Quickly develop web applications using SpringBoot and SpringMVC
Title: Rapidly develop web applications using Spring Boot and Spring MVC
Spring Boot and Spring MVC are modern Java web development frameworks that combine simplicity, efficiency and Flexible features can help developers quickly build reliable web applications. This article will introduce how to use Spring Boot and Spring MVC to develop a simple web application and provide specific code examples.
Environment settings
Before you start, you need to ensure that the following software has been installed on your computer:
- JDK 1.8 and above
- Maven 3 .x
- IDE (such as Eclipse or IntelliJ IDEA)
Create a Spring Boot project
First, we need to create a Spring Boot project. You can easily create a basic Spring Boot project skeleton using Maven commands or the IDE's create project wizard. When creating a project, you need to add relevant dependencies and plug-ins:
<dependencies>
<!-- Spring Boot Web -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>Create a controller
Next, we need to create a controller class to handle HTTP requests and responses. In Spring MVC, controllers are used to define URL routing and methods for handling requests.
@RestController
public class HelloWorldController {
@GetMapping("/")
public String helloWorld() {
return "Hello, world!";
}
}In the above code, we use the @RestController annotation to tell Spring that this is a controller class, and use the @GetMapping annotation to define the processing/URL method.
Start the application
Now, we need to write a startup class to start our Spring Boot application.
@SpringBootApplication
public class WebApplication {
public static void main(String[] args) {
SpringApplication.run(WebApplication.class, args);
}
}In the above code, we use the @SpringBootApplication annotation to start the Spring Boot application and use the SpringApplication.run method to run the application.
Testing the Application
Now we can launch the application and test our application by visiting http://localhost:8080 in the browser. If everything is OK, you will see a simple "Hello, world!" message.
Handling form submission
In addition to handling ordinary HTTP requests, Spring MVC can also handle form submission. The example below shows how to handle a simple form submission and store the data into the database.
First, we need to create a form page form.html, including an input box and a submit button.
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Form</title>
</head>
<body>
<form action="/save" method="post">
<input type="text" name="name" placeholder="请输入姓名">
<button type="submit">提交</button>
</form>
</body>
</html>Then, we need to create a controller to handle the form submission and store the data into the database.
@Controller
public class FormController {
@Autowired
private UserRepository userRepository;
@GetMapping("/form")
public String showForm() {
return "form";
}
@PostMapping("/save")
public String saveData(@RequestParam String name) {
User user = new User();
user.setName(name);
userRepository.save(user);
return "redirect:/form";
}
}In the above code, the showForm method is used to return the form page, while the saveData method is used to handle form submission and store user data into the database . redirect:/form is used to redirect to the form page.
Summary
By using Spring Boot and Spring MVC, we can quickly develop and deploy web applications. This article gives a simple example showing how to use Spring Boot and Spring MVC to handle HTTP requests and form submissions. I hope this article was helpful and I wish you success in web development!
The above are specific code examples for using Spring Boot and Spring MVC to quickly develop web applications. Through these examples, you can quickly get started with Spring Boot and Spring MVC, and develop efficient and flexible web applications. Happy coding!
