Composer类映射自动加载不会在文件夹中加载新文件 [英] Composer classmap autoload does not load new files in folder

问题描述

以下问题：我在我的composer.json中定义了一个类映射：

The following problem: I have defined a classmap in my composer.json:

"autoload": {
    "classmap": [
        "app/controllers",
        "app/models",
        "app/helper.php"
    ]   
}

但是，当我在controllers或models文件夹中创建一个新文件时，我总是要做一个作曲家dump-autoload。

However, when I create a new file in the "controllers" or "models" folder, it will not load them and I always have to make a composer dump-autoload.

这是正确的行为吗？我认为来自作曲家的自动加载器监视文件夹中的新文件然后？

Is this the correct behavior? I thought the autoloader from composer monitors the folder for new files then?

推荐答案

是的，这是正确的行为。如果你想要自动加载新类，你必须使用PSR-0或PSR-4自动加载。

Yes, this is correct behaviour. If you want new classes to be loaded automatically, you have to use either PSR-0 or PSR-4 autoloading.

生成类映射需要Composer知道包含的文件名一个类。这只能通过解析目录中的所有源代码并扫描类，接口和trait定义来完成。

Generating the classmap requires Composer to know the filename that contains a certain class. This can only be done by parsing the whole source code in the directory and scanning for classes, interfaces and trait definitions.

这通常是一个CPU和I / O密集型任务，因此只有在Composer安装/更新或（按需）转储自动加载器时才会执行，而不是每个 requirevendor / autoload.php;

This usually is a CPU and I/O intensive task, so it is only done when Composer does install/update or (on demand) dumps the autoloader, it is not done with every require "vendor/autoload.php";.

请注意，类映射自动加载仅适用于未实现至少PSR-0的旧旧代码库。它不是为新的代码 - 除非你想支付的价格，在开发过程中一次又一次地转储自动装载机。

Note that the classmap autoloading is simply there for old legacy codebases that didn't implement at least PSR-0. It is not intended for new code - unless you want to pay the price to dump the autoloader again and again during development.
