使用转换器将对象作为spring-data-solr文档中的属性

标签： java solr solrj spring-data-solr

我使用spring-data-solr索引我的实体。据我了解，Solrj可以处理Date属性，但无法处理LocalDate。

我尝试在this之后创建并注册自定义转换器，以便在LocalDate和String之间进行转换，但它不起作用。此外，当我尝试使用org.joda.time.LocalDate或org.springframework.data.geo.Point时，我发现即使org.springframework.data.solr.core.convert.SolrCustomConversions中指定的转换器也无效。

从错误响应中，应用程序似乎尝试访问名为 localdate 的核心。

依赖关系：

org.springframework.boot:1.5.3.RELEASE
org.springframework.data:spring-data-solr:2.1.3.RELEASE
org.apache.solr:solr-solrj:6.0.1

代码：

@Getter
@Setter
@SolrDocument(solrCoreName = "testentity")
public class SoTestEntity {

    @Field
    @Indexed
    private String id;

    @Field
    @Indexed(type = "daterange")
    private LocalDate localDateAttribute;
}

public final class TemporalConverters {
    @ReadingConverter
    public enum StringToLocalDateConverter implements Converter<String, LocalDate> {
        INSTANCE;

        @Override
        public LocalDate convert(String source) {
            return StringToLocalDateTimeConverter.INSTANCE.convert(source).toLocalDate();
        }
    }
    @WritingConverter
    public enum LocalDateToStringConverter implements Converter<LocalDate, String> {
        INSTANCE;

        @Override
        public String convert(LocalDate source) {
            if (source == null) {
                return null;
            }
            return source.format(DateTimeFormatter.ISO_DATE);
        }
    }
}

public class SoTest {
    private SolrTemplate template;

    @Before
    public void setUp() throws Exception {
    HttpSolrClient client = new HttpSolrClient("http://localhost:8983/solr");
    template = new SolrTemplate(client);
template.setSchemaCreationFeatures(Collections.singletonList(SolrPersistentEntitySchemaCreator.Feature.CREATE_MISSING_FIELDS));
    MappingContext mappingContext = new SimpleSolrMappingContext();
    MappingSolrConverter converter = new MappingSolrConverter(mappingContext);
    List<Converter> converters = new ArrayList<>();
    converters.add(TemporalConverters.LocalDateTimeToStringConverter.INSTANCE);
    converters.add(TemporalConverters.StringToLocalDateConverter.INSTANCE);
    converter.setCustomConversions(new CustomConversions(converters));
    template.setSolrConverter(converter);
    template.afterPropertiesSet();

    }

    @Test
    public void saveSingleTest() {
        template.saveBean(new SolrTestEntity());
    }
}
