JSF 2.3: CDI compatible @ManagedProperty

CDI compatible @ManagedProperty

In JSF 2.3, the built-in scope annotations are deprecated, there are some alternatives provided in CDI, eg. ApplicationScoped, SessionScope, RequestScoped, etc.
In JSF 2.2, JSF itself provided a CDI compatible ViewScoped, go here to view more details.
There is an exception, we can not find an alternative for the legacy @ManagedProperty, there is a useful blog entry describe how to created a CDI compatible @ManagedProperty from scratch.
Fortunately, JSF 2.3 provides a built-in CDI implementation.
Let's create a sample to try it.
Create a simple backing bean.
import javax.faces.annotation.ManagedProperty;
//...other imports

@Model
public class BackingBean {

    @Inject
    @ManagedProperty("#{fooBean.bar}")
    private String message;

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }
       
}
NOTE, @ManagedProperty is from package javax.faces.annotation, which is newly added in JSF 2.3.
fooBean is a CDI bean, which has a property named bar.
@Named
public class FooBean {

    private String bar = "bar from FooBean";

    public String getBar() {
        return bar;
    }

    public void setBar(String bar) {
        this.bar = bar;
    }
}
In the facelets template, display the message of BackingBean.
<div>
 CDI managed property: #{backingBean.message} 
</div>
Run this application on Glassfish v5, open your browser and navigate to http://localhost:8080/jsf-managedproperty/managedproperty.faces.

Build a Reactive application with Angular 5 and Spring Boot 2.0

I have created a post to describe Reactive programming supports in Spring 5 and its subprojects, all codes of this article are updated the latest Spring 5 RELEASE, check spring-reactive-sample under my Github account.
In this post, I will create a simple blog system, including:
A user can sign in and sign out.An authenticated user can create a post.An authenticated user can update a post.Only the user who has ADMIN role can delete a post.All users(including anonymous users) can view post list and post details.An authenticated user can add his comments to a certain post. The backend will be built with the latest Spring 5 reactive stack, including:
Spring Boot 2.0, at the moment the latest version is 2.0.0.M7Spring Data MongoDB supports reactive operations for MongoDBSpring Session adds reactive support for WebSessionSpring Security 5 aligns with Spring 5 reactive stack The frontend is an Angular based SPA and it will be generated by Angular CLI.
The source code is hosted on Github, …

Activating CDI in JSF 2.3

Activating CDI in JSF 2.3 When I upgraed my Java EE 7 sample to the newest Java EE 8, the first thing confused me is the CDI beans are not recoganized in Facelects template in a JSF 2.3 based web applicaiton, which is working in the development version, but in the final release version, they are always resolved as null. I filed an issue on Mojarra and discussed it with the developers from communities and the JSF experts.
According to the content of README, In a JSF 2.3 application, to activate CDI support, declaring a 2.3 versioned faces-config.xml and adding javax.faces.ENABLE_CDI_RESOLVER_CHAIN in web.xml is not enough, you have to declare @FacesConfig annotated class to enable CDI.
Here is the steps I created a workable JSF 2.3 applicatoin in Java EE 8.
Create a Java web application, this can be done easily by NetBeans IDE, or generated by Maven archetype, for exmaple.
$ mvn archetype:generate -DgroupId=com.example -DartifactId=demo -DarchetypeArtifactId=maven-archetype-w…

JSF 2.3:Websocket support

Websocket support One of the most attractive features is JSF 2.3 added native websocket support, it means you can write real-time applications with JSF and no need extra effort.
To enable websocket support, you have to add javax.faces.ENABLE_WEBSOCKET_ENDPOINT in web.xml.
<context-param> <param-name>javax.faces.ENABLE_WEBSOCKET_ENDPOINT</param-name> <param-value>true</param-value> </context-param> Hello Websocket Let's start with a simple example.
@ViewScoped@Named("helloBean") publicclassHelloBeanimplementsSerializable { privatestaticfinalLoggerLOG=Logger.getLogger(HelloBean.class.getName()); @Inject@PushPushContext helloChannel; String message; publicvoidsendMessage() { LOG.log(Level.INFO, "send push message"); this.sendPushMessage("hello"); } privatevoidsendPushMessage(Objectmessage) { helloChannel.send(""+ message +" at &…
