Spring boot single page application - forward every request to index.html : <p>I have a Spring Boot (v1.3.6) single page application (angular2) and i want to forward all request to the <code>index.html</code>.</p>

<p>A request to <a href="http://localhost:8080/index.html" rel="noreferrer">http://localhost:8080/index.html</a> is working (200 and i get the index.html) but <a href="http://localhost:8080/home" rel="noreferrer">http://localhost:8080/home</a> is not (404).</p>

<p>Runner.class</p>

<pre><code>@SpringBootApplication
@ComponentScan({"packagea.packageb"})
@EnableAutoConfiguration
public class Runner {

    public static void main(String[] args) throws Exception {
        ConfigurableApplicationContext run = SpringApplication.run(Runner.class, args);
    }
}
</code></pre>

<p>WebAppConfig.class</p>

<pre><code>@Configuration
@EnableScheduling
@EnableAsync
public class WebAppConfig extends WebMvcConfigurationSupport {

    private static final int CACHE_PERIOD_ONE_YEAR = 31536000;

    private static final int CACHE_PERIOD_NO_CACHE = 0;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.setOrder(-1);
        registry.addResourceHandler("/styles.css").addResourceLocations("/styles.css").setCachePeriod(CACHE_PERIOD_ONE_YEAR);
        registry.addResourceHandler("/app/third-party/**").addResourceLocations("/node_modules/").setCachePeriod(CACHE_PERIOD_ONE_YEAR);
        registry.addResourceHandler("/app/**").addResourceLocations("/app/").setCachePeriod(CACHE_PERIOD_NO_CACHE);
        registry.addResourceHandler("/systemjs.config.js").addResourceLocations("/systemjs.config.js").setCachePeriod(CACHE_PERIOD_NO_CACHE);
        registry.addResourceHandler("/**").addResourceLocations("/index.html").setCachePeriod(CACHE_PERIOD_NO_CACHE);
    }

}
</code></pre>

<p><code>styles.css</code>, <code>/app/third-party/xyz/xyz.js</code>,.. are working (200 and i get the correct file). Only <code>/**</code> to <code>index.html</code> is not working.</p>
