### Question:
DictService { public DictDto findDictById(String resId) { return dictDao.findById(resId) .map(dictMapper::toDto) .orElseThrow(ResourceNotFoundException::new); } DictService(DictDao dictDao,
	                   DictMapper dictMapper); Page<DictDto> findDictByCondition(DictDto dictDto, Pageable pageable); List<DictDto> fetchDictTreeList(DictDto dictDto); DictDto findDictById(String resId); void saveOrUpdate(DictDto dictDto); void deleteBatch(List<String> resId); List<DictDto> findIdNameTypeByParentId(DictDto dictDto);  }### Answer:
@Test public void findDictById() { DictDto dictByCondition = dictService.findDictById("1133978689470599168"); System.out.println(dictByCondition); }
