當部署到生產時，Springboot應用程序網頁返回404

Question

我有一個springboot應用程序，在本地運行時爲網頁提供服務，但由於某種原因返回404時，我將部署war文件打包爲生產環境，出現404錯誤。在我的控制器中，我返回一個包含來自我的/ resources/static文件夾的html頁面的jsp頁面。這一切都在當地正常工作。

我部署到tomcat的7.0.52

這是我的聚甲醛

我Springboot應用程序的主類

@SpringBootApplication 
public class SpringbootApplication extends SpringBootServletInitializer { 

@Override 
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
    return application.sources(SpringbootApplication.class); 
} 

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

我的類擴展webmvcConfigureAdapter

@Configuration 
@EnableWebMvc 
public class MvcConfiguration extends WebMvcConfigurerAdapter{ 

@Override 
public void addViewControllers(ViewControllerRegistry registry) { 
    System.out.println("in mvc config"); 
    registry.addViewController("/").setViewName("forward:index2.html"); 
} 

@Override 
public void configureDefaultServletHandling(
     DefaultServletHandlerConfigurer configurer) { 
    System.out.println("configure serve handling"); 
    configurer.enable(); 
} 

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

我的主控制器。

@Controller 
public class MainController { 
    @RequestMapping(value={"/"}, method = RequestMethod.GET) 
    public String index(){ 
     System.out.println("inside mainController"); 
     return "chatbot"; 
    } 
} 

最後我的application.properties文件看起來像這樣。

spring.mvc.view.prefix: /WEB-INF/jsp/ 
spring.mvc.view.suffix: .jsp 

我的項目結構看起來像這樣...

src/main/webapp 
       -> assets 
       -> resources 
        -> static ->index.html 
       -> WEB-INF  
        ->jsp -> index.jsp 

請幫助。我一直堅持8小時以上。 謝謝。

Answer 1

您可以將您的index.html下的web應用，因爲這是默認的contextPath，所有其他資源應該是相關的。

Answer 2

也許問題是你必須包含應用程序上下文路徑。
