JPA 2.1: Overview


JPA 2.1: Overview

JPA 2.1 brings a series of small improvements.
I have written some posts to introduce them one by one.
JPA 2.1 also includes some RDBMS improvements, such as supports Store Procedure, and adds function in JPQL. I am not a big fan of RDBMS, so these are not so attractive for me.
In this version, some features are still not perfect. As I motioned, the schema generation scripts strategy does not include a Hibernate equivalent UPDATE. Secondly, the CDI support is omitted in the @Converter and @Entity classes.
The JPA expert group should consider more about NoSQL support. Hear the voice from Hibernate community(there is a Hibernate OGM project for NoSQL, now supports Mongo, JBoss Infinispan) and other JPA providers, especially DataNucleus which has excellent NoSQL support.
The sample codes are hosted on my github.com account, check out and play it yourself.

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.
