Jackson序列化和反序列化忽略字段操作

  FilterProvider filterProvider = new SimpleFilterProvider();

  SimpleBeanPropertyFilter fieldFilter = SimpleBeanPropertyFilter().serializeAllExcept("name");
  filterProvider.addFilter("fieldFilter");
  new ObjectMapper.setFilters(filterProvider );

public final class JsonFilterUtil {

  /**
   * 添加过滤的字段，这里过滤的是 ThinActivityInfo 这个 bean 下的 
   * "startAt", "expiredAt", "extra" 三个字段
   */
  public static void addFilterForMapper(ObjectMapper mapper) {
    SimpleBeanPropertyFilter fieldFilter = SimpleBeanPropertyFilter.serializeAllExcept(
        Sets.newHashSet("startAt", "expiredAt", "extra"));
    SimpleFilterProvider filterProvider = new SimpleFilterProvider().addFilter("fieldFilter", fieldFilter);
    mapper.setFilterProvider(filterProvider).addMixIn(ThinActivityInfo.class, FieldFilterMixIn.class);
  }

  /**
   * 定义一个类或接口
   */
  @JsonFilter("fieldFilter")
  interface FieldFilterMixIn{
  }
}
