You can get the configuration values in following ways-

\Magento\Framework\App\Config\ScopeConfigInterface class is used in constructor argument to get the configuration values simply as below-

Magento 2 get system config value Example:

<?php


namespace Tutorialsplane\HelloWorld\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action
{

    protected $resultPageFactory;

    /**
     * Constructor
     *
     * @param \Magento\Framework\App\Action\Context  $context
     * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
     */
    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory,
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    ) {
        $this->resultPageFactory = $resultPageFactory;        
        $this->_scopeConfig = $scopeConfig;
        parent::__construct($context);
    }

    /**
     * Execute view action
     *
     * @return \Magento\Framework\Controller\ResultInterface
     */
    public function execute()
    {
        return $this->resultPageFactory->create();
    }

    public function getConfigValue(){
       $myconfig = $this->_scopeConfig->getValue('section/group/field', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);
    }
}
?>

In the above example we have created method – getConfigValue() to get the configuration value where you need to pass the section, group, field id and store scope. You can use the same method to get the configuration in Model, Blocks and Helpers as well.
