Demo

This repository demonstrates the use of Hazelcast as the cache provider for JCache in a Spring boot REST application.

One hazelcast cache called testCache is configured in the hazelcast.xml file. This cache is set up to expire entries after one minute.

Hazelcast is added to the Spring project by adding the following two dependencies to the pom file:

            <dependency>
                <groupId>com.hazelcast</groupId>
                <artifactId>hazelcast</artifactId>
            </dependency>

Usage

To use this demo:

  • Clone the repository

  • Run the following commands

      > mvn clean package
  > java -jar taget/hazelcast-springboot-jcache-1.0-SNAPSHOT.jar --server.port=8083

You'll see a Tomcat server start up. Once everything is started you should see something like the following:

    @@@@> Cache miss! Getting new value
    0 seconds since created. 	 Result: test_1486696868113
    7 seconds since created. 	 Result: test_1486696868113

Around 60 seconds later you should see:

    56 seconds since created. 	 Result: test_1486696868113
    @@@@> Cache miss! Getting new value
    0 seconds since created. 	 Result: test_1486696931133

NOTE: The number at the end of the result value will vary. That is the current time in milliseconds
