如何动态添加静态资源到spring-boot jar应用程序？ [英] How to dynamically add static resources to spring-boot jar application?

问题描述

我有spring-boot应用程序，它使用html静态页面创建目录。当我按命令启动应用程序时： mvn spring-boot：run 一切正常（带有静态页面的文件夹在 / resources / 目录和客户端可以访问页面）但我希望我的应用程序部署为jar文件，在这里我有我的问题，我怎样才能实现我的目标？我知道我不能动态地将资源添加到jar，但也许我可以创建包含我的jar文件旁边的资源的文件夹，并以某种方式将此文件夹添加到公共资源，以便客户端可以访问html页面。

I have spring-boot application which creates catalog with html static pages. When I start application by command: mvn spring-boot:run everything works good (folder with static pages is created in /resources/ catalog and client have access to pages) but I want have my app deployed as jar file and here I have my question, how can I achieve my goal? I understand that I can't add dynamically resources to jar but maybe I can create folder with resources next to my jar file and somehow add this folder to public resources so client could have access to html pages.

推荐答案

尝试使用文件：为资源位置添加前缀，例如：

Try prefixing you resource location with file:, for example:

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/external/**")
            .addResourceLocations("file:external/");
}

此路径相对于启动应用程序的目录。您还可以使用绝对路径，例如 file：/ path / to / resources 。

This path is relative to the directory from which you launched the application. You can also use an absolute path, for example file:/path/to/resources.
