白标错误页面只需输入 URL? [英] Whitelabel Error Page just type on URL?

问题描述

这个 Spring-boot 项目与 Angular 4 集成.输入url地址可以进入首页>> localhost:8080.

This Spring-boot project is integrated with Angular 4. I can reach the home page when type the url adress >> localhost:8080.

当输入任何不同的 url 添加参数时，我得到 whitelabel 错误页面，例如:/login,/signup.

I get whitelabel error page when type any diffent url is added parameter like: /login, /signup.

出现意外错误(类型=未找到，状态=404).

There was an unexpected error (type=Not Found, status=404).

我可以使用 angular-routinglocalhost:8080/signup、localhost:8080/foo、..)>.所以问题是直接打url.

I can reach these pages (localhost:8080/signup, localhost:8080/foo, ..) on website using angular-routing. So the problem is about only hitting url directly.

那么我该如何解决这个问题，任何检查的想法都会有所帮助.

So How can I solve this, any idea to check would be helpful.

注意:这些url在服务器端没有授权.

Note: There is no authorization for these url in server side.

添加了 index.html 路径.

index.html path added.

src/main/resources
  static
    assets
    index.html
    bundle
    bundle
    ..

routing.ts

export const routes: Routes = [
  {
    path: '',
    component: HomeComponent,
    pathMatch: 'full'
  },
  {
    path:'signup',
    component: SignupComponent,
    canActivate: [GuestGuard],
    pathMatch:'full'
  },

推荐答案

我已经直接实现了这个 WebMvcConfigurer 并且它非常适合我.这是参考链接.

I have implemented directly this WebMvcConfigurer and it works perfectly for me. This is the reference link.

import java.io.IOException;

import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.resource.PathResourceResolver;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {

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