springboot序列化record问题

新建一个RecordJackSonSerializer

public class RecordJackSonSerializer extends JsonSerializer<Record> {

	@Override
	public void serialize(Record record, JsonGenerator gen, SerializerProvider serializers) throws IOException {
		gen.writeObject(record.getColumns());
	}
}

然后再配置该类

@Configuration
public class JacksonConfiguration {

    /**
     * Support for Java date and time API.
     * @return the corresponding Jackson module.
     */
    @Bean
    public JavaTimeModule javaTimeModule() {
        return new JavaTimeModule();
    }

    @Bean
    public Jdk8Module jdk8TimeModule() {
        return new Jdk8Module();
    }
    
    @Bean
    @Primary
    @ConditionalOnMissingBean(ObjectMapper.class)
    public ObjectMapper jacksonObjectMapper(Jackson2ObjectMapperBuilder builder) {
        ObjectMapper objectMapper = builder.createXmlMapper(false).build();
        SimpleModule simpleModule = new SimpleModule();
        simpleModule.addSerializer(Record.class,new RecordJackSonSerializer());
        objectMapper.registerModule(simpleModule);
        
        objectMapper.getSerializerProvider().setNullValueSerializer(new JsonSerializer<Object>() {
            @Override
            public void serialize(Object o, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException, JsonProcessingException {
                jsonGenerator.writeString("");
            }
        });
        return objectMapper;
    }


    /*
     * Jackson Afterburner module to speed up serialization/deserialization.
     */
    @Bean
    public AfterburnerModule afterburnerModule() {
        return new AfterburnerModule();
    }

    /*
     * Module for serialization/deserialization of RFC7807 Problem.
     */
    @Bean
    ProblemModule problemModule() {
        return new ProblemModule();
    }

    /*
     * Module for serialization/deserialization of ConstraintViolationProblem.
     */
    @Bean
    ConstraintViolationProblemModule constraintViolationProblemModule() {
        return new ConstraintViolationProblemModule();
    }

}
