我有使用 JBoss Datagrid 停止某些文档并使其可搜索的要求。所以,我正在考虑使用 Hibernate-search,它已经是 JBoss 的一部分。但现在我被困住了。这是我在 JUnit 中生成的简单代码。
@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;
}
}
但我得到了这样的错误。

我想我没有要连接的数据库。这将如何运作?有人告诉我必须使用 JBoss Datagrid。我知道https://docs.jboss.org/hibernate/ogm/3.0/reference/en-US/html_single/但它太新了,几个月前才问世。这完全可以做到吗?
