Infinispan搜索继承搜索映射配置

Question

我有简单的代码，测试在英菲尼斯潘搜索引擎。

public class InifinispanTest {

    private static class DemoA {
        private Long id;

        public Long getId() {
            return id;
        }

        public void setId(Long id) {
            this.id = id;
        }
    }

    private static class DemoB extends DemoA {
        private String value;

        public String getValue() {
            return value;
        }

        public void setValue(String value) {
            this.value = value;
        }
    }

    public static void main(String[] args) throws IOException {
        SearchMapping mapping = new SearchMapping();
        mapping.entity(DemoB.class).indexed().providedId()
               .property("id", ElementType.METHOD).field();

        Properties properties = new Properties();
        properties.put(org.hibernate.search.Environment.MODEL_MAPPING, mapping);
        properties.put("hibernate.search.default.directory_provider", "ram");
        properties.put("hibernate.search.default.indexmanager", "near-real-time");

        Configuration infinispanConfiguration = new ConfigurationBuilder()
                .indexing()
                .enable()
                .indexLocalOnly(true)
                .withProperties(properties)
                .loaders().passivation(true).addFileCacheStore()
                .build();

        DefaultCacheManager cacheManager = new DefaultCacheManager(infinispanConfiguration);

        final Cache<Integer, DemoB> cache = cacheManager.getCache();

        for (int i = 0; i < 10000; i++) {
            final DemoB demo = new DemoB();
            demo.setId((long) i);

            cache.put(i, demo);
        }

        final SearchManager searchManager = Search.getSearchManager(cache);
        final QueryBuilder queryBuilder = searchManager.buildQueryBuilderForClass(DemoB.class).get();

        final Query query = queryBuilder.keyword().onField("id").matching(1000l).createQuery();

        final CacheQuery query1 = searchManager.getQuery(query, DemoB.class);

        for (Object  result : query1.list()) {
            System.out.println(result);
        }

    }
}

如您所见，有一个基类DemoA及其子类DemoB。我想按超级类文件id进行搜索。但是，此演示代码会生成org.hibernate.search.SearchException: Unable to find field id in com.genesis.inifispan.InifinispanTest$DemoB

我假设我错过了Search Mapping configuration中的继承配置，但是通过查看文档，我什么也没有找到。我想有基于Java的配置，因为我不能改变生产环境中的实体类。

请，您可以帮助我配置或指导我以正确的方式阅读文档。

在使用SearchMapping时，您应该像处理注释一样指定字段: id是仅用于DemoA的有效字段，因此正确的映射如下所示：

SearchMapping mapping = new SearchMapping()
   .entity(DemoA.class)
      .property("id", ElementType.METHOD).field()
   .entity(DemoB.class).indexed()
   ;

还请注意，我删除了providedId()：在最近的Infinispan版本中不再需要。

我认为SearchMapping至少应该警告你，甚至可以立即抛出一个例外:打开JIRA HSEARCH-1328 。
