Caching with GemFire


Spring Caching with Pivotal GemFire

Spring Data Gemfire project provides a CacheManager implementation for Pivotal Gemfire.

Get Gemfire

First you have to get a trial copy from Pivotal Gemfire.
Install it into your system, and make sure it runing.

Enable Caching

Add @EnableCaching(mode=AdviceMode.ASPECTJ) annotation on the configuration class if you are using Java based configuration.
@Configuration
...
@EnableCaching(mode=AdviceMode.ASPECTJ)
public class JpaConfig {...}
Then, specify a CacheManager provider in your configuration. There is a GuavaCacheManager provided by Spring.
@Bean
CacheFactoryBean cacheFactoryBean() {
 return new CacheFactoryBean();
}

@Bean
LocalRegionFactoryBean<String, Conference> localRegionFactory(final GemFireCache cache) {
 return new LocalRegionFactoryBean<String, Conference>() {{
  setCache(cache);
  setName("conference");
 }};
}

@Override
@Bean
public CacheManager cacheManager() {
 GemfireCacheManager _cacheManager= new GemfireCacheManager();
 try {
  _cacheManager.setCache(cacheFactoryBean().getObject());
  Set<Region<?,?>> regions=new HashSet<>();
  regions.add(localRegionFactory(cacheFactoryBean().getObject()).getObject());
  _cacheManager.setRegions(regions);
 } catch (Exception e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 
 return _cacheManager;
}

@Override
@Bean
public KeyGenerator keyGenerator() {
 return new SimpleKeyGenerator();
}
Do not forget to add the spring-data-gemfire dependency in your Maven pom.xml file.
<dependency>
 <groupId>org.springframework.data</groupId>
 <artifactId>spring-data-gemfire</artifactId>
</dependency>

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 upgraded 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-we…

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 &…
