You don’t have to read that guide to walk through this one, but you can if you wish.
If you started with a fresh project, then add the following entity and repository objects and you’re good to go.
You can use any build system you like when building apps with Spring, but the code you need to work with Maven is included here. UI; @Spring UI @Theme("valo") public class Vaadin UI extends UI Although many Vaadin components lazy load the data from the server to the browser, this solution above keeps the whole list of data in the server memory. Spring Component; import com.vaadin.spring.annotation. package hello; import org.springframework.beans.factory.annotation.
If you’re not familiar with Maven, refer to Building Java Projects with Maven. To save some memory, you could show only the topmost results, use paging or provide a lazy loading data provider using set As Vaadin UIs are just plain Java code, there is no excuse to not write re-usable code from the beginning.
That means the listener does not react immediately after the resize but a random time later.
The solution is to synchronize on the application if it is bound, but if it is not yet bound then synchronize on the component itself.
There are a number of tricky details to take care of though: what if the application becomes bound , which is intentional.
I describe a technique for updating the application display in response to asychronous events.
My own use-case was handling service binding/unbinding events in OSGi, but the technique would equally apply to message processing applications, etc.
