com.anwen.mongo.mapper.DefaultBaseMapperImpl的update，文档没有修改会返回更新失败，应该再加一个判断更严谨

    @Override
    public Long update(Bson queryBasic, Bson updateBasic, Class<?> clazz) {
        UpdateResult result  = factory.getExecute().executeUpdate(
                queryBasic,
                updateBasic,
                `mongoPlusClient.getCollection(clazz)`
        );
      return result.getModifiedCount()==0 && result.getMatchedCount() == 0;
    }
