package lambda; import java.time.LocalDateTime; import java.time.format.DateTimeFormatter; import java.util.ArrayList; import java.util.List; import org.apache.commons.lang.StringUtils; public class TestTime { public static void main(String[] args) { DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"); LocalDateTime oldEndTime=LocalDateTime.parse("2021-09-04 19:00:00",formatter); System.out.println("oldEndTime===="+oldEndTime); LocalDateTime now=LocalDateTime.now(); System.out.println(now); System.out.println("===="+now.isAfter(oldEndTime)); List<String>list=new ArrayList<>(); String mm=String.format("%s=%s", "zhangsan",123); String nn=String.format("%s=%s", "lisi",123); list.add(mm); list.add(nn); String publicReqStr = StringUtils.join(list, "&"); System.out.println("mmm==="+mm); System.out.println("publicReqStr==="+publicReqStr); } }
