using spring boot and java 17, what is the simplest way to create a basic web application, with a main page where I enter a search parameter and, with a click of a button, I execute a Java function and return a result web page?

Creating a basic web application with Spring Boot and Java 17 that includes a main page with a search function is quite straightforward. Here's a simple guide on how to set it up:
1. Set Up Your Project

    Use Spring Initializr: Go to Spring Initializr to generate a basic Spring Boot project. Choose Maven/Gradle as your build tool, Java as the language, and specify Java 17 as the version.
    Dependencies: Add spring-boot-starter-web for web application development.
    Generate and Open: Generate the project and open it in your preferred IDE (like IntelliJ IDEA or Eclipse).

2. Create a Controller Class

    Controller Class: Create a new Java class annotated with @Controller. This class will handle web requests.

    java

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.ui.Model;

    @Controller
    public class MyController {

        @GetMapping("/")
        public String home() {
            return "index"; // points to index.html
        }

        @PostMapping("/search")
        public String search(@RequestParam String query, Model model) {
            // Process the search here
            String result = processSearch(query);
            model.addAttribute("result", result);
            return "result"; // points to result.html
        }

        private String processSearch(String query) {
            // Implement your search logic here
            return "Result for: " + query;
        }
    }

3. Create HTML Pages

    Index Page (index.html): In src/main/resources/templates, create index.html with a form for input.

    html

<!DOCTYPE html>
<html>
<head>
    <title>Home</title>
</head>
<body>
    <form action="/search" method="post">
        <input type="text" name="query">
        <button type="submit">Search</button>
    </form>
</body>
</html>

Result Page (result.html): Create result.html to display the search results.

html

    <!DOCTYPE html>
    <html>
    <head>
        <title>Search Result</title>
    </head>
    <body>
        <p>Search result: ${result}</p>
    </body>
    </html>

4. Run Your Application

    Run your Spring Boot application from the IDE or using the command line (mvn spring-boot:run for Maven or gradle bootRun for Gradle).
    Access http://localhost:8080 in your web browser.

5. Optional Enhancements

    Add Error Handling: Implement error handling for your search function.
    Styling: Use CSS to style your HTML pages.
    Logging: Add logging for debugging and monitoring.
    Advanced Search Logic: Enhance the processSearch method to perform more complex searches.

This setup gives you a basic web application where you can enter a search parameter on the main page, submit it, execute a Java function, and display the result on a new page.
