SpringBoot整合RocketMQ，三種測試附帶源碼【rocketmq-spring-boot-starter】

我們整合boot項目的時候都是引入 xxx-start 依賴，但是現在大多數的整合RocketMQ都還不是這樣。
我花了一天時間使用rocketmq-spring-boot-starter整合，使得操作起來更加簡單。

1、說明

1-1：rocketmq-spring-boot-starter 提供了一個 rocketMQTemplate 使得發消息更加簡單，它底層也還是基於DefaultMQProducer 但是封裝之後使用更加方便了。

1-2：rocketmq-spring-boot-starter使用監聽器的方式獲取消息更加的簡單

1-3：下面代碼提供三種基礎的消息發送測試【同步、異步、單向】你只需要修改yml文件裏面的RocketMQ地址就好了

1-4：更多內容可以查看官網文檔 https://github.com/apache/rocketmq-spring

2-2：application

server:
  port: 80

rocketmq:
  name-server: xxxxxxx:9876
  producer:
    send-message-timeout: 300000
    group: rocketmq-group

3、測試

3-1：http://localhost/syncNews

3-2：http://localhost/asynNews

3-3：http://localhost/sendOneWay

ps：我們會看到打印的message信息，你可以使用JSON去格式化獲取自己想要的信息。消息有短暫的延遲。
