东八区springboot如何配置序列化

spring:
  jackson:
    time-zone: GMT+8

@Configuration
public class JacksonConfiguration {

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> builder.timeZone(TimeZone.getTimeZone("GMT+8"));
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;

public class CustomObjectMapper extends ObjectMapper {
    public CustomObjectMapper() {
        JavaTimeModule javaTimeModule = new JavaTimeModule();
        javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ISO_LOCAL_DATE_TIME));
        javaTimeModule.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ISO_LOCAL_DATE_TIME));
        this.registerModule(javaTimeModule);
        this.setTimeZone(TimeZone.getTimeZone("Asia/Shanghai"));
    }
}

CustomObjectMapper objectMapper = new CustomObjectMapper();
String jsonString = objectMapper.writeValueAsString(yourObject);
YourObject deserializedObject = objectMapper.readValue(jsonString, YourObject.class);

@Configuration
public class JacksonConfig {

    @Bean
    public ObjectMapper objectMapper() {
        return new CustomObjectMapper();
    }
}

public class ChinaZoneDateTimeSerializer extends JsonSerializer<ZonedDateTime> {

    @Override
    public void serialize(ZonedDateTime value, JsonGenerator gen, SerializerProvider serializers) throws IOException {
        gen.writeString(value.withZoneSameInstant(ZoneId.of("GMT+8")).format(DateTimeFormatter.ISO_OFFSET_DATE_TIME));
    }
}

@JsonSerialize(using = ChinaZoneDateTimeSerializer.class)
private ZonedDateTime createTime;
