我有一个Spring MVC(4.3.0)应用程序,并注册了一个VersionResourceResolver,并在ResourceHandlerRegistry中添加了ContentVersionStrategy.我启用了ResourceUrlEncodingFilter.

    @Bean
    public ResourceUrlEncodingFilter resourceUrlEncodingFilter() {
        return new ResourceUrlEncodingFilter();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        boolean devMode = this.env.acceptsProfiles("local");
        //boolean useResourceCache = !devMode;
        Integer cachePeriod = devMode ? 0 : (60 * 60 * 24 * 365); //If dev clear cache else 1 year

        registry.addResourceHandler("/resources/**")
                .addResourceLocations("/resources/")
                .setCachePeriod(cachePeriod)
                .resourceChain(false)
                .addResolver(new VersionResourceResolver()
                    .addContentVersionStrategy("/**"))
                .addTransformer(new AppCacheManifestTransformer());
}

当我使用c:url或spring:url标签访问JSP页面上的/ resources(JS,Images,CSS等)中的任何内容时,"versioned"URL不显示(意思是:URL中没有哈希代码) .例:

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

在检查页面时生成:/myapp/resources/css/views/login.css作为URL字符串.

但是,如果我在Controller中使用ResourceURLProvider,我确实在URL中看到了哈希码:

@Autowired
private ResourceUrlProvider mvcResourceUrlProvider;

@RequestMapping(value = { "/" }, method = RequestMethod.GET) …
