对于spring引导api:

@Configuration
public class JsonConfig {

    @Bean
    public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter();
        ObjectMapper mapper = new ObjectMapper();

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

        mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);// will remove value properties
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        jsonConverter.setObjectMapper(mapper);
        return jsonConverter;
    }
}

导入以下依赖项:

implementation 'com.fasterxml.jackson.core:jackson-core:2.13.0'
implementation 'com.fasterxml.jackson.core:jackson-databind:2.13.0'
implementation 'com.fasterxml.jackson.datatype:jackson-datatype-jsr310:2.13.0'

这个maven依赖将解决你的问题:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.13.4</version>
</dependency>

我一直在挣扎的一件事是，在反序列化期间，ZonedDateTime时区被更改为GMT。 结果，Jackson默认用上下文中的一个替换它。 要保留区域1，必须禁用此“功能”

Jackson2ObjectMapperBuilder.json()
    .featuresToDisable(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE)

我想为Spring的DurationStyle解析提供支持，在使用Jackson反序列化的自定义配置文件中的属性文件中提供支持，例如将20s序列化为Duration PT20S。我通过在ObjectMapper实例上注册一个自定义反序列化器来实现这一点:

@Bean("customConfigMapper")
public ObjectMapper customConfigMapper() {
    final ObjectMapper mapper = new ObjectMapper();
    final SimpleModule module = new SimpleModule();
    module.addDeserializer(Duration.class, new SpringDurationStyleDeserializer());
    mapper.registerModule(module);
    return mapper;
}

public static class SpringDurationStyleDeserializer extends JsonDeserializer<Duration> {
    @Override
    public Duration deserialize(JsonParser jsonParser, DeserializationContext __) throws IOException {
        return Optional.ofNullable(jsonParser.getText()).map(DurationStyle::detectAndParse).orElse(null);
    }
}

我在使用Spring boot时遇到了类似的问题。 使用Spring启动1.5.1。我所要做的就是添加依赖项:

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

如果你考虑使用fastjson，你可以解决你的问题，注意版本

 <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
        <version>1.2.56</version>
 </dependency>

如果你正在使用Jackson Serializer，下面是一种使用date模块的方法:

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jdk8.Jdk8Module;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import com.fasterxml.jackson.module.paramnames.ParameterNamesModule;
import org.apache.kafka.common.serialization.Serializer;

public class JacksonSerializer<T> implements Serializer<T> {

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

    @Override
    public byte[] serialize(String s, T object) {
        try {
            return mapper.writeValueAsBytes(object);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
        return null;
    }
}
