Spring boot single page application - forward every request to index.html
提问by Christoph
I have a Spring Boot (v1.3.6) single page application (angular2) and i want to forward all request to the index.html.
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.
A request to http://localhost:8080/index.htmlis working (200 and i get the index.html) but http://localhost:8080/homeis not (404).
对http://localhost:8080/index.html的请求正在工作（200，我得到了 index.html）但http://localhost:8080/home不是（404）。

styles.css, /app/third-party/xyz/xyz.js,.. are working (200 and i get the correct file). Only /**to index.htmlis not working.
styles.css, /app/third-party/xyz/xyz.js,.. 正在工作（200 并且我得到了正确的文件）。只有/**到index.html不起作用。

You can also add a forwarding controller like:
您还可以添加一个转发控制器，如：
@Controller
public class ForwardingController {
@RequestMapping("/{path:[^\.]+}/**")
public String forward() {
return "forward:/";
}
}
The first part {path:[^\\.]+}matches one or more of any character other than .. This makes sure request for a file.extdoesn't get handled by this RequestMapping. If you need to support sub-paths to also be forwarded, put /**outside of the {...}.
第一部分{path:[^\\.]+}匹配一个或多个除.. 这可确保file.ext此 RequestMapping 不会处理对 a 的请求。如果您需要支持子路径也被转发，放/**外面{...}。

Without looking at logs I'm not entirely sure why its not being mapped correctly, however if you want to map URLs to a view (HTML) then you will probably be better off using the viewControllermechanism spring provides http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html#mvc-config-view-controller. e.g.
在不查看日志的情况下，我不完全确定为什么它没有被正确映射，但是如果您想将 URL 映射到视图（HTML），那么您可能最好使用viewControllerspring 提供的机制http://docs.spring。 io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html#mvc-config-view-controller。例如
@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("home");
}
}
(taken from spring docs linked above - this is how you should map a url to a view rather than re-purposing the mapping for static resources.)
（取自上面链接的 spring 文档 - 这是您应该如何将 url 映射到视图，而不是重新使用静态资源的映射。）
I'm not sure if there is any kind of suffix filtering for the resource mapping - e.g. I don't know how spring decides to map requests to the ResourceHttpRequestHandler- have you tried (just to confirm or deny) whether something like http://localhost:8080/home.htmlamps to anything?
我不确定资源映射是否有任何类型的后缀过滤 - 例如，我不知道 spring 如何决定将请求映射到ResourceHttpRequestHandler- 您是否尝试过（只是为了确认或拒绝）是否像http://本地主机:8080/home.html放大器到任何东西？
It's also possible that the html mapping you have defined above is just being ignored and the index.html is just working because of Spring-Boot's default home page behaviour: https://github.com/spring-projects/spring-boot/blob/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/ResourceProperties.java#L108
由于 Spring-Boot 的默认主页行为，您在上面定义的 html 映射也有可能被忽略，而 index.html 正在工作：https: //github.com/spring-projects/spring-boot/blob /master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/ResourceProperties.java#L108

This one didn't work for me:
这个对我不起作用：
return "forward:/";
Thanks to Spring MVC @RestController and redirectI found a nicely working solution:
感谢Spring MVC @RestController 和重定向，我找到了一个很好的解决方案：
@RequestMapping(value = "/{[path:[^\.]*}")
public void redirect(HttpServletResponse response) throws IOException {
response.sendRedirect("/");
}

I had the same problem and the following worked for me. My html files are inside src/main/resources/static/app
我遇到了同样的问题，以下对我有用。我的 html 文件在 src/main/resources/static/app 里面
The key was to remove @EnableWebMvc and add "classpath:/static/app/" to addResourceLocations! Hope this helps.
关键是删除@EnableWebMvc 并将“classpath:/static/app/”添加到addResourceLocations！希望这可以帮助。
private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
"classpath:/META-INF/resources/", "classpath:/resources/",
"classpath:/static/","classpath:/static/app/", "classpath:/public/" };
@Bean
public WebMvcConfigurer webMvcConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
if (!registry.hasMappingForPattern("/webjars/**")) {
registry.addResourceHandler("/webjars/**").addResourceLocations(
"classpath:/META-INF/resources/webjars/");
}
if (!registry.hasMappingForPattern("/**")) {
registry.addResourceHandler("/**").addResourceLocations(
CLASSPATH_RESOURCE_LOCATIONS);
}
}
@Override
public void addViewControllers(ViewControllerRegistry registry) {
// forward requests to /admin and /user to their index.html
registry.addViewController("/portal").setViewName(
"forward:/app/index.html");
}
};
}
