Question

将新的UI更改部署到Spring Web应用程序时遇到缓存问题。静态资产（JS / CSS）URL未引用版本路径。有想法吗？

我已经编写了一个Spring MVC（4.3.5）Web应用程序，该应用程序使用Freemarker（2.3.28）进行模板化。我已经参考了许多有关使用Freemarker / Thymeleaf / Velocity在Spring MVC中对静态资产进行版本控制的资源。我目前正在使用VersionResourceResolver，其中包含用于CSS文件的ContentVersionStrategy和用于JS文件的FixedVersionStrategy。我还使用ResourceUrlEncodingFilter基本上将对版本化静态资产的请求转换为实际文件，以防止出现缓存问题。我在Freemarker中利用spring宏来获取我已版本化的静态资源的完整上下文路径。我引用的所有资源都指定要确切地利用我在代码中所做的工作，并且所有这些都显示出有效的产品。但是，我的应用程序仍然尝试检索非版本化的静态文件。带有静态资源URL的HTML文件尚未重写为版本化的URL，我已阅读的每个资源都显示了更改。

    Map<String, VersionStrategy> resolverStrategies = new HashMap<>();
    resolverStrategies.put("/**/*.css", new ContentVersionStrategy());
    resolverStrategies.put("/**/*.js", new FixedVersionStrategy(version));
    VersionResourceResolver versionResourceResolver = new VersionResourceResolver();
    versionResourceResolver.setStrategyMap(resolverStrategies);

    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/")
            .cachePeriod(3600)

    fmResolver.setApplicationContext(ctx);
    resolvers.add(fmResolver);

    BeanNameViewResolver beanResolver = new BeanNameViewResolver();
    beanResolver.setApplicationContext(ctx);
    resolvers.add(beanResolver);

    ContentNegotiatingViewResolver top = new ContentNegotiatingViewResolver();
    top.setViewResolvers(resolvers);

apps.html

<#import "spring.ftl" as spring />
<script src="<@spring.url '../resources/services.js'/>"></script>
<script src="<@spring.url '../resources/metrics.js'/>"></script>
<script src="<@spring.url '../resources/common.js'/>"></script>
<script src="<@spring.url '../static/apps/controllers/main.js'/>"></script>
<script src="<@spring.url '../static/apps/controllers/dashboard.js'/>"></script>
<link href="<@spring.url '../static/apps/apps.css'/>">
...

我希望脚本URL和链接hrefs可以转换为版本URL，而不是非版本URL。当前没有使用当前代码的情况。

示例

<script src="<@spring.url '../static/apps/controllers/dashboard.js'/>"></script>应该转换为<script src="/static/<static-version>/apps/controllers/dashboard.js"></script>，但是，它转换为<script src="/static/apps/controllers/dashboard.js"></script>

<link href="<@spring.url '../static/apps/apps.css'/>">应该转换为<link href="/static/apps/apps-<md5-hash>.css">，但是，它转换为<link href="/static/apps/apps.css">
