java - Java Spring Boot:Servlet [dispatcherServlet]的Servlet.service()抛出异常

Question

我正在尝试编写一个Spring Boot应用程序来为AngularJS应用程序提供一个文件“ index.html”。我有以下课程：

应用程序

@SpringBootApplication
public class Application
        extends SpringBootServletInitializer
{
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
    {
        return application.sources(Application.class);
    }

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

BaseController.java

@Controller
public class BaseController
{
    // Map all urls to this method aside from ones starting with api
    @RequestMapping(value = "/**")
    public String getIndexHtml()
    {
        System.out.println("hi me");
        return "index";
    }
}

MvcConfiguration.java

@Configuration
public class MvcConfiguration
        extends WebMvcConfigurerAdapter
{
    @Bean
    public ViewResolver getViewResolver()
    {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".html");
        return resolver;
    }
}

以及以下目录结构：

src └── main     ├── java     │   └── com     │       └── myangularapp     │           ├── Application.java     │           ├── config     │           │   └── MvcConfiguration.java     │           └── controllers     │               └── BaseController.java     └── webapp         └── WEB-INF             └── index.html

I then have gradle create the application into a war before deploying on tomcat 8.

However, any time I try and visit the website, I always see this page:

And the following stack trace:

2017-07-15 00:01:51.551 ERROR 42496 --- [nio-8090-exec-1] o.a.c.c.C.[.[.[.5.0.[dispatcherServlet]  : Servlet.service() for servlet [dispatcherServlet] threw exception

at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:231) ~[servlet-api.jar:na]

最终变成：

有人知道我在做什么错吗？

在此 answer的背面，我的MvcConfiguration类上没有 @EnableWebMvc。我添加了它，视图已解决，一切都开始工作。

Answer 1

Spring Boot将自动添加位于以下任何目录中的静态Web资源：


  
  / META-INF /资源/
  /资源/
  /静态的/
  /上市/
  


您需要创建一些spring想要的目录，创建一个src/main/resources/index.html
