Here are instructions on how you can get started with MySQL in Metronic SpringBoot starterkit.

1. Install MySQL on your machine.
2. You can use the default root and no password user to login to your MySQL console by running mysql -u root -p
3. Login to MySQL console and create your database and tables.
4. In file src/main/resources/application.properties add database properties.
   
   
   copy

   spring.datasource.url=jdbc:mysql://localhost:3306/db-name
   spring.datasource.username=your-user-name
   spring.datasource.password=your-passowrd
   spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
   </pre
   >
   Make sure to change db-name with your database name and update your username and password.</li>
   <li>Add dependencies below to <strong>starterkit/pom.xml</strong>.
   <pre lang="xml">
   <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

   
   
5. Execute mvn clean install.
6. This is all configuration you need to do to get started with database.
7. Now you can add your entity, repository, and controller classes to display your database data in markup.
   
   Entity examples:
   
   
   copy

   package com.theme.starterkit.models;
   
   import javax.persistence.Entity;
   import javax.persistence.GeneratedValue;
   import javax.persistence.GenerationType;
   import javax.persistence.Id;
   
   @Entity
   public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public Long id;
   
    public String first_name;
    public String last_name;
   }

   
   
   Repository example:
   
   
   copy

   package com.theme.starterkit.repository;
   
   import com.theme.starterkit.models.User;
   import org.springframework.data.jpa.repository.JpaRepository;
   import org.springframework.stereotype.Repository;
   
   @Repository
   public interface UsersRepository extends JpaRepository<User, Long> {
    User findById(long id);
   }
   Controller example.
   package com.theme.starterkit.controller;
   
   import com.theme.starterkit.repository.UsersRepository;
   import com.theme.starterkit.models.Users;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.stereotype.Controller;
   import org.springframework.web.bind.annotation.GetMapping;
   import org.springframework.ui.Model;
   import org.springframework.web.bind.annotation.PathVariable;
   
   import com.theme.starterkit.libs.KTTheme;
   import com.theme.starterkit.libs.config.KTThemeBaseConfig;
   
   @Controller
   public class UserController {
    @Autowired
    private KTTheme theme;
   
    @Autowired
    private UserRepository userRepository;
   
    @GetMapping("/user/{id}")
    public String getUserById(@PathVariable long id, Model model) {
    User user = usersRepository.findById(id);
    model.addAttribute("user", user);
    return theme.getPageView("user", "user-details");
    }
   }

   
   
   Then you can add user-detail.html inside resources/templates/pages/user with the following code.
   
   
   copy

   <div layout:fragment="content">
    <h1>User Details</h1>
    <div th:if="${user}">
    <p>User ID: <span th:text="${user.id}" /></p>
    <p>Name: <span th:text="${user.first_name}" /></p>
    <p>Email: <span th:text="${user.last_name}" /></p>
    </div>
    <div th:unless="${user}">
    <p>User not found</p>
    </div>
   </div>
