css - spring boot静态内容

Question

我在使用 Spring Boot 提供静态内容时遇到问题。

我使用的是默认配置位置:src/main/resources/static/css 和 src/main/resources/static/js。

当页面加载时，我得到所有静态内容的 404。我什至将 permitAll 添加到我的安全设置中。

@Override
protected void configure(HttpSecurity http) throws Exception {
  http
    .authorizeRequests()    
      .antMatchers("/css/**","/js/**").permitAll()
      .antMatchers("/services/**").hasRole("PREAUTH_USER")
      .antMatchers("/", "/dashboard").permitAll()
      .anyRequest().authenticated()
    .and()
      .formLogin().loginPage("/login")
      .permitAll()
    .and()
      .logout()
      .permitAll();
}

我的资源处理程序:

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) { 
  registry.addResourceHandler("/**").addResourceLocations("/");
}

...当我点击 login 时，我的 CSS 返回 404:http://localhost:8080/login

这里是响应头:

Answer 1

问题似乎是当我在我的 appConfig 类中扩展 WebMvcConfigurationSupport(我需要配置消息转换器)时，WebMvcAutoConfiguration 被禁用。所以我不得不添加

private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
        "classpath:/META-INF/resources/", "classpath:/resources/",
        "classpath:/static/", "classpath:/public/" };

和

   @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
if (!registry.hasMappingForPattern("/webjars/**")) {
    registry.addResourceHandler("/webjars/**").addResourceLocations(
            "classpath:/META-INF/resources/webjars/");
}
if (!registry.hasMappingForPattern("/**")) {
    registry.addResourceHandler("/**").addResourceLocations(
            CLASSPATH_RESOURCE_LOCATIONS);
}

编辑:上面的代码不是必需的。我更改了我的配置类以扩展 WebMvcConfigurerAdapter 并且不需要进行上述更改。请参阅@AndyWilkinson 的以下评论
