How to use the Webman framework to build a modern front-end and back-end separation application?

With the development of the Internet, the development model of front-end and back-end separation has attracted more and more attention. The separation of front-end and back-end allows front-end and front-end developers to develop in parallel, and front-end developers can also better use some modern front-end frameworks. In actual development, how to effectively use the framework to build a modern front-end and back-end separation application? This article will introduce how to use the Webman framework to build a modern front-end and back-end separation application, and illustrate it through some code examples.

Webman is a lightweight Web framework based on Java language. It is simple, flexible and easy to use. Through Webman, we can easily build interfaces and handle HTTP requests and responses.

First of all, we need to introduce the Webman framework into the project. Assuming that our project is a Maven project, we can add the following dependencies in the pom.xml file:

<dependency>
    <groupId>com.github.yueeng</groupId>
    <artifactId>webman</artifactId>
    <version>1.1.0</version>
</dependency>

Next, we can create a simple controller to handle HTTP requests. First, we need to define a class and use the @WebController annotation to define it as a controller:

@WebController
public class HelloController {
    
    @WebRoute("/hello")
    public String hello() {
        return "Hello, World!";
    }
    
}

In the above code, we define a HelloController class and define a handler in it to handle HTTP requests Method hello(). Through the @WebRoute annotation, we associate this method with the URL path /hello. When there is a request to access this path, the framework will automatically call the hello() method and return its return value to the client as an HTTP response.

Next, we need to configure the router. In the Webman framework, we can configure the router by writing a configuration class. For example, we can create a configuration class named WebConfig:

@WebConfiguration
public class WebConfig implements WebRouteConfigurer {
    
    @Override
    public void configure(WebRouter router) {
        router.addRoute("/hello", HelloController.class);
    }
    
}

In the above code, we implement the WebRouteConfigurer interface and override the configure() method. In this method, we can use the router object to add routes. In this example, we associate the path /hello with the HelloController class.

Finally, we need to start the application. The Webman framework supports embedded servers. We can start the application by writing a main class:

public class Application {

    public static void main(String[] args) {
        WebApplication.run(Application.class, args);
    }
    
}

In this main class, we use the WebApplication.run() method to start the application. We can pass the Application class as a parameter to this method to tell the framework the entry point of our application.

So far, we have completed the basic steps of using the Webman framework to build a modern front-end and back-end separation application. Through the above code examples, we can see that using the Webman framework can very conveniently build applications with separate front and back ends. We only need to define a controller to handle HTTP requests and configure the router in the configuration class.

Of course, the Webman framework has more functions and features, such as routing parameters, interceptors, filters, etc. If we need more complex functionality, we can learn more detailed usage by consulting the framework's documentation.

To summarize, this article introduces how to use the Webman framework to build a modern front-end and back-end separation application, and illustrates it through code examples. I hope that through the introduction of this article, readers will have a certain understanding of how to effectively use the Webman framework to build front-end and back-end separation applications.
