我应该将jsp文件放在spring-boot项目中的位置

Question

最近，我开始使用 spring-boot，我正在尝试转换我的旧 spring 项目，它们都是 Web 应用程序，以使用它。我设法编译、打包和运行应用程序，但是当我尝试在浏览器中访问它们时，我无法访问我的视图。

首先，我尝试将jsp页面放在通常的文件夹src/main/webapp/WEB-INF/jsp中，但是从官方文档中阅读了这篇文章后：

http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-spring-mvc-static-content

我尝试将它们放在文件夹 src/main/resources 中。这些都不起作用。谁能告诉我应该把这些文件放在哪里，以便在应用程序运行时可以访问它们？

我的 pom.xml 是这样的：

我有这个控制器来映射视图：

@Controller
public class AcessoController {

    @RequestMapping(value = "/signin")
    public String signin(Model model) {
        return "acesso/signin";
    }

    @RequestMapping(value = "/admin")
    public String admin(Model model) {
        return "private/admin";
    }

    @RequestMapping(value = "/index")
    public String index(Model model) {
        return "public/index";
    }

}

还有这个配置类：

WebAppConfig.java

@EnableWebMvc
@Configuration
@ComponentScan(value="com.spring.app")
public class WebAppConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

}

WebAppInitializer.java

@Order(value=1)
public class WebAppInitializer implements WebApplicationInitializer {

    @SuppressWarnings("resource")
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
          // Create the 'root' Spring application context
          AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
          rootContext.register(WebAppConfig.class);

          // Create the dispatcher servlet's Spring application context
          AnnotationConfigWebApplicationContext jspContext = new AnnotationConfigWebApplicationContext();
          jspContext.register(DispatcherConfig.class);

          // Register and map the dispatcher servlet
          ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(jspContext));
          dispatcher.setLoadOnStartup(1);
          dispatcher.addMapping("/");
    }

}

DispatcherConfig.java

@Configuration
@Import(WebAppConfig.class)
public class DispatcherConfig {

    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

}

如果使用 Jetty 或 Tomcat 作为嵌入式 servlet 容器，只需将您的包装从 jar 更改为 war，然后使用 java -jar 启动它...
