轉換流,,,,, 緩衝流,,,,,Properties類,,,,,序列化流與反序列化流

1.匯入相應依賴

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2.在測試類裡進行測試

package com.ws;

import org.junit.jupiter.api.Test;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import
org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import java.util.Arrays; import java.util.HashMap; import java.util.Map; @SpringBootTest class Springboot02AmqpApplicationTests { @Autowired RabbitTemplate rabbitTemplate; @Test
void contextLoads() { /*message需要自己構造一個;定義訊息體內容和訊息頭 *rabbitTemplate.send(exchange,routeKey,message) * * object預設當成訊息體,只需要傳入傳送的物件,自動序列化發給rabbitmq * rabbitTemplate.convertAnd Send(exchange,routeKey,object) * */ Map<String, Object> map = new HashMap<>(); map.put(
"msg","one"); map.put("data", Arrays.asList("HelloWorld",111)); rabbitTemplate.convertAndSend("exchange.direct","ws.news",map); } @Test void test2(){ Object o = rabbitTemplate.receiveAndConvert("ws.news"); System.out.println(o.getClass()); System.out.println(o); } }

3.編寫自己的序列化Bean

import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.amqp.support.converter.MessageConverter;

@Configuration
public class MyAMQPConfig {
    @Bean
    public MessageConverter messageConverter(){
      return new Jackson2JsonMessageConverter();
    }
}
