Question

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

http://localhost:8080/index.html的请求正在运行（200，我得到index.html），但http://localhost:8080/home不是（404）。

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

@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，..正在运行（200，我得到了正确的文件）。只有/**到index.html无效。

Answer 1

您还可以添加转发控制器，如：

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

第一部分{path:[^\\.]+}匹配.以外的任何字符中的一个或多个。这样可以确保请求file.ext的请求不会被此RequestMapping处理。如果您需要支持也可以转发的子路径，请将/**放在{...}之外。

如果不查看日志，我并不完全确定为什么没有正确映射，但是如果要将URL映射到视图（HTML），那么最好使用viewController机制spring提供http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html#mvc-config-view-controller。 e.g。

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

  @Override
  public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("home");
  }

}

（取自上面链接的spring文档 - 这是你应该如何将url映射到视图而不是重新设置静态资源的映射。）

我不确定资源映射是否有任何类型的后缀过滤 - 例如我不知道春天如何决定将请求映射到ResourceHttpRequestHandler - 您是否尝试过（只是为了确认或否认）http://localhost:8080/home.html之类的内容是否适用于任何内容？

上面定义的html映射也可能被忽略，而index.html只是因为Spring-Boot的默认主页行为而工作：https://github.com/spring-projects/spring-boot/blob/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/ResourceProperties.java#L108 < / p>

I had the same problem and the following worked for me. My html files are inside src/main/resources/static/app

The key was to remove @EnableWebMvc and add "classpath:/static/app/" to addResourceLocations! Hope this helps.

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");
        }
    };
}

这个对我不起作用：

return "forward:/";

感谢Spring MVC @RestController and redirect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("/");
}

Spring启动单页应用程序 - 将每个请求转发到index.html
