Question

我有以下百里香的html页面：

<head th:fragment="header">

    <meta charset="utf-8" />
    <link rel="stylesheet" href="../../css/main.css" th:href="@{/css/main.css}" />
    <title th:text="#{device.page.title}">Title</title>
</head>

<body>
<div>
    <h1 th:text="#{device.table.caption}"></h1>
    <hr class="fineline"/>
    Select devices using the checkboxes, you can update the client version or add client commands.
    <form action="#" th:action="@{/devices/modify}" th:object="${deviceCommand}" method="post">
    <table border="0" cellpadding="0" cellspacing="0" class="touchTable">
        <!--<thead> -->
            <tr>
                <td scope="col" th:text="#{device.check.label}">Select</td>
                <td width="300" scope="col"><span th:text="#{device.id.label}"></span>&nbsp;(<span th:text="#{device.retailer.name.label}"></span>)</td>
                <td scope="col" th:text="#{device.current.label}">Curr Version</td>
                <td scope="col" th:text="#{device.next.label}">Next Version</td>
                <td scope="col" th:text="#{device.commands.label}">Commands</td>
            </tr>
        <!--</thead>-->
        <!--<tbody> -->
            <tr th:each="d : ${devices}">
                <td><input type="checkbox" th:field="*{deviceModificationIds}" th:value="${d.id}"/></td>
                <td><span th:text="${d.id}"></span>&nbsp;(<span th:text="${d.retailerName}"></span>)</td>
                <td th:text="${d.currentClientVersion}">Washington</td>
                <td th:text="${d.nextClientVersion}">gwash</td>
                <td th:text="${d.commands}">gwash</td>
            </tr>
            <tr>
                <td colspan="2"></td>
                <td><span th:text="#{device.change.version.label}"></span><br/><input type="text" th:field="*{newVersion}"/></td>
                <td><span th:text="#{device.add.command.label}"></span><br/><input type="text" th:field="*{newCommand}"/></td>
                <td><br/><button type="submit" th:text="#{device.modify.action.button}">Action</button></td>
            </tr>
        <!--</tbody>  -->
    </table>
    </form>


</div>
</body>

问题在于css样式表。基本上春天似乎无法找到它，鄙视我将文件放在/resources/static/css/main.css

它返回错误（在日志中）：

o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/css/main.css] in DispatcherServlet with name 'dispatcherServlet'

现在doco都说Spring Boot应该自动提供/ resources / static

中的东西

这是我的WebConfig：

@Configuration
@ComponentScan("com.txxxxcorp.txxxxpoint.resource")
@EnableWebMvc
public class WebConfig {

    @Bean
    MultipartConfigElement multipartConfigElement() {
        MultiPartConfigFactory factory = new MultiPartConfigFactory();
        factory.setMaxFileSize("4096KB");
        factory.setMaxRequestSize("4096KB");
        return factory.createMultipartConfig();
    }

    @Bean  
    public ViewResolver viewResolver() {
        ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
        templateResolver.setTemplateMode("XHTML");
        templateResolver.setPrefix("templates/");
        templateResolver.setSuffix(".html");

        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setTemplateResolver(templateResolver);

        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(engine);

        String[] excludedViews = new String[]{
            "/resources/static/**"};
        viewResolver.setExcludedViewNames(excludedViews);

        return viewResolver;
    }

    @Bean
    public EmbeddedServletContainerCustomizer servletContainerCustomizer() {
        return new EmbeddedServletContainerCustomizer() {
            @Override
            public void customize(ConfigurableEmbeddedServletContainer servletContainer) {
                ((TomcatEmbeddedServletContainerFactory) servletContainer).addConnectorCustomizers(
                        new TomcatConnectorCustomizer() {
                            @Override
                            public void customize(Connector connector) {
                                AbstractHttp11Protocol httpProtocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
                                httpProtocol.setCompression("on");
                                httpProtocol.setCompressionMinSize(256);
                                String mimeTypes = httpProtocol.getCompressableMimeTypes();
                                String mimeTypesWithJson = mimeTypes + "," + MediaType.APPLICATION_JSON_VALUE;
                                httpProtocol.setCompressableMimeTypes(mimeTypesWithJson);
                            }
                        }
                );
            }
        };
    }

    @Bean
    public ResourceBundleMessageSource messageSource() {
        ResourceBundleMessageSource source = new ResourceBundleMessageSource();
        source.setBasename("messages");
        return source;
    }

由于某种原因，编辑器不允许我插入spring安全配置而不抱怨其格式不正确（IntelliJ，Maven和Spring Boot不同意这一点，因为它编译和工作），请放心，我已经允许/css/main.css要经历的路径

有谁知道为什么我无法解析css文件？

Answer 1

您使用@EnableWebMvc这一事实将关闭Spring Boot的MVC自动配置（以及静态资源处理）。

要启用静态资源处理，最佳解决方案是删除@EnableWebMvc并让Spring Boot执行最佳功能 - 自动配置。

在更改之后，您应该进行一些回归测试，以确保没有其他任何打破

Answer 2

@ geoand＆＃39; s答案是正确的，当您使用@enablWebMvc时，您的应用程序的静态资源已关闭。所以你在这里使用的任何css文件都是由thyemeleaf解析的，你需要声明该类继承WebMvcAutoConfigurationAdapter并覆盖addResourceHandlers方法，代码可能如下所示：

 @Configuration
    @ComponentScan("com.txxxxcorp.txxxxpoint.resource")
    @EnableWebMvc
    public class WebConfig extends WebMvcConfigurerAdapter {

 @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        String[] STATIC_RESOURCE = {"/","classpath:/","classpath:/META-INF/resources/", "classpath:/META-INF/resources/webjars/",
                "classpath:/resources/", "classpath:/static/", "classpath:/public/"};

        if (!registry.hasMappingForPattern("/**")) {
            registry.addResourceHandler("/**").addResourceLocations(STATIC_RESOURCE);
        }
    }

.......................
}

Answer 3

我不得不将百里香叶依赖性添加到pom中。没有这种依赖性，Spring Boot找不到静态资源。

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

Spring Boot不使用Thymeleaf提供静态内容
