</config>
Mastering / Itdesire / registration.php
<?php
\Magento\Framework\Component\ComponentRegistrar::register(

);
2.如何安装和升级数据库：
安装模式：
精通/意念/设置/InstallSchema.php
<?php
/*

* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
/**

*
* @author pramod
*/
namespace Mastering\Itdesire\Setup;
use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\DB\Ddl\Table;
class InstallSchema implements InstallSchemaInterface
{
/**
* {@inheritdoc}
*/
public function install(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
$setup->startSetup();
$table = $setup->getConnection()->newTable(

)->addColumn(
'id',
Table::TYPE_INTEGER,
null,
['identity' => true, 'nullable' => false, 'primary' => true],
'Item ID'
)->addColumn(
'name',
Table::TYPE_TEXT,
255,
['nullable' => false],
'Item Name'
)->addIndex(
$setup->getIdxName('mastering_itdesire_item', ['name']),
['name']
)->setComment(
'itdesire Items'
);
$setup->getConnection()->createTable($table);
$setup->endSetup();
}
}
安装数据：
精通/意念/设置/InstallData.php
<?php
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
$setup->startSetup();
$setup->getConnection()->insert(
$setup->getTable('mastering_itdesire_item'),
[

]
);
$setup->getConnection()->insert(
$setup->getTable('mastering_itdesire_item'),
[
'name' => 'Item 2'
]
);
$setup->endSetup();
}
}
升级架构：
精通/意念/设置/UpgradeSchema.php
<?php
/*

*/
public function upgrade(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
$setup->startSetup();
if (version_compare($context->getVersion(), '1.0.1', '<')) {
$setup->getConnection()->addColumn(

'description',
[
'type' => Table::TYPE_TEXT,
'nullable' => true,

]
);
}
$setup->endSetup();
}
}
