The main idea is to start a loginpage using Thymeleaf and i want to connect it to a database in my case mysql.When Im trying to boot start the project i get an error concerning the index.html file.The app normally starts fine but when i try to access the localhost:8080 it crashes.
this is how my index.html looks like
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="ISO-8859-1">
<title>Welcome to CodeJava Home</title>
<link rel="stylesheet" type="text/css" href="/webjars/bootstrap/css/bootstrap.min.css" />
<script type="text/javascript" src="/webjars/jquery/jquery.min.js"></script>
<script type="text/javascript" src="/webjars/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container text-center">
<h1>Welcome to CodeJava.net</h1>
<h3><a th:href="/@{/users}">List of Users</a></h3>
<h3><a th:href="/@{/register}">Register</a></h3>
<h3><a th:href="/@{/login}">Login</a></h3>
</div>
</body>
</html>
this is my user class
@Entity
@Table(name = "users")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(nullable = false, unique = true, length = 45)
private String email;
@Column(nullable = false, length = 64)
private String password;
@Column(name = "first_name", nullable = false, length = 20)
private String firstName;
@Column(name = "last_name", nullable = false, length = 20)
private String lastName;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
and my userRepo
import org.springframework.data.jpa.repository.JpaRepository;
public interface UserRepository extends JpaRepository<User, Long> {
}
this is the controller
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class AppController {
@Autowired
private UserRepository userRepo;
@GetMapping("")
public String viewHomePage() {
return "index";
}
}
this is the console log
