使用匿名函数的方式对result数据进行排序：
Collections.sort(result, new Comparator<WorkerVO>() { @Override public int compare(WorkerVO o1, WorkerVO o2) { int serviceCount1 = o1.getServiceCount(); int serviceCount2 = o2.getServiceCount(); long restMinutes1 = o1.getRestMinutes(); long restMinutes2 = o2.getRestMinutes(); if (0 == rankTyepe) {//服务人数降序 int compare = Integer.compare(serviceCount2, serviceCount1); return compare==0?Long.compare(restMinutes1, restMinutes2):compare; } else if (1 == rankTyepe) { //服务人数升序 int compare = Integer.compare(serviceCount1, serviceCount2); return compare==0?Long.compare(restMinutes2, restMinutes1):compare; `//表示，如果服务人数相等就按空闲时间排序（多条件排序的应用和）` } return 0; } });java8:对list排序
list.sort((a, b) -> Integer.compare(a.age, b.getAge())); assignWorkerDOList.sort((a, b) -> Long.compare(a.getServiceStartDate().getTime(), b.getServiceStartDate().getTime()));参考：https://blog.csdn.net/j277699931/article/details/49660607
