Spring Boot单页应用程序-将每个请求转发到index.html [英] Spring boot single page application - forward every request to index.html

问题描述

我有一个Spring Boot(v1.3.6)单页应用程序(angular2)，我想将所有请求转发到index.html.

I have a Spring Boot (v1.3.6) single page application (angular2) and i want to forward all request to the index.html.

对 http://localhost:8080/index.html 的请求有效(200和i获取index.html)，但 http://localhost:8080/home 不是(404).

A request to http://localhost:8080/index.html is working (200 and i get the index.html) but http://localhost:8080/home is not (404).

Runner.class

Runner.class

@SpringBootApplication
@ComponentScan({"packagea.packageb"})
@EnableAutoConfiguration
public class Runner {

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

WebAppConfig.class

WebAppConfig.class

@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);
    }

}

styles.css，/app/third-party/xyz/xyz.js，..正在工作(200，并且我得到了正确的文件).仅/**至index.html不起作用.

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

推荐答案

您还可以添加转发控制器，例如:

You can also add a forwarding controller like:

@Controller
public class ForwardingController {
    @RequestMapping("/{path:[^\\.]+}/**")
    public String forward() {
        return "forward:/";
    }
}

第一部分{path:[^\\.]+}与.以外的任何一个或多个字符匹配.这确保了file.ext的请求不会被此RequestMapping处理.如果需要支持也转发子路径，请将/**放在{...}之外.

The first part {path:[^\\.]+} matches one or more of any character other than .. This makes sure request for a file.ext doesn't get handled by this RequestMapping. If you need to support sub-paths to also be forwarded, put /** outside of the {...}.
