Caching with Redis


Spring Caching with Redis

Spring Data Redis project provide an CacheManager implementation for Redis.

Get Redis

Get a copy of Redis from official Redis website.
In most of linux distribution, you can install it from distribution repository directly.
Before you run you codes, make sure it is running.

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, configure a Redis specific CacheManager.
@Override
@Bean
public CacheManager cacheManager() {
 RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate());
 return cacheManager;
}

@Bean
public RedisTemplate redisTemplate() {
 RedisTemplate redisTemplate = new RedisTemplate();
 redisTemplate.setConnectionFactory(jedisConnectionFactory());

 return redisTemplate;
}

@Bean
public JedisConnectionFactory jedisConnectionFactory() {
 // JedisPoolConfig poolConfig=new JedisPoolConfig();
 // poolConfig.set

 JedisConnectionFactory connectionFactory = new JedisConnectionFactory();
 connectionFactory.setHostName("192.168.1.103");
 connectionFactory.setUsePool(true);
 return connectionFactory;
}

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