Application.cfc vs Application.cfm 在不同的文件夹中具有更高的优先级

Question

在我的应用程序根文件夹中，我有一个 Application.cfc 文件。在子文件夹中，有一个 Application.cfm。当我在应用程序文件执行的子文件夹中调用脚本时：Application.cfc 或 Application.cfm?

Answer 1

当您调用子文件夹中的模板时，子文件夹中的 Application.cfm 将被执行。

Answer 2

Application.cfm 被执行并了解有关执行顺序的更多信息。 From the documentation:

ColdFusion 如何查找和处理应用程序定义页面

ColdFusion uses the following rules to locate and process the Application.cfc, Application.cfm, and OnRequestEnd.cfm pages that define application-specific elements. The way ColdFusion locates these files helps determine how you structure an application.

Each time ColdFusion processes a page request it does the following:

1. When ColdFusion starts processing the request, it does the following:

   • It searches the page's directory for a file named Application.cfc. If one exists, it creates a new instance of the CFC, processes the initial events, and stops searching. (ColdFusion creates a new
     instance of the CFC and processes its initialization code for each
     request.)

   • If the requested page's directory does not have an Application.cfc file, it checks the directory for an Application.cfm file. If one
     exists, ColdFusion logically includes the Application.cfm page at the beginning of the requested page and stops searching further.

   • If the requested page's directory does not have an Application.cfc or Application.cfm file, ColdFusion searches up the directory tree and checks each directory first for an Application.cfc file and then, if one is not found, for an Application.cfm page, until it reaches the root directory (such as C:). When it finds an Application.cfc or Application.cfm file, it processes the page and stops searching.

2. ColdFusion processes the requested page's contents.
3. When the request ends, ColdFusion does the following:
   • If you have an Application.cfc, ColdFusion processes the CFC's onRequestEnd method and releases the CFC instance.
   • If you do not have an Application.cfc, but do have an Application.cfm page, ColdFusion looks for an OnRequestEnd.cfm in the same directory as the Application.cfm page ColdFusion uses for the current page. ColdFusion does not search beyond that directory, so it does not run an OnRequestEnd.cfm page that resides in another directory. Also, the OnRequestEnd.cfm page does not run if there is an error or an exception on the application page, or if the application page executes the cfabort or cfexit tag.

The following rules determine how ColdFusion processes application pages and settings:

• ColdFusion processes only one Application.cfc or Application.cfm page for each request. If a ColdFusion page has a cfinclude tag pointing to an additional ColdFusion page, ColdFusion does not search for an Application.cfc or Application.cfm page when it includes the additional page.

• If a ColdFusion page has a cfapplication tag, it first processes any Application.cfc or Application.cfm, and then processes the
  cfapplication tag. The tag overrides the settings from the
  application files, including the application name and the behaviors
  set by the cfapplication tag attributes.

• You can have multiple Application.cfc files, Application.cfm files, and cfapplication tags that use the same application name. In this
  case, all pages that have the same name share the same application
  settings and Application scope and set and get all the variables in
  this scope. ColdFusion uses the parameter settings of the
  cfapplication tag or the most recently processed file, if the
  settings, such as the session time-out, differ among the files.

Application.cfc/Application.cfm lookup order

Select the order in which ColdFusion searches for Application.cfm or >Application.cfc if it is not found in the current project folder. You can >set ColdFusion to search as follows:

• default search order: ColdFusion looks for an >Application.cfc/Application.cfm file from the current folder until the >system root directory. On Windows, this could be C:\ and on UNIX, /opt.
• till web root: ColdFusion looks for an Application.cfc/Application.cfm >file from the current folder till web root.
• in web root: ColdFusion looks for an Application.cfc/Application.cfm file >in the current folder or web root.
