Spring：为类路径资源注入URL [英] Spring: Inject URL for classpath resource

问题描述

我想以一种不会在Bean中创建对Spring的依赖的方式注入类路径资源的URL。意思是，bean不应该使用Spring的接口/类。我怎么能这样做？

I want to inject the URL of a classpath resource in a way that does not create a dependency on Spring in the Bean. Meaning, the bean should not use Spring's interfaces/classes. How can I do that?

推荐答案

Spring能够转换 classpath：... 值隐含地进入 java.net.URL ：

Spring is able to convert classpath:... values into java.net.URL implicitly:

public class Foo {
    private URL url;
    ...
}

。

<bean class = "Foo">
    <property name = "url" value = "classpath:..." />
</bean>
