spring 接入rabbitMq
springMvc-spring-cloud-Stream通過rabbitMq交互
這裏就不贅述了，網上一搜一大把
rabbitMq安裝
首先需要裝rabbitmq，這裏請參考官網資料。這裏只給出Windows和linux 的rpm方式的安裝鏈接。 Windows鏈接；linuxRPM鏈接。
生產者（springMVC）項目接入rabbitmq
- 新建xml配置
文件命名spring-rabbitmq.xml，配置如下：

connectionFactory 連接工廠
- web.xml配置；
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring-rabbitmq.xml
</param-value>
</context-param>
- 生產者代碼
@Autowired
private AmqpTemplate amqpTemplate;
@Override
public void produce(final Order order) {
logger.info("回調隊列destination: queue.queue1.queue1Consumers");
logger.info("order: " + order);
String json = JSON.toJSONString(order);
amqpTemplate.convertAndSend("queue.queue1.queue1Consumers",order);
}
消費者（spring-cloud-stream）項目接入rabbitmq
- 配置文件 application.yml
spring:
cloud:
stream:
bindings:
queue1: # 這個名字是一個通道的名稱
destination: queue.queue1 # 目的，對應 MQ 是 exchange， 生成臨時隊列
content-type: text/plain
binder: local_rabbit # 綁定器名稱
group: queue1Consumers # 進行操作的分組，實際上就表示持久化--消費端配置
queue2: # 這個名字是一個通道的名稱
destination: queue.queue2 # 目的，對應 MQ 是 exchange， 生成臨時隊列
binder: local_rabbit # 綁定器名稱
group: queue2Consumers # 進行操作的分組，實際上就表示持久化--消費端配置
queue3: # 這個名字是一個通道的名稱
destination: queue.queue3 # 目的，對應 MQ 是 exchange， 生成臨時隊列
content-type: application/json # 設置消息類型，本次爲對象json，如果是文本則設置“text/plain”
binder: local_rabbit # 綁定器名稱
group: queue3Consumers # 進行操作的分組，實際上就表示持久化--消費端配置
--消費端配置
binders: # 在此處配置要綁定的rabbitmq的服務信息；
local_rabbit: # rabbitmq的服務名稱
type: rabbit
environment:
spring:
rabbitmq:
host: 127.0.0.1
port: 5672
username: guest
password: guest
virtual-host: /
- 自定義通道
public interface ReceviceQueueProcess {
public static final String queue1= "queue1"; // 輸入通道名稱
public static final String queue2= "queue2"; // 輸入通道名稱
public static final String queue3= "queue3"; // 輸入通道名稱
@Input(ReceviceQueueProcess.queue1)
public SubscribableChannel queue1();
@Input(ReceviceQueueProcess.queue2)
public SubscribableChannel queue2();
@Input(ReceviceQueueProcess.queue3)
public SubscribableChannel queue3();
}
- ribbitmq監聽綁定器
@EnableBinding(ReceviceQueueProcess.class)
public class ReceiveMsgHandler {
private Logger logger = Logger.getLogger(getClass())；
@StreamListener(ReceviceQueueProcess.queue1)
public void queue1(Message message) {
logger.info("發送知監聽queue1");
try {
Object body = message.getPayload();
String json = body.toString();
logger.info("消息推送 body:" +json);
logger.info("get message from queue1: " + json);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@StreamListener(ReceviceQueueProcess.queue2)
public void queue2(Message message) {
logger.info("發送通知監聽queue2");
try {
logger.info("發送通知監聽queue2");
Object body = message.getPayload();
String json = body.toString();;
logger.info("推送 json:" + json);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@StreamListener(ReceviceQueueProcess.queue3)
public void queue3(Message message) {
logger.info("發送通知監聽queue3");
try {

Object body = message.getPayload();
String json = body.toString();;
logger.info("推送json:" + json);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();

}
}
