如何在JBoss數據網格中使用hibernate-search？

我有這個要求，使用JBoss Datagrid來停止一些文件，並使其可搜索。所以，我正在考慮使用已經是JBoss一部分的Hibernate-search。但現在我卡住了。這是我在JUnit中生成的一個簡單代碼。如何在JBoss數據網格中使用hibernate-search？

@Test 
public void testName() throws Exception { 
    Cache<Object, Object> c = new DefaultCacheManager().getCache(); 
    c.put("id", new ProductDG("ean", "desc", newArrayList("image1"))); 

    ProductDG product = (ProductDG) c.get("id"); 
    assertTrue(product.getEAN().equals("ean")); 

    SessionFactory factory = new AnnotationConfiguration().buildSessionFactory(); 
    Session session = factory.openSession(); 

    FullTextSession fts = getFullTextSession(session); 
    fts.index(product); 

} 


@Indexed(index="Product") 
class ProductDG { 
    private String EAN; 
    private String description; 

    private List<String> images; 

    ProductDG(String EAN, String description, List<String> images) { 
     this.EAN = EAN; 
     this.description = description; 
     this.images = images; 
    } 

    String getEAN() { 
     return EAN; 
    } 

    String getDescription() { 
     return description; 
    } 

    List<String> getImages() { 
     return images; 
    } 
}

但我得到這樣的錯誤。

我在想我沒有數據庫連接到。這將如何工作呢？有人告訴我必須使用JBoss Datagrid。我知道https://docs.jboss.org/hibernate/ogm/3.0/reference/en-US/html_single/，但它太新了，它剛剛在幾個月前出來。這可以完成嗎？

JBoss Data Grid使用Hibernate Search是正確的，但它僅適用於索引和查詢定義：您不需要通過「傳統」Hibernate Session使用它。

你不需要啓動的SessionFactory
你甚至不需要在classpath
你使用註解從Hibernate Search的

爲了使Hibernate的ORM罐子一個受你的域名啓發的例子，使用它你只需要在configuration of the Cache中啓用索引。

@Test 
public void testName() throws Exception { 
    Cache<Object, Object> c = new DefaultCacheManager("configuration-file.xml").getCache(); 
    c.put("id", new ProductDG("ean", "desc", newArrayList("image1"))); 
    //at this point your Product is already indexed (assuming you don't use transactions) 

    //Using the MatchAllDocsQuery we'll get a list of all instances: 
    CacheQuery query = searchManager.getQuery(new MatchAllDocsQuery(), ProductDG.class); 

    // Execute Query 
    List objectList = query.list(); 

    for (Object prod : objectList) 
     System.out.println(prod); 

}

你最後的問題是關於Hibernate OGM。是的，這是可以做到很好，但你可能想閱讀的文檔版本4：
