Java 映射异常：无法'；在实现AbstractElasticsearchConfiguration时找不到持久性

我想为我的对象following和answer实现自定义转换器，但是当我运行该项目时，我收到MappingException:找不到类型类TransactionElistic的PersistentEntity

这是我的配置

@Configuration
public class ElasticConfig extends AbstractElasticsearchConfiguration {


    @Value("$elasticUrl")
    private String elasticUrl;

    @Override
    public RestHighLevelClient elasticsearchClient() {
        return RestClients.create(ClientConfiguration.create(elasticUrl)).rest();
    }

    @Bean
    public EntityMapper entityMapper() {
        ElasticsearchEntityMapper entityMapper = new ElasticsearchEntityMapper(elasticsearchMappingContext(), new DefaultConversionService());
        entityMapper.setConversions(elasticsearchCustomConversions());
        return entityMapper;
    }

    @Bean
    @Override
    public ElasticsearchCustomConversions elasticsearchCustomConversions() {
        return new ElasticsearchCustomConversions(Arrays.asList(new TransactionToMapConverter(), new MapToTransactionConverter()));
    }
}

@WritingConverter
public class TransactionToMapConverter implements Converter<TransactionElastic, Map<String, Object>> {
    @Override
    public Map<String, Object> convert(TransactionElastic tradeTransaction) {
        Map<String, Object> target = new HashMap<>();
        target.put("id", tradeTransaction.getId());
        target.put("portfolio_name", tradeTransaction.getPortfolioName());
        target.put("settl_date", tradeTransaction.getSettlDate());
        return target;
    }
}
@ReadingConverter
public class MapToTransactionConverter implements Converter<Map<String, Object>, TransactionElastic> {
    @Override
    public TransactionElastic convert(Map<String, Object> map) {
        TransactionElastic t = new TransactionElastic();
        t.setPortfolioName(map.get("portfolio_name").toString());
        t.setId((Long) map.get("id"));
        return t;
    }
}

@Document(indexName = "transactions")
public class TransactionElastic {
    @Id
    private Long id;
    @Field(name = "portfolio_name", type = FieldType.Text)
    private String portfolioName;
    @Field(name = "settl_date", type = FieldType.Date)
    private Date settlDate;
    @Field(name = "trscn_status", type = FieldType.Text)
    private String trscnStatus;
    // getters and setters here 
}

什么可能导致问题？我遗漏了什么吗？

我认为它无法找到实体。请在

AbstractElasticsearchConfiguration

中扩展以下方法：

@Override
protected Collection<String> getMappingBasePackages() {
    //Provide list of your packages where you have entities.
}

@覆盖
受保护的集合getMappingBasePackages（）{
//提供您拥有实体的软件包列表。
}

你能发布stacktrace吗？嗨@SimonMartinelli，我已经更新了问题，添加了StackTrace您的包结构是什么样子的？com.portal.domain-for@Document objects com.portal.search-elasticsearch repositories com.portal.service-for service interfaces and implementation com.portal.config-with configs com.portal.converter-with convertersAnd，其中包是SpringBootApplication？将我的配置更新为遵循@Override protected Collection getMappingBasePackages（）{return Collections.singletonList（“com.meritkapital.portal.domain”）；}但仍然有相同的例外我还建议尝试创建一个简单的配置bean，而不是扩展AbstractElasticsearchConfiguration，因为它正在禁用一些自动配置。与其扩展它，不如创建一个配置bean，并根据需要创建方法级bean。谢谢您的建议。试图在配置中只保留Elasticsearch CustomConversions方法bean，但没有帮助。

@Override
protected Collection<String> getMappingBasePackages() {
    //Provide list of your packages where you have entities.
}
