Getting “404 - Not found” error with Wildfly and springboot

问题

Hello i am trying to learn wildfly and springboot with a very simple application using eclipse. The project name is springboot-test. All the classes including the main method class are in the same package.

Main method class is called 'App' which has the following code:

 @SpringBootApplication
 @RestController
 public class App {

    @Autowired
    private Student student;

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

    @RequestMapping("/index")
    public String sayHello()
    {
        return "hello from spring boot" + this.student.showAddress();
    }
}

Here are the server logs:

11:36:57,281 INFO [org.wildfly.extension.undertow] (ServerService Thread Pool -- 68) WFLYUT0021: Registered web context: '/springboot-test-0.0.1-SNAPSHOT' for server 'default-server'

Since you are using wildfly for deployment , I'm hoping you are generating war file and server logs seems to support my statement

Do you have SpringBootServletInitializer class ??? if not that's the issue

You need something like this

@SpringBootApplication
@RestController
public class ServletInitializer extends SpringBootServletInitializer{

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

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

@Override
public void onStartup(ServletContext servletContext) throws ServletException{
    super.onStartup(servletContext);

     }
@RequestMapping("/index")
public String sayHello(){
        return "hello from spring boot" + this.student.showAddress();
    }
}

I' not sure is there any issue in annotating @SpringBootApplicationand @RestController in one class. But my suggestion is to keep it separate for maintenance

@RestController
public class Mycontroller{

  @RequestMapping("/index")
  public String sayHello(){
      return "hello from spring boot" + this.student.showAddress();
  }
}

Your Server log says:

11:36:57,281 INFO [org.wildfly.extension.undertow] (ServerService Thread Pool -- 68) WFLYUT0021: Registered web context: '/springboot-test-0.0.1-SNAPSHOT' for server 'default-server'

It should be accessible at: http://localhost:8080/springboot-test-0.0.1-SNAPSHOT/index

Configure your Maven file to use <finalName>${project.artifactId}</finalName> if you like to register your address.
