joda time获取当前日期和昨天的日期 (格式yyyy-MM-dd)以及获取具体年、月、日

@Test
 public void testJodaTime(){
     LocalDate localDate = new LocalDate();
     System.out.println(localDate.toString());//获取当前日期  2022-06-23
     LocalDate yesterday = localDate.plusDays(-1);// 往前推一天，得到昨天的日期
     System.out.println(yesterday.toString());// 2022-06-22
 }

@Test
    public void testJodaTime(){
        DateTime dateTime = new DateTime();
        int day = dateTime.getDayOfMonth();
        int month = dateTime.getMonthOfYear();
        int year = dateTime.getYear();
        System.out.println("今天是"+ day +"号");
        System.out.println("现在是"+ month +"月");
        System.out.println("现在是"+ year +"年");
    }
