我想寫一個Spring Boot應用程序來爲我的AngularJS應用程序提供單個文件「index.html」。我有以下類：Java Spring Boot：Servlet.service（）for servlet [dispatcherServlet]拋出異常
Application.java
@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;
}
}
而下面的目錄結構：
src
└── main
├── java
│ └── com
│ └── myangularapp
│ ├── Application.java
│ ├── config
│ │ └── MvcConfiguration.java
│ └── controllers
│ └── BaseController.java
└── webapp
└── WEB-INF
└── index.html
我再有gradle這個部署在Tomcat 8
但是之前創建的應用程序轉變成戰爭，任何時候我嘗試訪問的網站，我總是看到這個頁：
而下面的堆棧跟蹤：
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

最終變成：

有人知道我在做什麼錯嗎？

關於這個answer的背面，我的MvcConfiguration類沒有@EnableWebMvc。我添加了它，視圖已經解決，一切開始工作。
