今天就跟大家聊聊有关怎么进行spring boot rabbitMQ RPC实现，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

环境配置

package com.example.demo;import org.springframework.amqp.core.Binding;import org.springframework.amqp.core.BindingBuilder;import org.springframework.amqp.core.DirectExchange;import org.springframework.amqp.core.Queue;import org.springframework.amqp.rabbit.annotation.EnableRabbit;import org.springframework.amqp.rabbit.connection.ConnectionFactory;import org.springframework.amqp.rabbit.core.RabbitTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.beans.factory.config.ConfigurableBeanFactory;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.Scope;@Configuration@EnableRabbitpublic class RabbitMQConfigurer { @Autowired private ConnectionFactory connectionFactory; @Bean @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE) public RabbitTemplate rabbitTemplate() { //必须是prototype类型 //Reply received after timeout RabbitTemplate rabbitTemplate = new RabbitTemplate(this.connectionFactory); rabbitTemplate.setReceiveTimeout(9000); return rabbitTemplate; } @Bean @Qualifier("rpcTestExchange") public DirectExchange rpcTestExchange() { return new DirectExchange("rpcTest"); } @Bean public Queue rpcTestQueue() { return new Queue("rpcTestQueue"); } @Bean public Binding rpcTestBind() { return BindingBuilder.bind(rpcTestQueue()).to(rpcTestExchange()).with("addUser"); }}

server 端

package com.example.demo;import com.rabbitmq.client.Channel;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.amqp.rabbit.annotation.RabbitHandler;import org.springframework.amqp.rabbit.annotation.RabbitListener;import org.springframework.amqp.rabbit.core.RabbitTemplate;import org.springframework.amqp.support.AmqpHeaders;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.messaging.handler.annotation.Header;import org.springframework.messaging.handler.annotation.Payload;import org.springframework.stereotype.Component;@Component@RabbitListener(queues = "rpcTestQueue")public class UserServer { private static final Logger LOGGER = LoggerFactory.getLogger(UserServer.class); private final RabbitTemplate rabbitTemplate; @Autowired public UserServer(RabbitTemplate rabbitTemplate) { this.rabbitTemplate = rabbitTemplate; } @RabbitHandler public void process(@Payload String payload, Channel channel, @Header(AmqpHeaders.REPLY_TO) String replyTo, @Header(AmqpHeaders.CORRELATION_ID) String correlationId) throws Exception { LOGGER.info("====== server receive data 【{}】 ====== ", payload); this.rabbitTemplate.convertAndSend(replyTo, "then " + payload + " is create", message -> { message.getMessageProperties().setCorrelationId(correlationId); return message; }); LOGGER.info("====== server response queue 【{}】 ======", replyTo); }}

client 端

package com.example.demo;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.amqp.rabbit.core.RabbitTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import java.util.Arrays;@Componentpublic class Client { private static final Logger LOGGER = LoggerFactory.getLogger(Client.class); private final RabbitTemplate rabbitTemplate; @Autowired public Client(RabbitTemplate rabbitTemplate) { this.rabbitTemplate = rabbitTemplate; } public void doRequest() { for (String name : Arrays.asList("张三", "李四", "王五")) { LOGGER.info("---- client send user name is 【{}】", name); Object response = this.rabbitTemplate.convertSendAndReceive("rpcTest", "addUser", name); LOGGER.info("---- and response is : {} -------", response); } }}

客户端：

在请求发送消息之前，创建一个【匿名队列】绑定至默认的交换机（即 /）。将队【匿名队列】名称放在 reply_to 中与消息一起发送。

服务端：

处理理消息后，将应答消息发送至默认交换机即(/)。
