# 🛣️ Server Router
|
|
|
|
In this section, we discuss how to use the `FlashServer` router to manage our `RequestHandler` instances.
|
|
The router is used to define route endpoints and their corresponding handler, which are executed when a request is made to the server.
|
|
|
|
The `FlashServer` router is an instance of the `RouteController` class, each server instance has its own router instance.
|
|
To access the router instance, you can call the `route()` method on the `FlashServer` instance.
|
|
|
|
## Creating a Route
|
|
|
|
To create a route, you need to call the `route()` method on your server's instance
|
|
and specify the base path of the route, followed by your handler class,
|
|
|
|
```java{6}
|
|
// Example.java
|
|
public class Example {
|
|
public static void main(String[] args) {
|
|
FlashServer server = new FlashServer(8080);
|
|
|
|
server.route("/api")
|
|
.register(MyHandler.class);
|
|
|
|
server.start();
|
|
}
|
|
}
|
|
```
|
|
|
|
```java{3}
|
|
// MyHandler.java
|
|
|
|
@RouteInfo(endpoint = "/hello", method = HttpMethod.GET)
|
|
public class MyHandler extends RequestHandler {
|
|
public MyHandler(Request req, Response res) {
|
|
super(req, res);
|
|
}
|
|
|
|
@Override
|
|
public Object handle() {
|
|
String response = "Hello, world!";
|
|
return response;
|
|
}
|
|
}
|
|
```
|
|
|
|
In the example above, we create an `/api` router and register the `MyHandler` class to handle requests on the `/api/hello` endpoint.
|
|
|
|
This is because the `path` property of the `RouteInfo` annotation is relative to the base path of the router, which in this case is `/api`.
|
|
|
|
Visiting `/api/hello` from your browser will result in the response `Hello, world!`. |
