RequestMapping in Sprint-boot VAADIN application - spring-boot

Question

I have a Spring-boot VAADIN application with main classes as follows
Application Class
#SpringBootApplication
public class MySpringBootApplication {
public static void main(String[] args) {
SpringApplication.run(MySpringBootApplication.class, args);
}
}
VAADIN-UI Class
#Theme("valo")
#SpringUI
public class MyAppUI extends UI {
#Autowired
private SpringViewProvider viewProvider;
#Override
protected void init(VaadinRequest vaadinRequest) {
final VerticalLayout mainLayout = new VerticalLayout();
setContent(mainLayout);
Navigator navigator = new Navigator(this, mainLayout);
navigator.addProvider(viewProvider);
}
}
VAADIN-View Class
#SpringView(name = "")
public class MyAppView extends VerticalLayout implements View {
#PostConstruct
void init() {
// Some logic here
}
#Override
public void enter(ViewChangeListener.ViewChangeEvent event) {
// Some logic here
}
}
Currently, the application handles the request in root URL i.e. say http://localhost:8080/. But I want the application to handle requests when a parameter is supplied by http://localhost:8080/<parameter_value>. How can I achieve this?
The logic I have to execute is the same in both cases i.e. I want MyAppView to process both root URL request and the one with a parameter value.

VAADIN's getUI().getPage().getLocation().getPath() method can be used to get the parameter value from the URL. This will give everything from '/' in the URL. Sample code is given below:
VAADIN-View Class
#SpringView(name = "")
public class MyAppView extends VerticalLayout implements View {
#PostConstruct
void init() {
// Some logic here
}
#Override
public void enter(ViewChangeListener.ViewChangeEvent event) {
// Remove spaces and also initial '/' in the path
String uriParamValue = getUI().getPage().getLocation().getPath().trim().substring(1);
// Do processing with uriParamValue
}
}
