15.2. Using the Infinispan CDI Module

The Infinispan CDI module can be used for the following purposes:

To configure and inject Infinispan caches into CDI Beans and Java EE components.
To configure cache managers.
To control storage and retrieval using CDI annotations.

15.2.1. Configure and Inject Infinispan Caches

15.2.1.1. Inject an Infinispan Cache
复制链接

An Infinispan cache is one of the multiple components that can be injected into the project's CDI beans.

The following code snippet illustrates how to inject a cache instance into the CDI bean:

public class MyCDIBean {
    @Inject
    Cache<String, String> cache;
}

public class MyCDIBean {
    @Inject
    Cache<String, String> cache;
}

15.2.1.2. Inject a Remote Infinispan Cache
复制链接

The code snippet to inject a normal cache is slightly modified to inject a remote Infinispan cache, as follows:

public class MyCDIBean {
    @Inject
    RemoteCache<String, String> remoteCache;
}

public class MyCDIBean {
    @Inject
    RemoteCache<String, String> remoteCache;
}

15.2.1.3. Set the Injection's Target Cache
复制链接

The following are the three steps to set an injection's target cache:

Create a qualifier annotation.
Add a producer class.
Inject the desired class.

15.2.1.3.1. Create a Qualifier Annotation
复制链接

To use CDI to return a specific cache, create custom cache qualifier annotations as follows:

@javax.inject.Qualifier
@Target({ElementType.FIELD, ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SmallCache {}

@javax.inject.Qualifier
@Target({ElementType.FIELD, ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SmallCache {}

Toggle word wrap

Use the created @SmallCache qualifier to specify how to create specific caches.

15.2.1.3.2. Add a Producer Class
复制链接

The following code snippet illustrates how the @SmallCache qualifier (created in the previous step) specifies a way to create a cache:

import org.infinispan.configuration.cache.Configuration;
import org.infinispan.configuration.cache.ConfigurationBuilder;
import org.infinispan.cdi.ConfigureCache;
import javax.enterprise.inject.Proces;

public class CacheCreator {
    @ConfigureCache("smallcache")
    @SmallCache
    @Produces
    public Configuration specialCacheCfg() {
        return new ConfigurationBuilder()
                   .eviction()
                       .strategy(EvictionStrategy.LRU)
                       .maxEntries(10)
                   .build();
    }
}

import org.infinispan.configuration.cache.Configuration;
import org.infinispan.configuration.cache.ConfigurationBuilder;
import org.infinispan.cdi.ConfigureCache;
import javax.enterprise.inject.Proces;

public class CacheCreator {
    @ConfigureCache("smallcache")
    @SmallCache
    @Produces
    public Configuration specialCacheCfg() {
        return new ConfigurationBuilder()
                   .eviction()
                       .strategy(EvictionStrategy.LRU)
                       .maxEntries(10)
                   .build();
    }
}

The elements in the code snippet are:

@ConfigureCache specifies the name of the cache.
@SmallCache is the cache qualifier.

Report a bug

15.2.1.3.3. Inject the Desired Class
复制链接

Use the @SmallCache qualifier and the new producer class to inject a specific cache into the CDI bean as follows:

public class MyCDIBean {
    @Inject @SmallCache
    Cache<String, String> mySmallCache;
}

public class MyCDIBean {
    @Inject @SmallCache
    Cache<String, String> mySmallCache;
}
