext sc = sce.getServletContext();
      sc.getInitParameter("spring.profiles.active");  

   } catch(Exception e) {
      
   }
}

  public void contextDestroyed(ServletContextEvent arg0) {

  }
}
