Question

我正在尝试在Spring Boot应用程序中映射多个请求路径。这是一个RESTful Web服务，但我想为用户界面提供两个视图（主要和帮助）。我已经尝试调整返回字符串的名称（即从“help.html到”帮助“），以及清理我的项目和重建，但我无法理解为什么一个视图解析而另一个视图没有并返回我已经尝试创建一个单独的 HelpController 并将其映射到那里。我没有看到两者之间有什么不同。

这是我的 MainController.java ：

   @Controller
public class MainController {

    @RequestMapping(value = "/help", method = RequestMethod.GET)
    public String help(){
        System.out.println("GET called on help page");
        return "help.html";
    }

    @RequestMapping(value = "/main", method = RequestMethod.GET)
    public String landing(){
        System.out.println("GET called on index page");
        return "landing.html";
    }
}

我的App.java：

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class App {

//    private static final Logger logger = Logger.getLogger(App.class.toString());

    public static void main(String[] args){
        SpringApplication.run(App.class, args);
    }
}

我将两个html模板放在resources / static目录中：

但是这两个路径中只有一个能够正确解析。 main.html 看起来很棒：

但是 help.html 有一个我无法解决或理解的循环引用：

这是我的 pom.xml （隐私时省略了某些标签）：

只有第一个请求映射才能解析Java Spring Boot（循环视图路径）
