我正在尝试在this tutorial之后在Spring Boot应用程序中设置Hibernate Search。问题是我在启动时遇到错误:

我不明白是什么原因导致了这个问题。
相关代码:
@SpringBootApplication
@EnableJpaRepositories(basePackages = "mz.api.spring.repository")
@EntityScan(basePackages = "mz.api.hibernate.model")
@EnableTransactionManagement
public class Application {
private final static Logger LOGGER = LogManager.getLogger(Application.class);
public static void main(String[] args) {
LOGGER.debug("Running application ..");
SpringApplication.run(Application.class, args);
}
}
..
@Service
public class HibernateSearchService {
private final EntityManager entityManager;
@Autowired
public HibernateSearchService(EntityManager entityManager) {
this.entityManager = entityManager;
}
public void initializeHibernateSearch() {
try {
FullTextEntityManager fullTextEntityManager = getFullTextEntityManager(this.entityManager);
fullTextEntityManager.createIndexer().startAndWait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
..
@Configuration
public class HibernateSearchConfig {
private final EntityManager entityManager;
@Autowired
public HibernateSearchConfig(EntityManager entityManager) {
this.entityManager = entityManager;
}
@Bean
HibernateSearchService hibernateSearchService() {
HibernateSearchService hibernateSearchService = new HibernateSearchService(this.entityManager);
hibernateSearchService.initializeHibernateSearch();
return hibernateSearchService;
}
}
最佳答案
我设法通过 Autowiring EntityManagerFactory使其工作。然后使用EntityManagerFactory创建一个EntityManager。
@Service
public class HibernateSearchService {
private final EntityManager entityManager;
@Autowired
public HibernateSearchService(final EntityManagerFactory entityManagerFactory) {
this.entityManager = entityManagerFactory.createEntityManager();
}
@PostConstruct
public void initializeHibernateSearch() {
try {
FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(entityManager);
fullTextEntityManager.createIndexer().startAndWait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
