solace: producer和consumer入门

一、添加依赖

<?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>org.example</groupId>
    <artifactId>mysolace</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
    </properties>
    <dependencies>
        <dependency>
            <groupId>com.solace</groupId>
            <artifactId>solace-messaging-client</artifactId>
            <version>1.1.0</version>
        </dependency>
    </dependencies>

</project>

二、生产者

package cn.edu.tju;

import com.solace.messaging.MessagingService;
import com.solace.messaging.config.SolaceProperties;
import com.solace.messaging.config.profile.ConfigurationProfile;
import com.solace.messaging.publisher.DirectMessagePublisher;
import com.solace.messaging.publisher.OutboundMessage;
import com.solace.messaging.publisher.OutboundMessageBuilder;
import com.solace.messaging.receiver.DirectMessageReceiver;
import com.solace.messaging.receiver.MessageReceiver;
import com.solace.messaging.resources.Topic;
import com.solace.messaging.resources.TopicSubscription;

import java.util.Properties;

public class SolaceProducer {
    public static void main(String[] args) {
        final Properties properties = new Properties();
        properties.setProperty(SolaceProperties.TransportLayerProperties.HOST, "xx.xx.xx.xx:55555");          // host:port
        properties.setProperty(SolaceProperties.ServiceProperties.VPN_NAME,  "default");     // message-vpn
        properties.setProperty(SolaceProperties.AuthenticationProperties.SCHEME_BASIC_USER_NAME, "admin");
        properties.setProperty(SolaceProperties.AuthenticationProperties.SCHEME_BASIC_PASSWORD, "admin");  // client-password
        properties.setProperty(SolaceProperties.ServiceProperties.RECEIVER_DIRECT_SUBSCRIPTION_REAPPLY, "true");  // subscribe Direct subs after reconnect

        final MessagingService messagingService = MessagingService.builder(ConfigurationProfile.V1)
                .fromProperties(properties).build().connect();  // blocking connect to t

        final DirectMessagePublisher publisher = messagingService.createDirectMessagePublisherBuilder()
                .onBackPressureWait(1).build().start();

        OutboundMessageBuilder messageBuilder = messagingService.messageBuilder();
        while (true) {
            try {
                Thread.sleep(5000);  // take a pause
                OutboundMessage message = messageBuilder.build(("Hello World!"));
                String topicString =  "hello";
                System.out.printf(">> Calling send() on %s%n",topicString);
                publisher.publish(message, Topic.of(topicString));
            } catch (RuntimeException e) {
                System.out.printf("### Exception caught during producer.send(): %s%n",e);

            } catch (InterruptedException e) {
                // Thread.sleep() interrupted... probably getting shut down
            }
        }
    }
}

三、消费者

package cn.edu.tju;

import com.solace.messaging.MessagingService;
import com.solace.messaging.config.SolaceProperties;
import com.solace.messaging.config.profile.ConfigurationProfile;
import com.solace.messaging.publisher.DirectMessagePublisher;
import com.solace.messaging.publisher.OutboundMessage;
import com.solace.messaging.publisher.OutboundMessageBuilder;
import com.solace.messaging.receiver.DirectMessageReceiver;
import com.solace.messaging.receiver.MessageReceiver;
import com.solace.messaging.resources.Topic;
import com.solace.messaging.resources.TopicSubscription;

import java.util.Properties;
import java.util.concurrent.CountDownLatch;

public class SolaceConsumer {
    public static void main(String[] args) throws InterruptedException {
        final Properties properties = new Properties();
        CountDownLatch latch = new CountDownLatch(1);
        properties.setProperty(SolaceProperties.TransportLayerProperties.HOST, "xx.xx.xx.xx:55555");          // host:port
        properties.setProperty(SolaceProperties.ServiceProperties.VPN_NAME,  "default");     // message-vpn
        properties.setProperty(SolaceProperties.AuthenticationProperties.SCHEME_BASIC_USER_NAME, "admin");      // client-username
        properties.setProperty(SolaceProperties.AuthenticationProperties.SCHEME_BASIC_PASSWORD, "admin");  // client-password

        properties.setProperty(SolaceProperties.ServiceProperties.RECEIVER_DIRECT_SUBSCRIPTION_REAPPLY, "true");  // subscribe Direct subs after reconnect

        final MessagingService messagingService = MessagingService.builder(ConfigurationProfile.V1)
                .fromProperties(properties).build().connect();  // blocking connect to t



        final DirectMessageReceiver receiver = messagingService.createDirectMessageReceiverBuilder()
                .withSubscriptions(TopicSubscription.of("hello")).build().start();
        final MessageReceiver.MessageHandler messageHandler = (inboundMessage) -> {
            System.out.printf("consumer RECEIVED A MESSAGE %s ",inboundMessage.getPayloadAsString());  //
            System.out.println();
        };
        receiver.receiveAsync(messageHandler);
        latch.await();




    }
}
