RabbitMQ是一个由Erlang语言编写的消息中间件它遵循AMQP协议提供了稳定可靠的消息传输服务。RabbitMQ通过其独特的架构和丰富的功能帮助开发者解决分布式系统中的消息传递问题提高系统的可扩展性、可靠性和响应速度。
2.添加依赖
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-amqp/artifactId/dependency3.配置RabbitMQ连接
在application.properties或application.yml中配置RabbitMQ服务器的连接参数
# 定义RabbitMQ的主机地址这里使用的是局域网内的一个IP地址
spring.rabbitmq.host192.168.131.130# 指定RabbitMQ的端口号默认情况下RabbitMQ使用5672端口
spring.rabbitmq.port5672# 设置RabbitMQ的用户名这里使用的是默认的用户名guest
spring.rabbitmq.usernameguest# 设置RabbitMQ的密码这里使用的是默认的密码guest
spring.rabbitmq.passwordguest# 配置RabbitMQ的虚拟主机这里使用的是默认的虚拟主机/
spring.rabbitmq.virtual-host/4.DirectExchange
4.1 消费者
Configuration

//放入Ioc容器

Service
public class FanoutProvider {Resourceprivate RabbitTemplate rabbitTemplate;public void send(JSONObject message) {rabbitTemplate.convertAndSend(Fanout_E01,,message.get(msg));}

发送请求进行测试

RequestMapping(/fanout)
public class FanoutController {Resourceprivate FanoutProvider fanoutProvider;PostMapping(/send)public void send(RequestBody JSONObject message) {fanoutProvider.send(message);}
