How to Website complete markup with java code ?
Creating a complete website markup with Java code would require a more extensive example, including multiple pages, handling different HTTP methods (GET, POST, etc.), and possibly interactions with a database. Since providing a fully functional complete website is beyond the scope of a single response, I'll give you a more comprehensive but still simplified example of a Java-based web application using the Spring Framework.
For this example, we'll use Spring Boot, which provides a quick way to set up a web application with minimal configuration. We'll create a simple "To-Do List" application that allows users to add and view tasks.
Step 1: Set up the project and create the necessary files and directory structure.
Step 2: Create the main class with the Spring Boot application annotation.
Step 3: Create a controller to handle user requests and manage tasks.
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import java.util.ArrayList;
import java.util.List;
@Controller
public class TaskController {
private List<String> tasks = new ArrayList<>();
@GetMapping("/")
public String index(Model model) {
model.addAttribute("tasks", tasks);
return "index";
}
@PostMapping("/add")
public String addTask(@RequestParam String task) {
tasks.add(task);
return "redirect:/";
}
}
Step 4: Create the HTML template for the "index" page (resources/templates/index.html).
<head>
<title>To-Do List</title>
</head>
<body>
<h1>To-Do List</h1>
<form action="/add" method="post">
<input type="text" name="task" required />
<input type="submit" value="Add Task" />
</form>
<ul>
<#list tasks as task>
<li>${task}</li>
</#list>
</ul>
</body>
Step 5: Add the necessary dependencies to your project's build file (e.g., Maven or Gradle) to include Spring Boot and other required libraries.
Step 6: Run the application, and it should be accessible at http://localhost:8080/. Users can add tasks through the form, and the tasks will be displayed as a list on the same page.
Keep in mind that this example is still simplified, and in a real-world scenario, you would typically use a more robust data storage solution (e.g., a database) instead of keeping tasks in-memory as we did here. Additionally, you can extend the application to include features such as task deletion, task details, user authentication, and more, depending on your requirements.
Remember to have the appropriate dependencies and configurations in your project to run the example successfully.
