Spring Boot - Request Mapping won't accept trailing slash or multiple directories

When RequestMapping in my controller, I'm able to map an html file to "/" and another to "/users". However, trying to map to "/users/" or "/users/test" won't work. In the console it'll say that the endpoint was mapped, but on trying to access it I'll get the 404 error page.

package com.bridge.Bitter.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class BitterController {

//works
@RequestMapping(value="/")
public String getMainPage(){
return "main.html";
}

//works
@RequestMapping(value="/users")
public String getUsersPage(){
return "users.html";
}

//doesn't work, Whitelabel error page
@RequestMapping(value="/users/")
public String getUsersSlashPage(){
return "users.html";
}
//doesn't work, Whitelabel error page
@RequestMapping(value="/users/test")
public String getUsersTestPage(){
return "users.html";
}

}


My application.properties only contains "spring.data.rest.basePath=/api".

If I change from @Controller to @Rest Controller, The following occurs:

package com.bridge.Bitter.controllers;

import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;

@RestController
public class BitterController {

//works
@RequestMapping(value="/")
public String getMainPage(){
return "main.html";
}

//returns a webpage with the text "users.html" on it instead of serving the html
@RequestMapping(value="/users")
public String getUsersPage(){
return "users.html";
}

//returns a webpage with the text "users.html" on it instead of serving the html
@RequestMapping(value="/users/")
public String getUsersSlashPage(){
return "users.html";
}
//returns a webpage with the text "users.html" on it instead of serving the html
@RequestMapping(value="/users/test")
public String getUsersTestPage(){
return "users.html";
}

}


Changing the functions from returning strings to returning

new ModelAndView("user.html")


works for /users but will then 404 error for /users/ and /users/test.

You're trying to map the same path twice. /users is treated the same as /users/, so Spring can not resolve which controller method should handle the request.

You can just try this:

package com.bridge.Bitter.controllers;

import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class BitterController {

@RequestMapping("/")
public String getMainPage(){
return "main.html";
}

@RequestMapping("/users")
public String getUsersPage(){
return "users.html";
}

@RequestMapping("/users/test")
public String getUsersTestPage(){
return "users.html";
}
}


In the other hand, when you use @RestController annotation, you always return a response text in JSON format, that's why you always get the same result.
