Spring MVC和Thymeleaf资源版本控制 [英] Spring MVC and Thymeleaf Resource Versioning

问题描述

我正在尝试使用Spring Mvc 4进行资源版本控制。我使用thymeleaf模板引擎。但不适用于以下代码。加载页面时，我在查看页面源代码时看不到新版本的网址。那么我的代码有什么问题？我想念什么？

I am trying resource versioning with Spring Mvc 4.I use thymeleaf template engine.But doesnt work with the following code.When load the page I cant see new version Url when i view the page source.So what's the problem in my code? what am i miss?

@Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/static/theme*//**").addResourceLocations("/resources/static/theme/")
            .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS))
            .resourceChain(false)
            .addResolver(new VersionResourceResolver().addContentVersionStrategy("/**"))
            .addTransformer(new CssLinkResourceTransformer());
    registry.addResourceHandler("/static*//**").addResourceLocations("/resources/static/")
            .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS))
            .resourceChain(false)
            .addResolver(new VersionResourceResolver().addContentVersionStrategy("/**"))
            .addTransformer(new CssLinkResourceTransformer());
    registry.addResourceHandler("/static/js*//**").addResourceLocations("/resources/static/js/")
            .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS))
            .resourceChain(false)
            .addResolver(new VersionResourceResolver().addContentVersionStrategy("/**"))
            .addTransformer(new CssLinkResourceTransformer());
}

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

我在脚本标记中使用了表达式。
th：src = @ {/ resources / static / js / companyList.js}

I am using with expression in script tag. th:src="@{/resources/static/js/companyList.js}"

推荐答案

这是我的解决方案。我调试Spring.ServletContextResource类的源代码，创建一个relativeRelative。然后检查资源是否存在。

Here is the my solution.I debug source code of Spring.ServletContextResource class create a relativeRelative.Then check whether resource is exists.

资源位置：/资源/静态/

Resource location : /resources/static/

路径：/static/css/login.css

Path : /static/css/login.css

pathToUse：/ resources / static /static/css/login.css->此资源网址不存在，因此返回null。

pathToUse : /resources/static/static/css/login.css --> this resource url not exists so return null.

ServletContextResource类

@Override
public Resource createRelative(String relativePath) {
    String pathToUse = StringUtils.applyRelativePath(this.path, relativePath);
    return new ServletContextResource(this.servletContext, pathToUse);
}

解决方案：
资源位置： / resources / static /

Solution: Resource location : /resources/static/

路径：/css/login.css

Path : /css/login.css

pathToUse：/ resources / static / css / login.css

pathToUse : /resources/static/css/login.css

现在我包括此格式。从路径中删除/资源。

Now I include this format.Remove /resources from path.

th：src = @ {/ css / login.css}

           @Override
           public void addResourceHandlers(final ResourceHandlerRegistry registry) 
           {

                registry.addResourceHandler("/theme*//**").addResourceLocations("/resources/static/")
                        .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS))
                        .resourceChain(false)
                        .addResolver(new VersionResourceResolver().addContentVersionStrategy("/**"))
                        .addTransformer(new CssLinkResourceTransformer());
                registry.addResourceHandler("/css*//**").addResourceLocations("/resources/static/")
                        .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS))
                        .resourceChain(false)
                        .addResolver(new VersionResourceResolver().addContentVersionStrategy("/**"))
                        .addTransformer(new CssLinkResourceTransformer());
                registry.addResourceHandler("/js*//**").addResourceLocations("/resources/static/")
                        .setCacheControl(CacheControl.maxAge(365, TimeUnit.DAYS))
                        .resourceChain(false)
                        .addResolver(new VersionResourceResolver().addContentVersionStrategy("/**"))
                        .addTransformer(new CssLinkResourceTransformer());

         @Override
         public void configure(final WebSecurity web) throws Exception {
 web.ignoring().antMatchers("/theme/**").antMatchers("/js/**").antMatchers("/css/**");
            }
