SpringBoot应用程序发布并读取ActiveMQ主题

我有两个应该从一个主题中读取的接收器。但只有一个随机接收者收到消息，就像它实际上是从队列而不是主题中读取的一样。我读了this https://stackoverflow.com/questions/40144561/how-to-listen-to-topic-using-spring-boot-jms答案，但似乎不起作用。这是我的代码。

应用程序.java：

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.support.converter.MappingJackson2MessageConverter;
import org.springframework.jms.support.converter.MessageConverter;
import org.springframework.jms.support.converter.MessageType;

import javax.jms.ConnectionFactory;

@SpringBootApplication
@EnableJms
public class Application {
    public static final String MAILBOX_TOPIC = "inbox.topic";

    public static void main(String[] args) {
        // Launch the application
        ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);

        JmsTemplate jmsTemplate = context.getBean(JmsTemplate.class);

        // Send a message with a POJO - the template reuse the message converter
        System.out.println("Sending an email message.");
        jmsTemplate.convertAndSend(MAILBOX_TOPIC, new Email("[email protected] /cdn-cgi/l/email-protection", "Hello"));
    }

    @Bean
    public JmsListenerContainerFactory<?> topicListenerFactory(ConnectionFactory connectionFactory,
                                                               DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setPubSubDomain(true);
        configurer.configure(factory, connectionFactory);
        return factory;
    }

    @Bean // Serialize message content to json using TextMessage
    public MessageConverter jacksonJmsMessageConverter() {
        MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
        converter.setTargetType(MessageType.TEXT);
        converter.setTypeIdPropertyName("_type");
        return converter;
    }
}

FirstReceiver.java：

package hello;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;
import static hello.Application.MAILBOX_TOPIC;

@Component
public class FirstReceiver {

    @JmsListener(destination = MAILBOX_TOPIC, containerFactory = "topicListenerFactory")
    public void receiveMessage(Email email) {
        System.out.println("FirstReceiver <" + email + ">");
    }

}

SecondReceiver.java：

package hello;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

import static hello.Application.MAILBOX_TOPIC;

@Component
public class SecondReceiver {
    @JmsListener(destination = MAILBOX_TOPIC, containerFactory = "topicListenerFactory")
    public void receiveMessage(Email email) {
        System.out.println("SecondReceiver <" + email + ">");
    }

}

电子邮件.java：

package hello;

public class Email {

    private String to;
    private String body;

    public Email() {
    }

    public Email(String to, String body) {
        this.to = to;
        this.body = body;
    }

    public String getTo() {
        return to;
    }

    public void setTo(String to) {
        this.to = to;
    }

    public String getBody() {
        return body;
    }

    public void setBody(String body) {
        this.body = body;
    }

    @Override
    public String toString() {
        return String.format("Email{to=%s, body=%s}", getTo(), getBody());
    }

}

请帮助我。

add spring.jms.pub-sub-domain=true to application.properties

UPDATE:

你需要改变两件事：

1.

@Bean
public JmsListenerContainerFactory<?> topicListenerFactory(ConnectionFactory connectionFactory,
                                                           DefaultJmsListenerContainerFactoryConfigurer configurer) {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    // the configurer will use PubSubDomain from application.properties if defined or false if not
    //so setting it on the factory level need to be set after this
    configurer.configure(factory, connectionFactory);
    factory.setPubSubDomain(true);
    return factory;
}

2.

    jmsTemplate.convertAndSend( new ActiveMQTopic(MAILBOX_TOPIC), new Email("[email protected] /cdn-cgi/l/email-protection", "Hello"));

或者注入这个bean
