Spring Boot未返回正确的MIME类型

Question

Spring Boot未返回正确的MIME类型

我正在尝试使用Spring Boot，Spring Security和Thymeleaf制作Spring MVC应用程序。

问题是-当我请求带有html和css的页面时，我没有为css文件获得正确的MIME类型，因此为什么Chrome无法加载状态为“ 已取消 ”和消息“ 拒绝以应用样式”从“ HTTP：//本地主机：8080 /登录 ”，因为它的MIME类型（文本/ html'）不支持的样式表的MIME类型，以及严格的MIME检查已启用。 “

我正确链接了CSS文件：“”

CSS文件包含在：

资源->静态-> CSS-> style.css

我已允许从安全性配置文件中的resources文件夹中获得所有资源：

有任何想法如何解决错误的MIME类型？是否缺少任何配置？

就我而言，我必须允许静态文件请求才能使其正常工作。

@Configuration 
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
 @Overide
 protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
            .antMatchers("/js/**", "/css/**").permitAll()
            .anyRequest().authenticated()
            .and()
        .formLogin()
            .loginPage("/login")
            .permitAll();
  }
}

我一直在为同样的问题苦苦挣扎，我终于意识到这是一个红鲱鱼 - 真正的问题是404，而 MIME 类型错误来自 Spring 对它的处理。正如Spring Boot 文档中所述，其内置的错误处理会自动重定向到/error错误详细信息并将其输出为 JSON。当我检查我的日志时，我404在我的网络服务器访问日志中看到了一个，在我的应用程序日志中看到了以下内容：

DEBUG DispatcherServlet:869 - DispatcherServlet with name 'dispatcherServlet' processing GET request for [/error]
DEBUG RequestMappingHandlerMapping:310 - Looking up handler method for path /error
DEBUG RequestMappingHandlerMapping:317 - Returning handler method [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)]
DEBUG HttpEntityMethodProcessor:234 - Written [{timestamp=Fri Apr 06 14:06:54 PDT 2018, status=404, error=Not Found, message=No message available, path=/css/style.css}] as "application/json" using [org.springframework.http.converter.json.MappingJackson2HttpMessageConverter@5ef96137]

所以，你真正的问题是 Spring 没有找到你的静态资源。您需要确保该resources文件夹在您的类路径中，或者使用该spring.resources.static-locations属性显式设置位置。
