Integrating Spring and JSF

It got me thinking: Where are we with JSF? If we remove JavaScript, we can see the decline started around This post tries to understand the current state of JSF, and whether there is still a place for JSF in modern development. They let you quickly get started on projects, have plenty examples, and are especially suited for a team or for projects where developers lack frontend skills. The current release of JSF is 2. They do make the concession that the web model is getting more prominence in later versions of JSF.

There were rebuttals against this post, particularly relating to more recent JSF versions, but it has contributed to JSF being regarded as a difficult framework to use. What's marmite? It's a yeast extract that you spread on toast. Some people love it, some hate it, but there is no middle ground. The reason I like JSF is that you can access good quality components that are mature and well-documented. It also has the advantage of allowing teams that are weak on frontend skills to develop professional looking websites.

The JSF model has fallen out of favor. This approach can often scale better than JSF. The StackOverflow blog post shows it's not all plain sailing in the frontend JavaScript world. The frameworks suffer from relatively short lifespans, and although there are migration strategies, you do run the risk of your javascript framework being obsolete.

JSF has the advantage of being a mature model in this respect. It's also worth remembering that if your team is lacking in frontend skills, then JSF will help you quickly deliver a professional-looking website.

See the original article here. Over a million developers have joined DZone. Let's be friends:. DZone 's Guide to. With JavaScript-based frameworks dominating much of the web development world these days, is Java EE's JSF still relevant, and should you use it for your next project?This article provides an introduction on how Spring and Java Server Faces Technologies can be integrated. It covers the necessary details of both Spring and JSF Technology in the initial section in the context of Integration.

Later on it moves towards the concept of Variable Resolvers which help in easing the integration between the two technologies. Then a full-fledged sample application is followed to get a greater feel and understanding of the integration.

Before getting into the details of how Sping JSF Integrationit is important to know a bit about basic details. The following section will talk about how the base architecture is structured for both Spring and JSF in the context of integration. Spring is a framework that supports of Inversion of Control.

In Spring terminology, Beans or Spring Beans are nothing but regular java classes. It is possible to externalize the state of Bean objects by specifying them in the Xml file. A spring Bean has a dedicated life-cycle and it passes through various phases. An example bean called Person is as follows. The above example defines a Spring Bean of type Person with an identifier personBean.

It also defines a simple property called name with value Anonymous. It is also possible to relate compound values like references to other object and collection-like set, map, list values as the following code snippet will illustrate that.

Note that in the above example, we have declared two employee objects with identifiers employee1 and employee2. We want these two employee objects to be associated with the manager object. This is an example of a composite relationship, since we are relating Manager to Employees. This is achieved through the reference tag within the property declaration. A client request is directly mapped to an Action in the Web tier, which means that the event-handling mechanism resembles the one what we see in Swings or AWT.

These managed beans are responsible for handling all types of actions in a Web Application. How a UI component is associated with a particular action is easily configurable in Xml file. The following code shows the declaration of a managed bean in JSF. A managed bean is also a regular Java class in JSF and it is configured in faces-config. Now that we have seen about Spring and JSF, let us see about Integration and what component gets integrated.

Precisely, the Spring Bean what we have configured in the Xml file can be directly referred in the faces-config. Let us further clarify this. But for the integration to work, we need to know only about Spring Resolvers.

The following section tries to provide an overview about Spring Resolvers. More specifically given an identifier the JSF framework tries to construct and associate the object with the identifier. Going back to the declaration of managed beans.

In the above declaration, we have an identifier or variable called timerBean. The aim of a JSF Resolver implementation should be to associate an object of type net. TimerBean to timerBean. The JSF implementation will simply throw an error telling that the variable cannot be resolved. Let us see what exactly the sample is all about.Developers describe Java EE as " The standard in community-driven enterprise software ". It is developed using the Java Community Process, with contributions from industry experts, commercial and open source organizations, Java User Groups, and countless individuals.

It offers a rich enterprise software platform and with over 20 compliant implementations to choose from. On the other hand, Spring Boot is detailed as " Create Spring-powered, production-grade applications and services with absolute minimum fuss ".

Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss.

Most Spring Boot applications need very little Spring configuration. Spring Boot is an open source tool with Here's a link to Spring Boot's open source repository on GitHub.

I use Spring-Boot because it almost let you get things done quickly for a JVM-target project, with auto configuration components and dependency management starters. It is almost perfectly tailored for microservices applications development with a single unit deployment artifact JAR along with support for Service Registry and Discovery, Circuit Breaker pattern Coming to day-to-day development, Spring-Boot enjoys a great community so you can get support, direction, focused guidance from almost everywhere.

We are in the process of building a modern content platform to deliver our content through various channels.

We decided to go with Microservices architecture as we wanted scale. Microservice architecture style is an approach to developing an application as a suite of small independently deployable services built around specific business capabilities.

You can gain modularity, extensive parallelism and cost-effective scaling by deploying services across many distributed servers. We also decided to use Event Driven Architecture pattern which is a popular distributed asynchronous architecture pattern used to produce highly scalable applications.

The event-driven architecture is made up of highly decoupled, single-purpose event processing components that asynchronously receive and process events. To build our Backend capabilities we decided to use the following: 1. Microservices - Java with Spring BootNode.

IQ 26: Whats the difference between Spring vs SpringBoot?

AngularJS lets you write client-side web applications as if you had a smarter browser. It automatically synchronizes data from your UI view with your JavaScript objects model through 2-way data binding. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.Comment In such debates people form two groups consisting of evangelists, architects and hard core fans of one platform and debate endlessly.

Those who participate in the debates may be architects who are responsible for platform selection. But what would developers think about this Spring vs JavaEE debate?

Business sometimes political Aspects In many organizations technology selection may not completely depends on developers choice. In addition to that, large enterprises also considers the following aspects while choosing the technology platform:. As a developer I can hardly influence the decision making process for any of the above aspects, especially when I am a developer in offshore development center.

So I don't worry too much about these things. Doesn't Spring and CDI behaves similarly when:. As long as they are behaving similarly I don't care whether they are implemented in more typesafe manner or used String based mappings in their internal implementations. How can one be expert in Spring and can't understand JavaEE and vice-versa?? How much time it can take for a Spring expert to learn JavaEE??!! I think by now many people should have realized that success of a technology may not be completely depends on its merits, but also based on developers adoption.

The most important thing to realize is "Not every software developer is a rock star developer. There are more average joe developers than passionate, tech ninjas". So in order to people adapt any framework it should be "Average Joe Developer" friendly. I think Spring is doing pretty good job at it by providing more tools like SpringBoot, User Guides etc. Also think about various templates provided by Spring which makes easy to do things without worrying about boilerplate coding.

I came across few JavaEE based frameworks like Picketlink which addresses Security requirements, but I felt it is much more complex than it should be. The difference is which is giving more out-of-the-box to average joe developer.Developers describe jsf as " It is use for building component-based web interfaces ". It is used for building component-based user interfaces for web applications and was formalized as a standard through the Java Community.

Be the first to leave a con. What are the cons of using Spring?But, as it excelled as a starting point for applications based on the Spring framework, many have started to wondering how to integrate JavaServer Faces JSF with Spring Boot.

In this article we are going to put all the moving pieces together, and build a small application that enable users to list and persist products to a database. JavaServer Faces JSF is a Java specification that promotes component-based user interface development for web applications. For example, let's say that we wanted to show an HTML table of products.

To do so, we would need an XML file with the following content:. In this case, the view would be rendered by using the h:dataTable component, with the help of a backing bean called productListControllerwhich would generate the HTML response for the requester.

Developing JSF applications with Spring Boot

After rendering the webpage, JSF would retain the state of the view on the server-side to allow future interaction. For starters, we will fork and clone the GitHub repo specially created for this article.

We could also use the Spring Initilizr webpage, which is easy and intuitive. But, as the application that we will build will have some other dependencies like HSQLDB and Flywayit will be easier to start with the fork. Having the application properly imported on our IDEthe first thing we will do is to add a few dependencies. Let's open the pom. From top to bottom, let's demystify what these dependencies are. The first two dependencies, myfaces-api and myfaces-implare the JSF interface specification -api and implementation -impl.

After that there are three dependencies with org. Therefore we will use Rewrite to achieve intuitive, bookmarkable, and pretty URLs. This framework will help us to create beautiful user interfaces easily. While we have the pom. This configuration is important because Rewrite isn't prepared to scan for configurations on non-classical web applications i. So we need to tweak the build process a little to help Rewrite fulfill its purpose.

Next, we will create two XML files. The first one, called web. Usually, on a regular Spring Boot application, we wouldn't need this file.

But, since we are going to use JSFwe need to configure the FacesServlet servlet and a couple of listeners. The first two elements in this file are responsible for setting FacesServlet up and configuring it.

The last two elements, the listener elements, are responsible for integrating JSF into the Spring context. The second XML file that we need is called faces-config. All this file does is to register an ELResolver i. With it we can use Spring managed beans in the JSF context. As the last step to configure JSF with Spring Boot, we need to update the Application class of our project to create two more beans. This is done by configuring this class as follows:. Having both XML files created, the dependencies properly imported, and the Application class configured, we are ready to start developing JSF applications on Spring Boot.

As we are going to develop a simple application that lists and persists products, we are going to start by creating the Product entity.

For starters, create the Product. This entity will have the following code:. You probably noted that your IDE started complaining about the Data annotation.
