I start my web application with spring boot. It use a simple main class to start an embedded tomcat server:

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application {

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

}

I want to configure the server in the way that he can handle angularjs html5mode that will be activated with 

$locationProvider.html5Mode(true);

Relevant postings from other users shows that you need to redirect to the root. the html5 mode remove the hashbag from the url. If you refresh the page the server doesnt find the page cause he do not handle the hash. see: AngularJS - Why when changing url address $routeProvider doesn't seem to work and I get a 404 error

I don't think there's enough information there to know what you did, and why it didn't work. – Dave Syer Jul 19 '14 at 7:11

I had same problem. As far as I know, in html5 mode, angularjs don't resolve hash but entered url or url added through pushState.

The problem was that PathResourceResolver map directories but not files. Because it intended to serve requested files from directory but not to rewrite urls. For app it's mean, if you refresh your browser window or type url like http://example.com/mystate, it's query "/mystate" from the server. If spring don't know url, they return 404. One of the solutions is map every possible state to index.html like here (source, btw look at webjars - it's great!). But in my case I can safely map "/**" to index.html and therefore my solution is to override PathResourceResolver#getResource:

@Configuration
@EnableConfigurationProperties({ ResourceProperties.class })
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    @Autowired
    private ResourceProperties resourceProperties = new ResourceProperties();

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        Integer cachePeriod = resourceProperties.getCachePeriod();

        registry.addResourceHandler("/static/**")
                .addResourceLocations("classpath:/static/")
                .setCachePeriod(cachePeriod);

        registry.addResourceHandler("/**")
                .addResourceLocations("classpath:/static/index.html")
                .setCachePeriod(cachePeriod).resourceChain(true)
                .addResolver(new PathResourceResolver() {
                    @Override
                    protected Resource getResource(String resourcePath,
                            Resource location) throws IOException {
                        return location.exists() && location.isReadable() ? location
                                : null;
                    }
                });
    }
}

I can't get this to work with other static resources included within index.html i.e. JS and CSS resources. For example I have another css file in my static folder and I link to it within the head section of my index.html file. When I look at that file in Chrome Dev Tools, it's contents are index.html. – tlavarea Jan 28 '15 at 2:31

I ended up manually mapping the angular routes to a specific controller that forwards to index.html as per your linked source. It works fine and is clear and easy to understand :) – Sébastien Tromp Oct 5 '15 at 13:32

I found a solution I can live with it.

@Controller
public class ViewController {

    @RequestMapping("/")
    public String index() {
        return "index";
    }

    @RequestMapping("/app/**")
    public String app() {
        return "index";
    }
}

The angularjs app has to be under the subdomain app. If you do not want that you could create a subdomain like app.subdomain.com that mapps to your subdomain app. With this construct you have no conflicts with webjars, statis content and so on.

Could you elaborate how this works? For me it returns only the string "index"! my index.html is under resources/static/app – sansari Jul 18 '16 at 23:10
    
The purpose of the html5mode is to avoid using a # prefix. You're replacing it with a app prefix, so what is the value. Better just use the hash based routing strategy. – rcomblen Sep 2 '16 at 7:22

A small adjustment to a previous code which works to me.

// Running with Spring Boot v1.3.0.RELEASE, Spring v4.2.3.RELEASE
@Configuration
@EnableConfigurationProperties({ ResourceProperties.class })
public class WebMvcConfig extends WebMvcConfigurerAdapter {

@Autowired
private ResourceProperties resourceProperties = new ResourceProperties();

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    Integer cachePeriod = resourceProperties.getCachePeriod();

    final String[] staticLocations = resourceProperties.getStaticLocations();
    final String[] indexLocations  = new String[staticLocations.length];
    for (int i = 0; i < staticLocations.length; i++) {
        indexLocations[i] = staticLocations[i] + "index.html";
    }
    registry.addResourceHandler(
            "/**/*.css",
            "/**/*.html",
            "/**/*.js",
            "/**/*.json",
            "/**/*.bmp",
            "/**/*.jpeg",
            "/**/*.jpg",
            "/**/*.png",
            "/**/*.ttf",
            "/**/*.eot",
            "/**/*.svg",
            "/**/*.woff",
            "/**/*.woff2"
            )
            .addResourceLocations(staticLocations)
            .setCachePeriod(cachePeriod);

    registry.addResourceHandler("/**")
            .addResourceLocations(indexLocations)
            .setCachePeriod(cachePeriod)
            .resourceChain(true)
            .addResolver(new PathResourceResolver() {
                @Override
                protected Resource getResource(String resourcePath,
                        Resource location) throws IOException {
                    return location.exists() && location.isReadable() ? location
                            : null;
                }
            });
}

}

I just encountered the similar issue where I wanted to configure Resources and at the same time I wanted to use AngularJS Html5 mode enabled.

In my case my static files were served from /public route so I used the following request mapping on my index action and it all works fine.

@RequestMapping(value = {"", "/", "/{[path:(?!public).*}/**"}, method = GET)
public String indexAction() {
    return "index";
}

You can forward all not found resources to your main page by providing custom ErrorViewResolver. All you need to do is to add this to your @Configuration class:

@Bean
ErrorViewResolver supportPathBasedLocationStrategyWithoutHashes() {
    return new ErrorViewResolver() {
        @Override
        public ModelAndView resolveErrorView(HttpServletRequest request, HttpStatus status, Map<String, Object> model) {
            return status == HttpStatus.NOT_FOUND
                    ? new ModelAndView("index.html", Collections.<String, Object>emptyMap(), HttpStatus.OK)
                    : null;
        }
    };
}
