Prise en main de Coherence 12.2.1

La dernière version du DataGrid Java d’Oracle vient de sortir, Coherence 12.2.1. Voici comment démarrer un projet de zéro.

Télécharger le produit

Depuis le site d’Oracle sur http://www.oracle.com/technetwork/middleware/coherence/downloads/index.html

Télécharger les 2 binaires:

  • Coherence Quick install
  • Coherence Quick install Supplemental

Download coherence 12.2

 Installer Coherence

  • Décompresser les 2 archives dans un répertoire commun
  • Installer le package de base dans OracleHome
set COHERENCE_HOME=c:\Oracle\Coherence12.2
java -jar fmw_12.2.1.1.0_coherence_quick.jar ORACLE_HOME=%ORACLE_HOME%
  • Installer les extensions
java -jar fmw_12.2.1.1.0_coherence_quick_supplemental.jar ORACLE_HOME=%COHERENCE_HOME%

Installer les paquets Maven

Cette étape installe les librairies et plugins nécessaires dans votre repository Maven local.

La documentation Oracle est ici: https://docs.oracle.com/middleware/1221/core/MAVEN/config_maven.htm#MAVEN311

cd %COHERENCE_HOME%\oracle_common\plugins\maven\com\oracle\maven\oracle-maven-sync\12.2.1
mvn install:install-file -DpomFile=oracle-maven-sync-12.2.1.pom -Dfile=oracle-maven-sync-12.2.1.jar
mvn com.oracle.maven:oracle-maven-sync:push -Doracle-maven-sync.oracleHome=%COHERENCE_HOME% -DoverwriteParent=true -DtestingOnly=false

Initialiser le projet Maven

Dans le répertoire racine de votre projet, exécuter la création via l’archetype Maven:

mvn archetype:generate -DarchetypeGroupId=com.oracle.coherence.archetype -DarchetypeArtifactId=gar-maven-archetype -DarchetypeVersion=12.2.1-1-0 -DgroupId=fr.middlewareSolutions.coherence -DartifactId=demoA -Dversion=1.0-SNAPSHOT

Le fichier POM de base est alors celui-ci:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 <modelVersion>4.0.0</modelVersion>

 <groupId>fr.middlewareSolutions.coherence</groupId>

 <artifactId>coherence</artifactId>
 <version>[12.2.1,12.2.2)</version>

 </dependencies>

 <build>

</project>

Ajouter un test

Pour dérouler un test JUnit, il est nécessaire de compléter le pom avec

1_ une dépendance JUnit

<dependency>
 <groupId>junit</groupId>
 <artifactId>junit</artifactId>
 <version>4.12</version>
 </dependency>

2_ un contexte Coherence indépendant: src/test/resources/tangosol-coherence-override.xml

<?xml version='1.0'?>

<coherence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://xmlns.oracle.com/coherence/coherence-operational-config"
 xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-operational-config coherence-operational-config.xsd">

 </member-identity>
 <multicast-listener>

 <port>12120</port>
 </multicast-listener>
 </cluster-config>
 <logging-config>
 <severity-level>5</severity-level>
 </logging-config>
 <configurable-cache-factory-config>
 <init-params>
 <init-param>
 <param-type>java.lang.String</param-type>
 <param-value system-property="coherence.cacheconfig">META-INF/cache-config.xml
 </param-value>

 <init-param id="1">
 <param-type>boolean</param-type>
 <param-value system-property="distributed.localstorage">true</param-value>
 </init-param>
 </init-params>
 </configurable-cache-factory-config>
 
</coherence>

3_ une configuration Coherence simple (Local): src/test/resources/META-INF/cache-config.xml

<?xml version="1.0"?>
<cache-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://xmlns.oracle.com/coherence/coherence-cache-config"
 xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-cache-config coherence-cache-config.xsd">
 <caching-scheme-mapping>
 <cache-mapping>
 <cache-name>test-*</cache-name>
 <scheme-name>local</scheme-name>
 </cache-mapping>
 </caching-scheme-mapping>

 <caching-schemes>
 <local-scheme>
 <scheme-name>local</scheme-name>
 </local-scheme>

 </caching-schemes>
</cache-config>

4_ Une classe de test SimpleTest dans src/test/java

package fr.middlewareSolutions.coherence.demoA;

import static org.junit.Assert.*;

import org.junit.Test;

import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;

public class SimpleTest {

 @org.junit.AfterClass
 public void stopCache() {
 CacheFactory.shutdown();
 }
 
 @Test
 public void putASimpleValue() {
 String key = "k1";
 String value = "Hello World!";

 NamedCache&lt;Object, Object&gt; cache = CacheFactory.getCache("test-1");

 cache.put(key, value);
 assertEquals(value, (String) cache.get(key));

 
 }

}

Il ne reste plus qu’a lancer le build:


mvn test
