Spring-addResourceHandlers无法使用Rest Controller解决静态资源

Question

我有以下问题。 当使用ResourceHandlers配置Spring WebMVC应用程序，并使用带有特殊@RequestMapping的RestController类时，将不会提供静态资源，而是会调用RestController。

这是代码：

@Configuration
@ServletComponentScan
@EnableWebMvc
public class Main extends SpringBootServletInitializer implements ServletContextAware, WebMvcConfigurer {

    public static void main(String[] args) {
        SpringApplication.run(Main.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(new Class[]{Main.class, Initializer.class, ContainerInitializer.class});
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new FacesServlet(), "*.jsf");
        servletRegistrationBean.setName("JSF Faces Servlet");
        servletRegistrationBean.setLoadOnStartup(1);
        return servletRegistrationBean;
    }

    @Bean
    public ServletRegistrationBean facesServletRegistratiton() {
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new FacesServlet(), new String[]{"*.xhtml"});
        servletRegistrationBean.setName("XHTML Faces Servlet");
        servletRegistrationBean.setLoadOnStartup(1);
        return servletRegistrationBean;
    }

    @Override
    public void setServletContext(ServletContext servletContext) {
        servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

       // Register resource handler for CSS and JS
       registry.addResourceHandler("/resources/**").addResourceLocations("/WEB-INF/resources/")
            .setCacheControl(CacheControl.maxAge(2, TimeUnit.HOURS).cachePublic())
            .resourceChain(true)
            .addResolver(new PathResourceResolver());

       // Register resource handler for images
       registry.addResourceHandler("/images/**").addResourceLocations("/WEB-INF/images/")
            .setCacheControl(CacheControl.maxAge(2, TimeUnit.HOURS).cachePublic())
            .resourceChain(true)
            .addResolver(new PathResourceResolver());
    }
}

因此，我在资源文件夹中有两个用于处理静态资源（如css，js文件）和用于静态图像的图像文件夹的资源处理程序。

我的RestController类的代码如下所示：

@RestController
@Component
public class Clownfish {
   @GetMapping(path = "/{name}/**")
   public void universalGet(@PathVariable("name") String name, @Context HttpServletRequest request, @Context HttpServletResponse response) {
         String path = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
         if (name.compareToIgnoreCase(path) != 0) {
             name = path.substring(1);
         }
    }
}

当使用http：// localhost：8080 / images / foo.png调用我的资源时，将调用RestController。 如果我将@GetMapping(path = "/{name}/**")更改为@GetMapping(path = "/{name}")它可以正常工作。 但是我需要通配符来处理特殊呼叫。

我的配置在做什么错？ TIA

我找到了一种设置ResourceHandler优先级的方法。

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

       // Register resource handler for CSS and JS
       registry.addResourceHandler("/resources/**").addResourceLocations("/WEB-INF/resources/")
            .setCacheControl(CacheControl.maxAge(2, TimeUnit.HOURS).cachePublic())
            .resourceChain(true)
            .addResolver(new PathResourceResolver());

       // Register resource handler for images
       registry.addResourceHandler("/images/**").addResourceLocations("/WEB-INF/images/")
            .setCacheControl(CacheControl.maxAge(2, TimeUnit.HOURS).cachePublic())
            .resourceChain(true)
            .addResolver(new PathResourceResolver());
       registry.setOrder(-1);  // This will set the priority lower to the default handler (that is by default 0)
    }
