我想制作一个 Web 应用程序，所以我从创建外观开始。我的前端很差，所以我想使用现成的模板，例如引导导航栏。我另外使用 thymeleaf 。我复制了示例导航栏，但它看起来像这样:

bad

代替

good

所有 html 文件位于:DrinkShop\src\main\resources\templates和用于测试的 CSS:DrinkShop\src\main\resources\static\css

h1 {
  color:  green;
}

我尝试检查 web 工具，但我得到了 bootstrap，style

状态码:200 OK

最佳答案

可能是您的 Bootstrap 没有配置或配置错误。确保你有一些类看起来像:

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/fontawe/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/font-awesome/5.0.6/web-fonts-with-css/css/");
        registry.addResourceHandler("/resources/bootstrap/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/bootstrap/4.0.0/");
        registry.addResourceHandler("/resources/jquery/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/jquery/3.2.1/");
        registry.addResourceHandler("/resources/popper/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/popper.js/1.12.5/dist/umd/");
    }
}

在 html 中使用类似的东西:

th:href="@{/resources/bootstrap/css/bootstrap.min.css}"
th:href="@{/resources/fontawe/fontawesome-all.min.css}"
th:src="@{/resources/jquery/jquery.min.js}"
th:src="@{/resources/popper/popper.min.js}"
th:src="@{/resources/bootstrap/js/bootstrap.min.js}"

关于java - 不显示div内容，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52331475/
