The JVM SDK currently only supports legacy versions of Nitric prior to v1. This version is maintained for compatibility with existing projects and not recommended for new projects. New projects should be started using a supported SDK (presented automatically using the `nitric new` command) orget in touch to request an update to the latest version.

JVM - api.route.get()

import io.nitric.Nitric;

class User {
  String name;
  int age;

  public User(String name, int age) {
    this.name = name;
    this.age = age;
  }
}

public class Application {
  public static void main(String[] args) {
    var api = Nitric.INSTANCE.api("public");

    api.route("/customers").get((ctx) -> {
      // construct response for the GET: /customers request...
      ctx.getResp().json(User("John Smith", 31));
      return ctx;
    });

    Nitric.INSTANCE.run();
  }
}

Parameters

Name
middleware
Required
Required
Type
HttpMiddleware or List<HttpMiddleware>
Description
One or more middleware functions to use as the handler for HTTP requests. Handlers can be sync or async

Examples

Register a handler for GET requests

import io.nitric.Nitric;

class User {
  String name;
  int age;

  public User(String name, int age) {
    this.name = name;
    this.age = age;
  }
}

public class Application {
  public static void main(String[] args) {
    var api = Nitric.INSTANCE.api("public");

    api.route("/customers").get((ctx) -> {
      // construct response for the GET: /customers request...
      ctx.getResp().json(User("John Smith", 31));
      return ctx;
    });

    Nitric.INSTANCE.run();
  }
}

Chain functions as a single method handler

When multiple functions are provided they will be called as a chain. If one succeeds, it will move on to the next. This allows middleware to be composed into more complex handlers.

import io.nitric.Nitric;
import io.nitric.faas.v0.HttpContext;
import io.nitric.faas.v0.Handler;

import java.util.List;

public class Application {
  static HttpContext validateRequest(HttpContext ctx, Handler<HttpContext> next) {
    // validateRequest
    return next.invoke(ctx);
  }

  static HttpContext handleRequest(HttpContext ctx, Handler<HttpContext> next) {
    // handle request
    return next.invoke(ctx);
  }

  public static void main(String[] args) {
    var api = Nitric.INSTANCE.api("public");

    api.route("/customer").get(List.of(Application::validateRequest, Application::handleRequest));

    Nitric.INSTANCE.run();
  }
}
