PSR4不起作用

Question

我已经为一包旧类设置了这样的文件夹结构

vendorname/legacy/src/ClassA.php
namespace VendornameLegacy;
class ClassA{}
vendorname/legacy/src/Folder/Class2.php
namespace VendornameLegacyFolder;
class FolderClass2{}

与作曲家一起，我正在从类似的github存储库中加载它：

"repositories": [
    {
        "type": "vcs",
        "url": "[e-mail]:username/vendorname-legacy-classes.git"
    }
],
"require": {
    "vendorname/legacy": "master@dev"
}

当我这样加载这样的课程时，它有效：

use VendornameLegacyClassA;
$a = new ClassA();

但是，我的子文件夹中都没有工作：

use VendornameLegacyFolderFolderClassB;
$b = new FolderClassB();

Class 'Vendorname\Legacy\Folder\FolderClassB' not found

我已经用文件供应商 vendorname composer.json

定义了源文件夹

{
    "name": "vendorname/legacy",
    "description": "Vendorname Legacy classes",
    "require": {
        "php": ">=5.3.0"
    },
    "autoload": {
        "psr-4": {
            "Vendorname\Legacy\": "src"
        }
    },
    "extra": {
        "branch-alias": {
            "master": "master"
        }
    }
}

您需要为Composer.json

定义一件事

{
    "autoload": {
        "psr-4": {"Vendorname\Legacy\": "vendorname/legacy/src/"}
    }
}
