springboot-整合rabbitmq

一、maven的依赖

　　

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.7.RELEASE</version>
    </parent>
    <properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
       
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <!-- 添加springboot对amqp的支持 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>
        
      
    </dependencies>

二、yml的配置

　　

spring:            
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: 123456
    virtualHost: /
    publisher-returns: true  
    publisher-confirms: true  
    listener:
      direct:
        prefetch: 100
        concurrency: 200
        max-concurrency: 300
       

三、配置类

　　

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.HeadersExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.amqp.SimpleRabbitListenerContainerFactoryConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


import lombok.extern.slf4j.Slf4j;

@Configuration
@Slf4j
public class RabbitConfig {
    
    
        @Value("${spring.rabbitmq.publisher-confirms}")
        private boolean publisherConfirms = true;

        @Bean(name="secondConnectionFactory")
        public ConnectionFactory secondConnectionFactory(
          @Value("${spring.rabbitmq.host}") String host, 
          @Value("${spring.rabbitmq.port}") String port,
          @Value("${spring.rabbitmq.username}") String username,
          @Value("${spring.rabbitmq.password}") String password ){
             CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
             connectionFactory.setAddresses(host+":"+port);
             connectionFactory.setUsername(username);
             connectionFactory.setPassword(password);
          
            
             connectionFactory.setPublisherConfirms(publisherConfirms);
             return connectionFactory;  
            }
　　　　

            @Bean(name="rabbitTemplate")
            public RabbitTemplate  rabbitTemplate(@Qualifier("secondConnectionFactory") 
                    ConnectionFactory connectionFactory
                    ){
                         RabbitTemplate rabbitTemplate= new RabbitTemplate(connectionFactory);
                         return rabbitTemplate;
                }

                @Bean(name="rabbitFactory")
                public SimpleRabbitListenerContainerFactory rabbitFactory(
                             SimpleRabbitListenerContainerFactoryConfigurer configurer,
                             @Qualifier("secondConnectionFactory") ConnectionFactory connectionFactory   
                             ) {
                 
                    SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
                 
                    configurer.configure(factory, connectionFactory);
                
                    return factory;
                    }  　　
 
                
    }
