  number类型js精度丢失，后端把long类型的字段转成字符串

  仅

  @JsonSerialize(using = ToStringSerializer.class)

  无法解决所有问题

  需要

  PlanckConfiguration {
     ()
     Jackson2ObjectMapperBuilderCustomizer () {
        Jackson2ObjectMapperBuilderCustomizer customizer = Jackson2ObjectMapperBuilderCustomizer() {
           (Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {
              jacksonObjectMapperBuilder.serializerByType(Long.ToStringSerializer.)
                 .serializerByType(Long.ToStringSerializer.)}
        }customizer}
  }

  支持对所有含Long型数据进行全局过滤, 包括HashMap<xx, Long>, LinkedList<Long> ...

  public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
     // 自定义大数字序列化
     builder.serializerByType(Long.TYPE, ToStringSerializer.instance);
     builder.serializerByType(Long.class, ToStringSerializer.instance);
     builder.serializerByType(BigInteger.class, ToStringSerializer.instance);
     builder.serializerByType(BigDecimal.class, ToStringSerializer.instance);

  API加密要使用全局ObjectMapper，且需要定义Jackson2ObjectMapperBuilderCustomizer

  @Bean
  Jackson2ObjectMapperBuilderCustomizer () {
      builder -> builder.serializerByType(Long., ToStringSerializer.)
         .serializerByType(Long., ToStringSerializer.)
         .serializerByType(BigInteger., ToStringSerializer.)
         .serializerByType(BigDecimal., ToStringSerializer.);
  }
