Java 如何通过SpringMVC4以编程方式将外部视频/图像目录加载到我的网页上？

到目前为止，我可以按如下方式配置我的资源，即我的css和js：

@Configuration
@EnableWebMvc
@ComponentScan("com.xx.xx.xxx")
public class WebAppConfig extends WebMvcConfigurerAdapter{

// Maps resources path to webapp/resources
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");   
}

...

我可以在jsp端加载，如下所示：

<link href="<c:url value="../resources/css/mymaincss.css" />" rel="stylesheet">

我真正想做的是

在我的视频标签上，在开始视频之前和视频开始时显示视频的缩略图

 <video width="560" height="340" controls>
    <img src="/home/myHomedir/thumbnailLocation/to/myvideo.jpg" />
    <source src="/home/myHomedir/videoLocationPath/to/myvideo.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
    <source src="/home/myHomedir/videoLocationPath//myvideo.ogv" type='video/ogg; codecs="theora, vorbis"'>
    </video>

如何在SpringMVC4中以编程方式配置spring以读取外部目录/home/myHomedir/videoLocationPath/以及视频名称

请留下代码的例子，如果它是一个太多的干扰

提前感谢您。

在SpringMVC中，位置中的前缀指示查找策略，有四种类型

classpath: - resources loaded from the classpath.
file: - resources loaded as a URL, from the filesystem.
http: - resources loaded as a URL.
(none) - resources relative to the ROOT

话虽如此，您的conf可能是

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/externalvideo/**")
            .addResourceLocations("file:/home/myHomedir/videoLocationPath");
    registry.addResourceHandler("/externalthumb/**")
            .addResourceLocations("file:/home/myHomedir/thumbnailLocation");
}

<video width="560" height="340" controls>
    <img src="<c:url value="../externalthumb/to/myvideo.jpg"/>" />
    <source src="<c:url value="../externalvideo/to/myvideo.mp4"/>" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
    <source src="<c:url value="../externalvideo/myvideo.ogv"/>" type='video/ogg; codecs="theora, vorbis"'>
 </video>

与CSS include类似，视频标签应该是

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/externalvideo/**")
            .addResourceLocations("file:/home/myHomedir/videoLocationPath");
    registry.addResourceHandler("/externalthumb/**")
            .addResourceLocations("file:/home/myHomedir/thumbnailLocation");
}

<video width="560" height="340" controls>
    <img src="<c:url value="../externalthumb/to/myvideo.jpg"/>" />
    <source src="<c:url value="../externalvideo/to/myvideo.mp4"/>" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
    <source src="<c:url value="../externalvideo/myvideo.ogv"/>" type='video/ogg; codecs="theora, vorbis"'>
 </video>

我尝试了你的代码，但我最终在我的源代码上看到了这一点，而且视频也没有显示：这是源代码的结果，我也尝试过根据链接显示进行更改file:///home/myHomedir/videoLocationPath 代替文件：/home/myHomedir/videoLocationPath有什么帮助吗？
