Hi I'm building a skeleton of a car renting webapp and I'm trying to create a view that shows some details like location name, car name etc.
View code- car-list.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>Vehicle List</title>
<h2 th:text="${location1}">Locations</h2>
<table >
<thead>
<td th:text="${vehicle1Name}">Vehicle Name</td>
</tr>
</thead>
<td th:text="${vehicle2Name}">Vehicle Name</td>
</tr>
</table>
</head>
<body>
</body>
</html>
And heres my controller
package com.project.CS4125.controller;
import com.project.CS4125.model.*;
import com.project.CS4125.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.ArrayList;
import java.util.List;
@Controller
@RequestMapping("/car-list")
public class VehicleController {
@GetMapping("/car-list")
public String carList(Model model){
Vehicle VWGolf = new BasicCar();
Vehicle Duster = new SUVDecorator(new BasicCar());
Location limerick= new Location("Limerick");
model.addAttribute("location1", limerick.getLocationName());
model.addAttribute("vehicle1Name", "Volkswagen Golf");
model.addAttribute("vehicle2Name", "Dacia Duster");
return "index";
}
}
My problem is the view comes up completely empty, any help appreciated.
EDIT Before this page I have a register and login page
index.html (register page
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>Register</title>
</head>
<body>
<form action="#" th:action="@{/register}" th:object="${user}"
method="post">
<p>User Name <input type="text" name="name"></p>
<p>Password <input type="password" name="password"></p>
<button type="submit">Register</button>
</form>
<button><a href="/login">Login Here</a></button>
</body>
</html>
login.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
<meta charset="UTF-8">
<title>Login</title>
</head>
<body>
<form action="#" th:action="@{/login}" th:object="${user}"
method="post">
<p>User Name <input type="text" name="name"></p>
<p>Password <input type="password" name="password"></p>
<button type="submit">Login</button>
</form>
<button><a href="/">Register Here</a></button>
</body>
</html>
And heres the controller for these
@Controller
@RequestMapping("/")
public class IndexController {
@Autowired
private UserService userService;
@Autowired
private CustomerFactory userFactory;
@PostMapping("/register")
public String registerUser(@ModelAttribute User user){
User u = userFactory.createUser(user.getName(), user.getPassword());
userService.saveUser(u);
return "login";
}
@GetMapping("/login")
public String login(){
return "login";
}
@PostMapping("/login")
public String loginUser(@ModelAttribute User user){
User authenticatedUser = userService.authenticate(user.getName(), user.getPassword());
System.out.println(authenticatedUser.toString());
return "car-list";
}
}
Even after adding the code from the answer below I'm still getting an empty page, after submitting the login form moving to the car list page its still empty.
I also noticed in the answer the URL is http://localhost:8080/car-list but when I try it its http://localhost:8080/login
CodePudding user response：
I've just tested your code and you have two problems.
The first one is at your:
@Controller
@RequestMapping("/car-list")
public class VehicleController {
@GetMapping("/car-list")
In this GetMapping you're saying that you want to access your template at /car-list/car-list.
The seccond one is with your template name. You're returning "index" when you should return "car-list", at this you're returning the template name.
So, editting your code like this:
@Controller
@RequestMapping("/car-list")
public class VehicleController {
@GetMapping
public String carList(Model model){
model.addAttribute("location1", "Answer");
model.addAttribute("vehicle1Name", "Volkswagen Golf");
model.addAttribute("vehicle2Name", "Dacia Duster");
return "car-list";
}
}
