如何解决数据传输时的繁琐问题？使用mark-gerarts/auto-mapper-plus可以！

composer require mark-gerarts/auto-mapper-plus

<?php

use AutoMapperPlus\Configuration\AutoMapperConfig;
use AutoMapperPlus\AutoMapper;

class Employee
{
    private $id;
    private $firstName;
    private $lastName;
    private $birthYear;

    public function __construct($id, $firstName, $lastName, $birthYear)
    {
        $this->id = $id;
        $this->firstName = $firstName;
        $this->lastName = $lastName;
        $this->birthYear = $birthYear;
    }

    public function getId()
    {
        return $this->id;
    }

    // 其他 getters 省略...
}

class EmployeeDto
{
    public $firstName;
    public $lastName;
    public $age;
}

$config = new AutoMapperConfig();

$config
    ->registerMapping(Employee::class, EmployeeDto::class)
    ->forMember('age', function (Employee $source) {
        return date('Y') - $source->getBirthYear();
    })
    ->reverseMap();

$mapper = new AutoMapper($config);

$john = new Employee(10, "John", "Doe", 1980);
$dto = $mapper->map($john, EmployeeDto::class);

echo $dto->firstName; // 输出 "John"
echo $dto->lastName; // 输出 "Doe"
echo $dto->age; // 输出 43
