java8 新特性 DateTimeFormatter

/**
         * 1 新日期处理函数 DateTimeFormatter 是线程安全的
         * SimpleTimeFormatter 线程是不安全的，可以使用枷锁或者使用ThradLocal来实现  比较复杂
         */
        LocalDateTime nowTime = LocalDateTime.now();
        nowTime.plusDays(1);
        System.out.println(nowTime.plusDays(-1).format(formatter));
        System.out.println(11);
        System.out.println(format(new Date()));
    }

    private static ThreadLocal<DateFormat> threadLocal = new ThreadLocal<DateFormat>() {
        @Override
        protected DateFormat initialValue() {
            return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        }
    };

    /**
     * 　　 @Description: 返回本线程值

     * 　　 @date  @DATE@TIME
     *      @return ${return_type}
