mvc - When learning thinkPHP and using the D method, why is Common/Model called instead of Home/Model? Where is it set?

Learn thinkPHP and use D method, why call Common/Model instead of Home/Model?

Externally called function:

<code>namespace Home\Controller;
use Think\Controller;

public function model_D()
{
    $stmt=D('shop');
    $stmt->say();
}</code>

Two types of files:

<code>被调用的是这个:
C:\AppServ\www\yb1\yangbins\Common\Model\shopModel.class.php
<?php
namespace Common\Model;
use Think\Model;

class shopModel extends Model
{
    function say()
    {
        echo 'i am in namespace Common\Model <br>()';
    }
}
</code>

<code>为什么不是这个?
C:\AppServ\www\yb1\yangbins\Home\Model\shopModel.class.php
<?php
namespace Home\Model;
use Think\Model;

class shopModel extends Model
{
    function say()
    {
        echo 'i am in namespace Home\Model <br>';
    }
}</code>

Using the D method, the class will not be found according to the path specified by the namespace.
D method is to load the first found Class according to priority, and the order starts from comon.

There are two ways to solve your problem.

<code>$model = D("Home/Shop");</code>

Use command space

<code>use Home\Model\shopModel;
$model = new shopModel();</code>

Shouldn’t external calls specify use HomeModelshop?
