Example 1 with ServiceInitEvent

use of com.vaadin.flow.server.ServiceInitEvent in project flow by vaadin.

the class TestingServiceInitListener method serviceInit.

@Override
public void serviceInit(ServiceInitEvent event) {
    initCount.incrementAndGet();
    event.addRequestHandler((session, request, response) -> {
        requestCount.incrementAndGet();
        return false;
    });
    event.addDependencyFilter((dependencies, context) -> {
        // used by DependencyFilterUI
        if (dependencies.stream().anyMatch(dependency -> dependency.getUrl().startsWith("replaceme://"))) {
            List<Dependency> newList = new ArrayList<>();
            newList.add(new Dependency(Dependency.Type.HTML_IMPORT, "frontend://com/vaadin/flow/uitest/ui/dependencies/filtered.html", LoadMode.EAGER));
            dependencies.stream().filter(dependency -> !dependency.getUrl().startsWith("replaceme://")).forEach(newList::add);
            dependencies = newList;
        } else // used by BundledTemplateInTemplateWithIdView
        if (dependencies.stream().anyMatch(dependency -> dependency.getUrl().startsWith("bundle://"))) {
            List<Dependency> newList = new ArrayList<>();
            newList.add(new Dependency(Dependency.Type.HTML_IMPORT, "frontend://com/vaadin/flow/uitest/ui/template/BundleIdTemplate.html", LoadMode.EAGER));
            dependencies = newList;
        }
        return dependencies;
    });
}

Example 2 with ServiceInitEvent

use of com.vaadin.flow.server.ServiceInitEvent in project flow by vaadin.

the class BundleFilterInitializer method readBundleDependencies.

            for (int i = 0; i < bundledFiles.length(); i++) {
                String bundledFile = bundledFiles.getString(i);
                if (servlet.getResource(es6ContextPathResolver.resolveVaadinUri(es6Base + bundlePath)) == null) {
                    throw new IllegalArgumentException(String.format("Failed to find bundle at context path '%s', specified in manifest '%s'.

                }
                importToBundle.computeIfAbsent(bundledFile, key -> new HashSet<>()).add(bundlePath);
