示例1: serviceInit

@Override
public void serviceInit(ServiceInitEvent event) {
ValoDependencyFilter dependencyFilter = new ValoDependencyFilter();
if (dependencyFilter.hasValoWebJar()) {
event.addDependencyFilter(dependencyFilter);
}
VaadinServletService service = (VaadinServletService) event.getSource();
WebApplicationContext applicationContext = WebApplicationContextUtils
.findWebApplicationContext(
service.getServlet().getServletContext());
String apiKey = applicationContext.getEnvironment()
.getProperty("map.apikey");
if (apiKey == null) {
throw new RuntimeException(
"Configure a map.apikey in your application.properties");
}
event.addBootstrapListener(new BootstrapListener() {
@Override
public void modifyBootstrapPage(BootstrapPageResponse response) {
Element head = response.getDocument().head();
head.appendElement("meta").attr("name", "viewport")
.attr("content", "width=device-width, initial-scale=1");
// Flow sets element properties too late for google-map to get
// the right API key. As a temporary workaround, we put our key
// in the map's prototype instead.
