创建初始索引时 Hibernate Search 失败

Question

我正在尝试将 Hibernate Search 集成到 Spring Boot 2 应用程序中。我已经按照其网站上的兼容性列表尝试了不同的版本，但当应用程序启动和“fullTextEntityManager.createIndexer().startAndWait();”时我总是收到此错误 被执行：

线程“main”中的异常 java.lang.IllegalArgumentException：HSEARCH000349：某些指定的实体类型（“class java.lang.Object”）未建立索引，它们的任何子类也未建立索引。

经过三天的谷歌搜索和尝试了很多事情之后，我不知道我还能做什么。

由于数据源配置是由 spring boot 处理的，因此我没有 persistence.xml 文件，因此我将 Hibernate Search 属性放在 application.properties 中。实际上，我也将这些属性放入 hibernate.properties 中，试图使其工作。

应用程序属性

...
spring.datasource.username=*******
spring.datasource.password=*******
spring.jpa.database=MYSQL
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.hibernate.ddl-auto=none
spring.jpa.show-sql=false
spring.jpa.hibernate.naming.physicalstrategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.hibernate.search.default.directory_provider=filesystem
spring.jpa.hibernate.search.default.indexBase=/lucene/indexes

休眠属性

hibernate.search.default.directory_provider=filesystem
hibernate.search.default.indexBase=/lucene/indexes

我的实体餐厅要编入索引：

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
@EqualsAndHashCode
@Indexed
@Spatial
@Entity
@Table(name = "restaurant")
public class Restaurant {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @Field(index = Index.YES, analyze = Analyze.NO, store = Store.YES)
    private String name;
    private String address;
    @Latitude
    private Double latitude;
    @Longitude
    private Double longitude;
}

我在 Spring Boot 启动后初始化 Hibernate Search

@SpringBootApplication
public class PlacesApplication {

    public static void main(String[] args) {
        ConfigurableApplicationContext context = 
        SpringApplication.run(PlacesApplication.class, args);

        context.getBean(HibernateSearchService.class)
        .initializeHibernateSearch();
}

我的 Hibernate 搜索服务如下所示：

@AllArgsConstructor
@Service
@Slf4j
public class HibernateSearchService {

    private EntityManager entityManager;
    @Transactional
    public void initializeHibernateSearch() {

        try {
            FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(entityManager);
            fullTextEntityManager.createIndexer().startAndWait();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

我发现了这个问题，非常非常愚蠢的问题......

我的 IDE 刚刚导入了错误的 Indexed 注释 它设置了 import org.springframework.stereotype.Indexed; 而不是导入 org.hibernate.search.annotations.Indexed;
