java - JSP Spring Boot 在从 IntelliJ 运行时工作，但在运行 WAR 时为空页面

问题描述

我的 Spring Boot 应用程序有问题：从 IntelliJ 或使用mvn clean spring-boot:run. 但是，当我将它与它打包时，man package它会提供一个忽略我的 jsps 的空白页面。

我正在包装战争。我打算用嵌入式 tomcat 运行这个项目

我的主要课程：

@SpringBootApplication
public class SomeWebsiteApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SomeWebsiteApplication.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(SomeWebsiteApplication.class, args);
    }

}

控制器：

    @GetMapping({"/", "/hello"})
    public String hello(final Model model,
                        @RequestParam(value="name",
                                required=false,
                                defaultValue="World") final String name) {
        model.addAttribute("name", name);
        log.info("called a home page");
        return "index";
    }
}

我的jsp（位于src/main/webapp/WEB-INF/jsp/index.jsp）：

<!DOCTYPE html>
<html class="no-js" lang="en">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="x-ua-compatible" content="ie=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>Hello ${name}!</title>
        <meta class="foundation-mq">
        <link rel="stylesheet" href="css/app.css">
    </head>
    <body>
        <div class="pageWithoutFooter">
            <jsp:include page="NavigationElements/topNavigation.jsp"/>
            <h2 class="hello-title">Hello ${name}!</h2>
            <input type="button" value="Hi there!">
        </div>
        <jsp:include page="NavigationElements/footerNavigation.jsp"/>
    </body>
</html>

网络配置：

@ComponentScan
public class WebConfig implements WebMvcConfigurer {

    @Bean
    public InternalResourceViewResolver getInternalResourceViewResolver(){
        final InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/jsp/");
        resolver.setSuffix(".jsp");

        return resolver;
    }

我花了几个小时试图找到解决方案但无济于事
