我@Data在POJO类中使用了注释,但是没有生成getter和setter.我使用的IDE是sts(Spring Tool Suite)

//User POJO Class
import lombok.Data;

@Data
public class UserVo {

    private String name;
    private String userName;
    private String email;
    private String mobile;
    private String password;
}

我正在使用哈希表实现perl fib:

#!/usr/bin/perl

use strict;
use warnings;
no warnings 'recursion';

my %m_fib = (0,1,1,1);

while (my $a = <STDIN>) {
    print "--".&fib($a)."\n";
}

sub fib {
    foreach my $i (@_) {
        if (not defined $m_fib{$i}) {
            $m_fib{$i} = &fib($i - 1) + &fib($i - 2);
        }
        return $m_fib{$i};
    }
}

输入大于1时效果很好,但默认为0或1.

哈希应该没问题,因为它返回了正确的结果,但是如果我用0或1提供它,为什么它不起作用？
