Springboot 应用程序网页在部署到生产环境时返回 404

Question

>我有一个 springboot 应用程序，在本地运行时可以很好地提供网页，但由于某种原因，当我将战争文件部署到生产环境时返回 404，我收到 404 错误。在我的控制器中，我返回一个 jsp 页面，其中包含来自我的/resources/static 文件夹的 html 页面。这一切都在当地工作正常。

我正在部署到雄猫 7.0.52

这是我的诗歌

我的 Springboot 应用的主类

@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);
}
}

我的扩展webmvcConfigureAdapter 的类

@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";
}
}

最后，我的应用程序属性文件看起来像这样。

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

我的项目结构看起来像这样...

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

请帮忙。我已经坚持了 8 个多小时了。 谢谢。

Answer 1

您可以将索引.html放在 webapp 下，因为这是默认的上下文路径，所有其他资源都应该与之相关。

Answer 2

也许问题是您必须包含应用程序上下文路径。
