vertx实践二——基于EventBus的交互demo

1.代码展示

第一个vertx服务启动类

package org.example;

import com.hazelcast.config.Config;
import com.hazelcast.config.FileSystemXmlConfig;
import io.vertx.core.Vertx;
import io.vertx.core.VertxOptions;
import io.vertx.core.eventbus.EventBusOptions;
import io.vertx.spi.cluster.hazelcast.HazelcastClusterManager;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class AppCluster {

    public static void main(String[] args) throws  UnknownHostException {
        final VertxOptions vertxOptions = new VertxOptions();
        EventBusOptions eventBusOptions = new EventBusOptions();
        // 本机局域网Ip
        String hostAddress = InetAddress.getLocalHost().getHostAddress();
        vertxOptions.setEventBusOptions(eventBusOptions).getEventBusOptions().setHost(hostAddress);

        HazelcastClusterManager clusterManager = new HazelcastClusterManager();

        vertxOptions.setClusterManager(clusterManager);

        Vertx.clusteredVertx(vertxOptions, res -> {
            Vertx result = res.result();
            result.deployVerticle(new MainClusterVerticle(), r -> {
                if (r.succeeded()) {
                    System.out.println(MainClusterVerticle.class.getName() + " --> 部署成功");
                } else {
                    r.cause().printStackTrace();
                    System.err.println(MainClusterVerticle.class.getName() + " --> 部署失败, " + r.cause().getMessage());
                }
            });
        });
    }
}

第一个vertx服务verticle

package org.example;

import io.vertx.core.AbstractVerticle;
import io.vertx.core.http.HttpServer;
import io.vertx.core.json.JsonObject;
import io.vertx.ext.web.Router;

public class MainClusterVerticle extends AbstractVerticle {

  public void start() {
    System.out.println("start thread" + Thread.currentThread().getName());
    //发布eventbus服务
    vertx.eventBus().consumer("com.xiaoniu.bus", msg -> {
      System.out.println("read thread" + Thread.currentThread().getName());
      System.out.println("收到消息");
      System.out.println(msg != null ? ((JsonObject) msg.body()).encodePrettily() : "没有消息");
      JsonObject j = new JsonObject();
      j.put("info", "我是Main");
      msg.reply(j);
    });
    //发布web服务

    // 创建HttpServer
    HttpServer server = vertx.createHttpServer();
    // 创建路由对象
    Router router = Router.router(vertx);

    // 监听/index地址
    router.route("/index").handler(request -> {
      request.response().end("INDEX SUCCESS");
    });

    // 监听/index地址
    router.route("/index1").handler(request -> {
      request.response().end("INDEX1 SUCCESS");
    });
    // 把请求交给路由处理--------------------(1)
    server.requestHandler(router);
    server.listen(8888);
  }
}

第二个vertx服务启动类

package org.example;

import com.hazelcast.config.Config;
import com.hazelcast.config.FileSystemXmlConfig;
import io.vertx.core.Vertx;
import io.vertx.core.VertxOptions;
import io.vertx.core.eventbus.EventBusOptions;
import io.vertx.spi.cluster.hazelcast.HazelcastClusterManager;

import java.io.FileNotFoundException;
import java.net.InetAddress;
import java.net.UnknownHostException;

/**

 */
public class AppCluster2 {

    public static void main(String[] args) throws  UnknownHostException {
        final VertxOptions vertxOptions = new VertxOptions();
        EventBusOptions eventBusOptions = new EventBusOptions();
        // 本机Ip
        String hostAddress = InetAddress.getLocalHost().getHostAddress();
        vertxOptions.setEventBusOptions(eventBusOptions).getEventBusOptions().setHost(hostAddress);

        HazelcastClusterManager clusterManager = new HazelcastClusterManager();

        vertxOptions.setClusterManager(clusterManager);
        Vertx.clusteredVertx(vertxOptions, res -> {
            Vertx result = res.result();
            result.deployVerticle(new MainClusterVerticle2(), r -> {
                if (r.succeeded()) {
                    System.out.println(MainClusterVerticle2.class.getName() + " --> 部署成功");
                } else {
                    r.cause().printStackTrace();
                    System.err.println(MainClusterVerticle2.class.getName() + " --> 部署失败, " + r.cause().getMessage());
                }
            });
        });
    }
}

第二个vertx服务verticle

package org.example;

import io.vertx.core.AbstractVerticle;
import io.vertx.core.http.HttpServer;
import io.vertx.core.json.JsonObject;
import io.vertx.ext.web.Router;

public class MainClusterVerticle2 extends AbstractVerticle {
  public void start() {
    System.out.println("start thread" + Thread.currentThread().getName());
    //发布web服务

    // 创建HttpServer
    HttpServer server = vertx.createHttpServer();
    // 创建路由对象
    Router router = Router.router(vertx);
    // 监听/index地址
    router.route("/index").handler(request -> {
      System.out.println("haha" + Thread.currentThread().getName());
      System.out.println("时间到了，发送消息");
      JsonObject json = new JsonObject().put("info", "我是另主");
      System.out.println("send thread" + Thread.currentThread().getName());
      //通过eventbus发送请求
      vertx.eventBus().request("com.xiaoniu.bus", json, msg -> {
        System.out.println("read thread" + Thread.currentThread().getName());
        if (msg.succeeded()) {
          System.out.println(msg.result() != null
                  ? ((JsonObject)msg.result().body()).encodePrettily()
                  : "没有信息");
        } else {
          System.err.println(msg.cause().getMessage());
          msg.cause().printStackTrace();
        }
      });
      request.response().end("INDEX SUCCESS");
    });

    // 把请求交给路由处理--------------------(1)
    server.requestHandler(router);
    server.listen(7777);


  }
