lambda表达式----使用

List<THealthKnowledgeEntity> tHealthKnowledgeList = tHealthKnowledgeService.queryList(query);
List<THealthKnowledgeEntity> list=tHealthKnowledgeList.stream().filter(tHealthKnowledgeEntity -> "0".equals(tHealthKnowledgeEntity.getDel()))
      .peek(tHealthKnowledgeEntity->
            tHealthKnowledgeEntity.setImgUrl(ossClientConfig.getOssAddress()+"/"+ossClientConfig.getBucketName()+"/"+ tHealthKnowledgeEntity.getImgUrl())
      ).collect(Collectors.toList());
int total = tHealthKnowledgeService.queryCount(query);

PageUtils pageUtil = new PageUtils(list, total, query.getLimit(), query.getPage());
