java中SearchFilter有这个类吗

private Specification buildSpecification(Long userId,
Map searchParams) {
Map filters = SearchFilter.parse(searchParams);
filters.put("user.id", new SearchFilter("user.id", Operator.EQ, userId));
Specification

spec = DynamicSpecifications.bySearchFilter(
filters.values(), Task.class);
return spec;
}
