login.jsp contains just hello

LoginController.class

@Controller
public class LoginController {
@RequestMapping(value = {"/","/login"},method = RequestMethod.GET)
public ModelAndView getLoginPage(){
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("login");
    return modelAndView;
    }
}

WcApplication.class

@SpringBootApplication
public class WcApplication {

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

Why I'm getting this and how to solve this problem? Thanks

Answer 1

I faced the same issue and it took me long time to figure out that there are three conditions.

1.) In application properties you need to have the following view resolver mapping (You can use java based as well):

logging.level.web=DEBUG
spring.mvc.view.prefix=/WEB-INF/pages/
spring.mvc.view.suffix=.jsp

Note: you have to create "WEB-INF" folder by yourself as in my case "webapp" 
   folder was empty. DEBUG property is not necessary just keep it as it will 
   help you find the root cause from logs. 

2.) I had to make the packaging as "war" instead of jar.

<packaging>war</packaging>

3.) Make sure you have added tomcat jasper dependency to compile the jsp pages at runtime.

    <dependency>
      <groupId>org.apache.tomcat.embed</groupId>
      <artifactId>tomcat-embed-jasper</artifactId>
    </dependency>

Hope it helps and feel free to correct me.
