Ehcache 3 is used through JSR-107. Here is an example.
Your pom.xml:
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.2.9.RELEASE</version>
</dependency>
<dependency>
<groupId>org.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>3.5.0</version>
</dependency>
<dependency>
<groupId>javax.cache</groupId>
<artifactId>cache-api</artifactId>
<version>1.1.0</version>
</dependency>
Your ehcache.xml (at the root of the classpath):
<?xml version="1.0" encoding="UTF-8"?>
<config
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:jsr107='http://www.ehcache.org/v3/jsr107'
xmlns='http://www.ehcache.org/v3'
xsi:schemaLocation="
http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.4.xsd
http://www.ehcache.org/v3/jsr107 http://www.ehcache.org/schema/ehcache-107-ext-3.4.xsd">
<service>
<jsr107:defaults enable-management="false" enable-statistics="true"/>
</service>
<cache alias="cache">
<resources>
<heap unit="entries">2000</heap>
</resources>
</cache>
</config>
An example app using the cache:
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.jcache.JCacheCacheManager;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.net.URISyntaxException;
import javax.cache.Caching;
@EnableCaching
@Configuration
public class App {
private static int value = 0;
@Bean
public CacheManager cacheManager() throws URISyntaxException {
return new JCacheCacheManager(Caching.getCachingProvider().getCacheManager(
getClass().getResource("/ehcache.xml").toURI(),
getClass().getClassLoader()
));
}
public static void main( String[] args ) {
ApplicationContext context = new AnnotationConfigApplicationContext(App.class);
App app = context.getBean(App.class);
System.out.println(app.incValue());
System.out.println(app.incValue()); // still return 0
}
@Cacheable("cache")
public int incValue() {
return value++;
}
}
