I am creating a log in page, which will allow the user to sign in. However, when I try to visit http://localhost:8080/index via Google Chrome, I am just seeing "index," nothing else. But it is supposed to display the log in page that I created using HTML and Bootstrap.
Here are the codes of HomeController.java
package com.userFront.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HomeController {
@RequestMapping("/")
public String home() {
return "redirect:/index";
}
@RequestMapping("/index")
public @ResponseBody String index() {
return "index";
}
}
You can find all the project files here: https://drive.google.com/open?id=1fxTWDo_3_iaS4zaav60KaT9OvB-kSjv6
Update:1 I have been advised to remove @ResponseBody from the method index(). But when I do that, the following problem occurs:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
Circular view path [index]: would dispatch back to the current handler URL [/index] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)
Update 2: Here is the latest version of HomeController class, which I modify based on the advise I receive from @vtx:
package com.userFront.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/")
public String home() {
return "redirect:/index";
}
@RequestMapping("/welcome")
public String index() {
return "index";
}
}
But now, a new error occurs, which says:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

Update 3: As advised by @vtx, I have tried to clean install Maven. However, the following error occurs:

Update 4: As suggested by @vtx, I have performed clean installation of Maven.
I have followed stackoverflow.com/questions/19655184/… and stackoverflow.com/questions/19655184/…. Maven is installed cleanly without any error. But now, I am getting "Circular view path" error.
Update 5: @vtx suggested me to use the following code again:
package com.userFront.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/")
public String home() {
return "redirect:/index";
}
@RequestMapping("/welcome")
public String index() {
return "index";
}
}
But once again, I am getting the following error:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

It's getting incredibly frustrating. But I will not give up!
