Spring Boot 2.1.3。发布，我想swagger-ui.html作为主页/欢迎页面和handel ROOT上下文（/）

Question

我有spring boot 2和swagger API页面http://localhost:8448/portalapi/swagger-用户界面。html。但我想绘制地图http://localhost:8448/和http://localhost:8448/portalapi/将请求转发给http://localhost:8448/portalapi/swagger-用户界面。html。但它不起作用。它给出HTTP状态404–未找到（tomcat默认响应）。非常感谢您的帮助或指点。

appliacation.properties

##
# tomcat server port
server.port=8448
#server.address=0.0.0.0

server.servlet.contextPath=/portalapi/

这是一个webconfig类，用于上下文转发：

   @Configurable
    @Component
    public class WebConfig implements WebMvcConfigurer {

        @Override
        public void addViewControllers(ViewControllerRegistry registry) {
            // forward requests to /admin and /user to their index.html
            registry.addViewController("/").setViewName(
                    "forward:/portalapi/swagger-ui.html");
            registry.addViewController("/portalapi/").setViewName(
                    "forward:/portalapi/swagger-ui.html");
        }

    }

Answer 1

试试重定向控制器

@Controller
public class RedirectController {

    @RequestMapping(value = {"/","/portalapi/"})
    public String redirectToSwagger() {
        return "redirect:/portalapi/swagger-ui.html";
    }

}

Answer 2

从以下部分更改：

@Configurable
@Component
public class WebConfig implements WebMvcConfigurer {

收件人：

@Configuration
public class WebConfig implements WebMvcConfigurer {
