springboot 拦截器 通配符

Question

springboot的拦截器 addResourceLocations 这个不能写通配符吗？为什么我写了\*静态资源就访问不到了

Answer 1

是的,这里必须是个有效的目录，且要以/结尾

    /**
     * Add one or more resource locations from which to serve static content.
     * Each location must point to a valid directory. Multiple locations may
     * be specified as a comma-separated list, and the locations will be checked
     * for a given resource in the order specified.
     * <p>For example, {{@code "/"}, {@code "classpath:/META-INF/public-web-resources/"}}
     * allows resources to be served both from the web application root and
     * from any JAR on the classpath that contains a
     * {@code /META-INF/public-web-resources/} directory, with resources in the
     * web application root taking precedence.
     * <p>For {@link org.springframework.core.io.UrlResource URL-based resources}
     * (e.g. files, HTTP URLs, etc) this method supports a special prefix to
     * indicate the charset associated with the URL so that relative paths
     * appended to it can be encoded correctly, e.g.
     * {@code [charset=Windows-31J]https://example.org/path}.
     * @return the same {@link ResourceHandlerRegistration} instance, for
     * chained method invocation
     */
    public ResourceHandlerRegistration addResourceLocations(String... locations) {
        this.locationValues.addAll(Arrays.asList(locations));
        return this;
    }
