概念实操

注解

PHP没有注解，但是可以利用反射来读取类或方法上的注释内容


/**
 * 
 */

控制器


namespace App\Controllers;

use Swoft\Http\Server\Bean\Annotation\Controller;
use Swoft\Http\Server\Bean\Annotation\RequestMapping;
use Swoft\Http\Server\Bean\Annotation\RequestMethod;

/**
 * @Controller(prefix="/users")
 */
class UsersController
{
    /**
     * @RequestMapping(route="/test", method=RequestMethod::POST)
     * @return String
     */
    function test()
    {
        return 'Hello World';
    }
}

实体


# 源码安装执行命令
php bin/swoft entity:create -d test -i user

# docker环境下执行命令
docker exec -it swoft php bin/swoft entity:create -d test -i user
