java8 List一行代码解决重复数据

1、List包含的对象去重：vehicleArchivesBeans.stream().distinct().collect(Collectors.toList());

2、Lis根据某一属性值去重：

List<VehicleArchivesBean> archivesBeans = vehicleArchivesBeans.stream().collect( Collectors.collectingAndThen( Collectors.toCollection(() -> new TreeSet<>(Comparator.comparing(VehicleArchivesBean::getVin))), ArrayList::new) );
