### Question:
BaseRouterInfoService extends BaseService<BaseRouterInfoMapper, BaseRouterInfo> { public List<RouterInfoVO> getRouterInfoVOByRouterIds(List<String> routerIds) { log.debug("***weiming专用log***查询用户的菜单路由集合【{}】***start***", routerIds); List<RouterInfoVO> emptyList = new ArrayList<>(); routerIds.parallelStream().forEachOrdered(r -> { getRouter(r, emptyList); }); log.debug("***weiming专用log***查询用户的菜单路由集合【{}】***success***", routerIds); return emptyList; }  List<RouterInfoVO> getRouterInfoVOByRouterIds(List<String> routerIds); @SuppressWarnings("unchecked") ObjectRestResponse<List<BaseRouterInfo>> parents(); TableResultResponse<BaseRouterInfo> children(Query query);  }### Answer:
@Test public void test() { String routerIds = "1:3,4&2:5"; List<String> list = StrUtil.split(routerIds, CharUtil.AMP); List<RouterInfoVO> list2 = routerInfoService.getRouterInfoVOByRouterIds(list ); list2.forEach(i -> i.toString()); }
