进入idea，新建一个maven项目
主要是模拟150个设备同时并发，并发时间持续15min
1.创建客户端，构造请求发送到对应的rabbitmq的队列，用的protobuf协议。
import com.google.protobuf.ByteString; import com.rabbitmq.client.*; import org.apache.commons.codec.DecoderException; import org.apache.commons.codec.binary.Hex; import java.io.IOException; import java.text.SimpleDateFormat; import java.util.Date; import java.util.concurrent.TimeoutException; public class Producer { //上传的命令字段值参数化 private final static String[] COMMANDS = new String[]{ "XXXXX", "YYYYYY" "ZZZZZ", }; private int index; public Producer(int index) { this.index = index; } public byte[] message(byte[] command) { //根据proto文本消息生成的slot3编辑脚本，构建一个消息 Slot3.SlotMessage.Builder slots = Slot3.SlotMessage.newBuilder(); slots.setOpenId("XXX"); slots.setProductId("YYYY"); //长整型 String NO = String.valueOf(70000000000l + index); slots.setNodeEui(NO); slots.setCommand(Slot3.SlotMessage.Command.DOWNLINK); SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date date = new Date(); String time1 = f.format(date); slots.setTimestamp(time1); Slot3.SlotMessage.Payload.Builder payload = Slot3.SlotMessage.Payload.newBuilder(); ByteString command2 = ByteString.copyFrom(command); payload.setData(command2); slots.addPayload(payload); slots.setAppMessageType(0); Slot3.SlotMessage msg = slots.build(); System.out.println("before:" + msg); System.out.println("===msg Byte:"); byte[] msgbyteArray = msg.toByteArray(); System.out.println(msgbyteArray); return msgbyteArray; } /** * 构造函数 * RabbitMQ客户端相关配置 * 连接AMQP broker并初始化队列 */ public void produce() throws IOException, TimeoutException { ConnectionFactory factory = new ConnectionFactory(); //设置RabbitMQ相关信息 factory.setHost("10.10.XX.XX"); factory.setPort(5671); factory.setUsername("rabbitmq用户名"); factory.setPassword("rabbitmq密码"); factory.setVirtualHost("/"); //创建发送消息rabbitmq信息的连接 Connection connection = factory.newConnection(); Channel channel = connection.createChannel(); String exchange = "交互机名称"; String queue = "队列名称"; for (String input : COMMANDS) { byte[] body = message(decodeHex(input)); channel.basicPublish(exchange, queue, null, body); try { //生成0~1秒的随机 // Double code = (Math.random() * 9 + 1) * 100; // Long ms =code.longValue(); //每个命令请求间隔1s Thread.sleep(1000l); } catch (Exception e) { e.printStackTrace(); } } channel.close(); connection.close(); } /** * Hex解码. */ public static byte[] decodeHex(String input) { try { return Hex.decodeHex(input.toCharArray()); } catch (DecoderException e) { throw new RuntimeException(e); } } }
2.模拟150个设备同时并发，发送消息
1 public class ConsumerClient { 2 3 public static void main(String[] args) throws Exception { 4 //并发150次 5 for (int i = 0; i < 150; i++) { 6 final int index = i; 7 new Thread(() -> { 8 //创建producer 9 Producer producer = new Producer(index); 10 Long start = System.currentTimeMillis(); 11 12 while (true) { 13 try { 14 //发送消息 15 producer.produce(); 16 } catch (Exception e) { 17 e.printStackTrace(); 18 } 19 //持续运行15分钟 20 Long end = System.currentTimeMillis(); 21 if (end - start >= 15 * 60 * 1000l) { 22 break; 23 } 24 } 25 26 }).start(); 27 28 } 29 } 30 }
3.pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>Commandxingneng</groupId> <artifactId>Commandxingneng</artifactId> <version>1.0-SNAPSHOT</version> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.26</version> <scope>test</scope> </dependency> <dependency> <groupId>com.rabbitmq</groupId> <artifactId>amqp-client</artifactId> <version>3.6.5</version> </dependency> <dependency> <groupId>com.google.protobuf</groupId> <artifactId>protobuf-java</artifactId> <version>3.6.1</version> </dependency> <dependency> <groupId>io.vertx</groupId> <artifactId>vertx-core</artifactId> <version>RELEASE</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>RELEASE</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>RELEASE</version> </dependency> </dependencies> </project>
4.运行ConsumerClient.java就好了
5.proto3文本内容，怎么生成编辑脚本，参考python模拟上报消息到rabbitMQ（protobuf） ，java一样
syntax = "proto3";
message SlotMessage
{
string openId = 1;
string productId = 2;
string nodeEui = 3;
Command command = 4;
string timestamp = 5;
bool encrypted = 6;
repeated Payload payload = 7;
int32 appMessageType = 8;
enum Command {
U = 0;
D = 1;
C = 2;
O_RESULT = 3;
}
message Payload {
bytes data = 1;
Connect connect = 2;
repeated OResult oResult = 3;
enum Connect{
OFF = 0;
ON = 1;
HE = 2;
}
message OResult {
string d = 1;
int32 r = 2;
string s = 3;
}
}
}
