Spring：在上下文根之外提供静态资源

发布于 2024-10-27 09:21:26 字数 437 浏览 1 评论 0原文

在网络应用程序中，我需要提供位于应用程序上下文目录之外的静态内容（图像）。整个应用程序架构要求我使用 Tomcat 来执行此操作。我认为我可以受益于 Spring 的来配置应用程序 URL 和目录内容之间的映射。但据我所知，它的 mapping 属性仅处理上下文相关或类路径映射。因此，我想使用的 :

<mvc:resources location="/images/**" mapping="/absolute/path/to/image/dir"/>

不起作用。因为我宁愿避免编写一个简单的文件传输 servlet，所以如果有人能给我一些关于现有的基于 Spring 的解决方案/解决方法的指示，我会很高兴。

非常感谢。

原文

in a web app, I need to serve static contents (images) located outside the application context directory. The overall application architecture requires me to use Tomcat to perform this. I thought I could benefit from Spring's <mvc:resources> to configure a mapping between application URLs and directory contents. But AFAIK it's mapping attribute only handles context relative, or classpath mappings. Hence, what I'd like to use :

<mvc:resources location="/images/**" mapping="/absolute/path/to/image/dir"/>

doesn't work. As I'd rather avoid writing a simple file transfer servlet, I'd be glad if anyone could give me some pointers on existing Spring based solutions/workarounds.

Many thanks.

可以从外部提供资源，需要使用常用的Spring 资源路径语法：

<mvc:resources mapping="/images/**" location="file:/absolute/path/to/image/dir/"/>

<mvc:resources> can serve resources from the outside, you need to use the usual Spring resource path syntax:

<mvc:resources mapping="/images/**" location="file:/absolute/path/to/image/dir/"/>

还有一个更简单的更正，

代码应该是

你注意到差异了吗？
您需要将“/”放在绝对路径的末尾。

或者你可以使用java配置

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    String rootPath = System.getProperty("user.home");
    String imagePath = "file:"+rootPath + File.separator + "tmpFiles/";
    System.out.println(imagePath);
    registry.addResourceHandler("/resources/**").addResourceLocations("resources/");
    registry.addResourceHandler("/tmpFiles/**").addResourceLocations(imagePath);
}

它对我有用。

There is one more simple correction

the code should be

<mvc:resources mapping="/images/**" location="file:/absolute/path/to/image/dir/"/>

Did you notice the difference ?
You need to put '/' at the end of the absolute path.

or you can use the java configuration

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    String rootPath = System.getProperty("user.home");
    String imagePath = "file:"+rootPath + File.separator + "tmpFiles/";
    System.out.println(imagePath);
    registry.addResourceHandler("/resources/**").addResourceLocations("resources/");
    registry.addResourceHandler("/tmpFiles/**").addResourceLocations(imagePath);
}

Its working for me.
