字符串List<String>各种操作
1、打印List<String> 日志,用, 进行分割
String collect = ibds.stream()
.collect(Collectors.joining(","));
测试
List<String> ibds = new ArrayList<String>(); ibds.add("a1"); ibds.add("a2"); ibds.add("a3"); ibds.add("a4"); String collect = ibds.stream() .collect(Collectors.joining(",")); System.out.println("exportSnByIBD param="+collect);
List<String> ibds = new ArrayList<String>(); ibds.add("a1"); ibds.add("a2"); ibds.add("a3"); ibds.add("a4"); String collect = ibds.stream() .collect(Collectors.joining(",")); System.out.println("exportSnByIBD param="+collect);
2、List<String> 去重
List<String> newshipNumbers = ibds.stream().distinct().collect(Collectors.toList());
页面上根据订单号导出,可以输入多个订单号,添加一个判断,就是去重。不然导出的数据有重复的
