我知道有一些问题与我的问题重复，但没有一个问题解决了我的问题，因此我创建了一个新问题。
我有一个带有JDK17的spring Boot 应用程序（v 2.7.6），它查询一个ElasticSearch对象。该对象包含一个Instant字段，当Map到Java对象时，该字段会导致以下错误：

2022-12-07 00:43:14.442 ERROR 59384 --- [nio-8080-exec-2] o.a.c.c.C.[.[.[.[dispatcherServlet]      : Servlet.service() for servlet [dispatcherServlet] in context with path [/api/v1] threw exception [Request processing failed; nested exception is co.elastic.clients.json.JsonpMappingException: Error deserializing co.elastic.clients.elasticsearch.core.GetResponse: jakarta.json.JsonException: Jackson exception (JSON path: _source) (line no=1, column no=280, offset=-1)] with root cause

最初我没有Jackson配置，所以我会认为默认的Jackson将刚刚工作。
在阅读其他stackoverflow的帖子之后，我尝试创建一个这样的配置类，但它并没有解决这个问题：

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import org.openapitools.jackson.nullable.JsonNullableModule;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.annotation.PostConstruct;

@Configuration
public class JacksonConfiguration {

    private final ObjectMapper objectMapper;

    public JacksonConfiguration(ObjectMapper objectMapper) {
        this.objectMapper = objectMapper;
    }

    @Bean
    public JavaTimeModule dateTimeModule(){
        return new JavaTimeModule();
    }

    @PostConstruct
    ObjectMapper jacksonObjectMapper() {
        objectMapper.registerModule(new JavaTimeModule());
        objectMapper.registerModule(new JsonNullableModule());
        return objectMapper;
    }
}

以下也是我的依赖：

两件事，添加错误日志中提到的依赖项（我看到你已经这样做了），然后在你的spring配置中创建一个objectmapper bean供你的服务使用。请删除上面config类中的内容，并将其简化为以下一个bean方法：

@Bean
ObjectMapper jacksonObjectMapper() {
    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.registerModule(new JavaTimeModule());
    return objectMapper;
}
