Spring boot mapping static html

问题:

I want to create spring boot web application.

I have two static html files: one.html, two.html.

I want to map them as follows

localhost:8080/one
localhost:8080/two

without using template engines (Thymeleaf).

How to do that? I have tried many ways to do that, but I have 404 error or 500 error (Circular view path [one.html]: would dispatch back to the current handler URL).

OneController.java is:

@Controller
public class OneController {
    @RequestMapping("/one")
    public String one() {
        return "static/one.html";
    }
}

Please update your WebMvcConfig and include UrlBasedViewResolver and /static resource handler. Mine WebConfig class looks as follows:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

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

    @Bean
    public ViewResolver viewResolver() {
        UrlBasedViewResolver viewResolver = new UrlBasedViewResolver();
        viewResolver.setViewClass(InternalResourceView.class);
        return viewResolver;
    }

}

I have checked it and seems working.

Maciej's answer is based on browser's redirect. My solution returns static without browser interaction.

In my case I want to map all sub paths to the same file but keep the browser path as the original requested, at same time I use thymeleaf then I don't want to override it's resolver.

@Controller
public class Controller {

    @Value("${:classpath:/hawtio-static/index.html}")
    private Resource index;

    @GetMapping(value = {"/jmx/*", "/jvm/*"}, produces = MediaType.TEXT_HTML_VALUE)
    @ResponseBody
    public ResponseEntity actions() throws IOException {
        return ResponseEntity.ok(new InputStreamResource(index.getInputStream()));
    }
}

Obs. every hit will read the data from the index.html file, it will not be cached

If you don't care about additional browser redirect you can use this:

@Controller
public class OneController {
    @RequestMapping("/one")
    public String one() {
        return "redirect:/static/one.html";
    }
}
