Long统一转为String

@Configuration
public class JacksonConfig {

    /**
     * Jackson全局转化long类型为String，解决jackson序列化时long类型缺失精度问题
     * @return Jackson2ObjectMapperBuilderCustomizer 注入的对象
     */
    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return jacksonObjectMapperBuilder -> {
            jacksonObjectMapperBuilder.serializerByType(Long.TYPE, ToStringSerializer.instance);
            jacksonObjectMapperBuilder.serializerByType(Long.class, ToStringSerializer.instance);
        };

    }
