存储在Elastic中的员工的生日似乎存储为不正确的数据类型。我为Elasticseach客户端设置了对象Map器和注册的JavaTime模块的代码。我尝试从Elasticsearch中提取员工列表，但似乎不起作用，反序列化失败。

您的问题可能是因为Jackson不支持Java 8 DateTime API，所以您可以添加以下库来添加对它的支持（在pom.xml中添加）：

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.4.0</version>
</dependency>

并配置对象Map器以使用此库模块，如下所示：

ObjectMapper mapper = new ObjectMapper()
   .registerModule(new ParameterNamesModule())
   .registerModule(new Jdk8Module())
   .registerModule(new JavaTimeModule());

我已经成功地在Spring Data Elasticsearch中使用了java.time类型，配置如下：

@Configuration
@EnableElasticsearchRepositories(basePackages = "org.example.search.repository")
public class ElasticsearchConfig {

    @Bean
    public ElasticsearchTemplate elasticsearchTemplate(Client client) {
        return new ElasticsearchTemplate(client, new CustomEntityMapper());
    }

    static class CustomEntityMapper implements EntityMapper {

        private final ObjectMapper mapper;

        CustomEntityMapper() {
            mapper = new ObjectMapper()
                    .setDefaultPropertyInclusion(Include.NON_NULL)
                    .disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)
                    .disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
                    .enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY)
                    .findAndRegisterModules();
        }

        @Override
        public String mapToString(Object object) throws IOException {
            return mapper.writeValueAsString(object);
        }

        @Override
        public <T> T mapToObject(String source, Class<T> clazz) throws IOException {
            return mapper.readValue(source, clazz);
        }
    }
}

这更像是一种解决方法，但可以在相应的localdate/localdatetime字段上添加下面提到的注解。

@JsonDeserialize(using = LocalDateTimeDeserializer.class)
@JsonSerialize(using = LocalDateTimeSerializer.class)

对于正在寻找版本ES-8和Sping Boot ：3.0上的解决方案的用户
创建一个扩展ElasticsearchConfiguration的配置类，并覆盖clientConfiguration和elasticsearchClient创建。
在elasticsearchClient创建过程中，注入配置为使用Java 8时间模块的您自己的objectMapper，这将覆盖默认的objectMapper。

@Override
public ClientConfiguration clientConfiguration() {
    return ClientConfiguration.builder()
            .connectedTo(<Hostname> +":"+ <Port>)
            .usingSsl()
            .withBasicAuth(<Username>, <Password>)
            .build();
}

@Override
public ElasticsearchClient elasticsearchClient(RestClient restClient) {
    Assert.notNull(restClient, "restClient must not be null");

    //Create Java8 time module
    JavaTimeModule module = new JavaTimeModule();
    module.addSerializer(new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DateFormat.date_time_no_millis.getPattern())));

    //Register the module with objectMapper
    ObjectMapper objectMapper=new ObjectMapper()
            .registerModule(module);

    //To convert datetime to ISO-8601
    objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

    //Creating our own jsonpMapper 
    JsonpMapper jsonpMapper=new JacksonJsonpMapper(objectMapper);

    // Create the transport with a Jackson mapper
    ElasticsearchTransport transport = new RestClientTransport(
            restClient, jsonpMapper);

    // And create the API client
    return  new ElasticsearchClient(transport);
}

Maven依赖项：

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.14.0</version>
</dependency>
