6.3.2. Enabling Infinispan Query DSL-based Queries
In library mode, running Infinispan Query DSL-based queries is almost identical to running Lucene-based API queries. Prerequisites are:
- All libraries required for Infinispan Query (see Section 2.1.1, “Infinispan Query Dependencies” for details) and
infinispan-query-dsl.jarin the classpath. - indexing enabled for caches.
- annotated POJO cache values.
As an alternative to .jar files, the Maven dependency can be used:
<dependency>
<groupId>org.infinispan</groupId>
<artifactId>infinispan-query-dsl</artifactId>
<version>${infinispan.version}</version>
</dependency>
The following example shows how to enable indexing:
ConfigurationBuilder cfg = new ConfigurationBuilder(); cfg.indexing().enable(); DefaultCacheManager cacheManager = new DefaultCacheManager(cfg.build()); Cache cache = cacheManager.getCache();
The following is an example of an annotated entity:
@Indexed
public class User {
@Field(store = Store.YES, analyze = Analyze.NO)
private String name;
@Field(store = Store.YES, analyze = Analyze.NO, indexNullAs = Field.DEFAULT_NULL_TOKEN)
private String surname;
@IndexedEmbedded(indexNullAs = Field.DEFAULT_NULL_TOKEN)
private List addresses;
// .. the rest omitted for brevity
}
