SpringBoot 消息队列RabbitMQ 消息转换器 改变消息的发送格式 节省内存

生产者

private  final RabbitTemplate rabbitTemplate;
@GetMapping("/putRecord") //插入记录
public Result userMessage(){
    Map<String ,String> map =new HashMap<>();
    map.put("name","生产队的驴");
    map.put("qq","147258");
    rabbitTemplate.convertAndSend("csdn.fanout","a",map);
    return  Result.success("操作成功",null);
}

生产者正常发送消息，而到了队列就变成了这样，自动转换成字节导致体积变大。

消息转换器

导入JSON依赖进行序列化

     <dependency>
            <groupId>com.fasterxml.jackson.dataformat</groupId>
            <artifactId>jackson-dataformat-xml</artifactId>
        </dependency>

声明依赖

在springboot的启动类上声明

@SpringBootApplication
public class Demo1Application {

    public static void main(String[] args) {
        SpringApplication.run(Demo1Application.class, args);
    }

    @Bean
    public MessageConverter jackonMessageConverter(){
        return  new Jackson2JsonMessageConverter();
    }
}
