springboot集成rabbitmq（實戰）
RabbitMQ簡介
RabbitMQ使用Erlang語言開發的開源消息隊列系統，基於AMQP協議來實現（AMQP的主要特徵是面向消息、隊列、路由、可靠性、安全）。支持多種客戶端，如：Python、Ruby、.NET、Java、JMS、C、PHP、ActionScript、XMPP、STOMP等，支持AJAX。用於在分佈式系統中存儲轉發消息，在易用性、擴展性、高可用性等方面表現很出色。html
相關概念java
消息隊列一般有三個概念：發送消息（生產者）、隊列、接收消息（消費者）。RabbitMQ在這個基本概念之上，多作了一層抽象，在發送消息和隊列之間，加入了交換機。這樣發送消息和隊列就沒有直接關係，而是經過交換機來作轉發，交換機會根據分發策略把消息轉給隊列。git
圖一（MQ基本模型）：spring
P爲發送消息（生產者）、Q爲消息隊列、C爲接收消息（消費者）api
圖二（RabbitMQ模型）：緩存
P爲發送消息（生產者）、X爲交換機、Q爲消息隊列、C爲接收消息（消費者）安全
圖一 圖二springboot
RabbitMQ比較重要的幾個概念：多線程
虛擬主機：RabbitMQ支持權限控制，可是最小控制粒度爲虛擬主機。一個虛擬主機能夠包含多個交換機、隊列、綁定。app
交換機：RabbitMQ分發器，根據不一樣的策略將消息分發到相關的隊列。
隊列：緩存消息的容器。
綁定：設置交換機與隊列的關係。
是時候表演真正的技術了
爲了方便演示，咱們分別建立兩個springboot項目：
spring-boot-rabbitmq-producer（生產者）
spring-boot-rabbitmq-consumer（消費者）
注意：實際項目中，一個系統可能即爲生產者、又爲消費者。
1.添加基礎配置
生產者、消費者基礎配置相同。
1.1）集成rabbitmq，添加maven依賴
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies>
1.2）添加rabbitmq服務配置（application.properties）
#rabbitmq相關配置
spring.rabbitmq.host=192.168.15.131
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=123456
2.交換機——DirectExchange
DirectExchange是RabbitMQ的默認交換機，直接使用routingKey匹配隊列。
2.1）添加一個配置類（消費者）
配置一個routingKey爲notify.payment的消息隊列
@Configuration
public class DirectConfig {
@Bean
public Queue paymentNotifyQueue() {
return new Queue("notify.payment");
}
}
2.2）添加一個消息監聽類（消費者）
監聽routingKey爲notify.payment的隊列消息
@Component
@RabbitListener(queues = "notify.payment")
public class PaymentNotifyReceive {
@RabbitHandler
public void receive(String msg) {
LogUtil.info("notify.payment receive message: "+msg);
}
}
2.3）添加一個消息發送類（生產者）
將消息發送至默認的交換機且routingKey爲notify.payment
@Component
public class PaymentNotifySender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void sender(String msg){
LogUtil.info("notify.payment send message: "+msg);
rabbitTemplate.convertAndSend("notify.payment", msg);
}
}
2.4）添加一個測試類（生產者）
@RunWith(SpringRunner.class)
@SpringBootTest
public class PaymentNotifySenderTests {
@Autowired
private PaymentNotifySender sender;
@Test
public void test_sender() {
sender.sender("支付訂單號："+System.currentTimeMillis());
}
}
2.5）執行test_sender()方法
生產者日誌：

分析日誌：
從生產者日誌第7行能夠看出，消息已經成功發送。
從消費者日誌能夠看出，消息已經成功接收。
3.交換機——TopicExchange
TopicExchange是按規則轉發消息，是交換機中最靈活的一個。也是最經常使用的一個。
3.1）添加一個配置類（消費者）
配置一個routingKey爲api.core的消息隊列並綁定在coreExchange交換機上（交換機的匹配規則爲api.core.*）
配置一個routingKey爲api.payment的消息隊列並綁定在paymentExchange交換機上（交換機的匹配規則爲api.payment.#）
@Configuration
public class TopicConfig {
@Bean
public Queue coreQueue() {
return new Queue("api.core");
}
@Bean
public Queue paymentQueue() {
return new Queue("api.payment");
}
@Bean
public TopicExchange coreExchange() {
return new TopicExchange("coreExchange");
}
@Bean
public TopicExchange paymentExchange() {
return new TopicExchange("paymentExchange");
}
@Bean
public Binding bindingCoreExchange(Queue coreQueue, TopicExchange coreExchange) {
return BindingBuilder.bind(coreQueue).to(coreExchange).with("api.core.*");
}
@Bean
public Binding bindingPaymentExchange(Queue paymentQueue, TopicExchange paymentExchange) {
return BindingBuilder.bind(paymentQueue).to(paymentExchange).with("api.payment.#");
}
}
3.2）添加兩個消息監聽類（消費者）
監聽routingKey爲api.core的隊列消息
@Component
public class ApiCoreReceive {
@RabbitHandler
@RabbitListener(queues = "api.core")
public void user(String msg) {
LogUtil.info("api.core receive message: "+msg);
}
}
監聽routingKey爲api.payment的隊列消息
@Component
public class ApiPaymentReceive {
@RabbitHandler
@RabbitListener(queues = "api.payment")
public void order(String msg) {
LogUtil.info("api.payment.order receive message: "+msg);
}
}
3.3）添加兩個消息發送類（生產者）
添加一個user()方法，發送消息至coreExchange交換機且routingKey爲api.core.user
添加一個userQuery()方法，發送消息至coreExchange交換機且routingKey爲api.core.user.query
@Component
public class ApiCoreSender {
@Autowired
private AmqpTemplate rabbitTemplate;

rabbitTemplate.convertAndSend("paymentExchange", "api.payment.order.detail.query", msg);
}
}
3.4）添加兩個測試類（生產者）
測試ApiCoreSender類中的相關方法
@RunWith(SpringRunner.class)
@SpringBootTest
public class ApiCoreSenderTests {
@Autowired

sender.orderDetailQuery("查詢訂單詳情信息！");
}
}
3.5）驗證
3.5.1）執行ApiCoreSenderTests測試類
生產者日誌：
2018-05-14 16:30:05.804 INFO 7340 --- [ main] c.lianjinsoft.sender.ApiCoreSenderTests : Starting ApiCoreSenderTests on LAPTOP-1DF7S904 with PID 7340 (started by lianjinsoft in ... 2018-05-14 16:30:05.805 INFO 7340 --- [ main] c.lianjinsoft.sender.ApiCoreSenderTests : No active profile set, falling back to default profiles: default 2018-05-14 16:30:05.851 INFO 7340 --- [ main] s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@1e800aaa: ... 2018-05-14 16:30:06.553 INFO 7340 --- [ main] trationDelegate$BeanPostProcessorChecker : Bean 'org.springframework.amqp.rabbit.annotation.RabbitBootstrapConfiguration' of type ... 2018-05-14 16:30:07.375 INFO 7340 --- [ main] o.s.c.support.DefaultLifecycleProcessor : Starting beans in phase 2147483647 2018-05-14 16:30:07.385 INFO 7340 --- [ main] c.lianjinsoft.sender.ApiCoreSenderTests : Started ApiCoreSenderTests in 1.922 seconds (JVM running for 2.846) 2018-05-14 16:30:07.431 INFO 7340 --- [ main] com.lianjinsoft.util.LogUtil : api.core.user send message: 用戶管理！ 2018-05-14 16:30:07.463 INFO 7340 --- [ main] o.s.a.r.c.CachingConnectionFactory : Attempting to connect to: [192.168.15.131:5672] 2018-05-14 16:30:07.578 INFO 7340 --- [ main] o.s.a.r.c.CachingConnectionFactory : Created new connection: rabbitConnectionFactory#56ace400:0/SimpleConnection@773cbf4f... 2018-05-14 16:30:07.647 INFO 7340 --- [ main] com.lianjinsoft.util.LogUtil : api.core.user.query send message: 查詢用戶信息！ 2018-05-14 16:30:07.716 INFO 7340 --- [ Thread-2] s.c.a.AnnotationConfigApplicationContext : Closing org.springframework.context.annotation.AnnotationConfigApplicationContext@1e800aaa: ... 2018-05-14 16:30:07.728 INFO 7340 --- [ Thread-2] o.s.c.support.DefaultLifecycleProcessor : Stopping beans in phase 2147483647
消費者日誌：
2018-05-14 16:30:07.609 INFO 14876 --- [cTaskExecutor-1] com.lianjinsoft.util.LogUtil : api.core receive message: 用戶管理！
分析日誌：
從生產者日誌第七、10行能夠看出，api.core.user和api.core.user.query消息均已發送成功。
從消費者日誌能夠看出，只有api.core.user發送的消息被收到了。
問題：
爲何api.core.user.query發送的消息沒有被api.core隊列監聽消費？
答：由於在TopicConfig配置類中，咱們對api.core隊列綁定的交換機規則是api.core.*，而通配符「*」只能向後多匹配一層路徑。
3.5.2）執行ApiPaymentSenderTests測試類

從消費者日誌能夠看出，api.payment.order隊列監聽到了全部消息並均處理成功了。
知識點：
TopicExchange交換機支持使用通配符*、#
*號只能向後多匹配一層路徑。
#號能夠向後匹配多層路徑。
4.交換機——HeadersExchange
HeadersExchange交換機是根據請求消息中設置的header attribute參數類型來匹配的（和routingKey沒有關係）。
4.1）添加一個配置類（消費者）
配置一個routingKey爲credit.bank的消息隊列並綁定在creditBankExchange交換機上
配置一個routingKey爲credit.finance的消息隊列並綁定在creditFinanceExchange交換機上
@Configuration
public class HeadersConfig {

}
@Bean
public Queue creditFinanceQueue() {
return new Queue("credit.finance");
}
@Bean
public HeadersExchange creditBankExchange() {
return new HeadersExchange("creditBankExchange");
}
@Bean
public HeadersExchange creditFinanceExchange() {
return new HeadersExchange("creditFinanceExchange");
}
@Bean
public Binding bindingCreditAExchange(Queue creditBankQueue, HeadersExchange creditBankExchange) {
Map<String,Object> headerValues = new HashMap<>();
headerValues.put("type", "cash");
headerValues.put("aging", "fast");
return BindingBuilder.bind(creditBankQueue).to(creditBankExchange).whereAll(headerValues).match();
}
@Bean
public Binding bindingCreditBExchange(Queue creditFinanceQueue, HeadersExchange creditFinanceExchange) {
Map<String,Object> headerValues = new HashMap<>();
headerValues.put("type", "cash");
headerValues.put("aging", "fast");
return BindingBuilder.bind(creditFinanceQueue).to(creditFinanceExchange).whereAny(headerValues).match();
}
}
4.2）添加一個消息監聽類（消費者）
添加creditBank()方法，監聽routingKey爲credit.bank的隊列消息
添加creditFinance()方法，監聽routingKey爲credit.finance的隊列消息
@Component
public class ApiCreditReceive {
@RabbitHandler
@RabbitListener(queues = "credit.bank")
public void creditBank(String msg) {
LogUtil.info("credit.bank receive message: "+msg);
}
@RabbitHandler
@RabbitListener(queues = "credit.finance")
public void creditFinance(String msg) {
LogUtil.info("credit.finance receive message: "+msg);
}
}
4.3）添加一個消息發送類（生產者）
添加一個creditBank()方法，發送消息至creditBankExchange交換機且routingKey爲credit.bank
添加一個creditFinance()方法，發送消息至creditFinanceExchange交換機且routingKey爲credit.finance
@Component
public class ApiCreditSender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void creditBank(Map<String, Object> head, String msg){
LogUtil.info("credit.bank send message: "+msg);
rabbitTemplate.convertAndSend("creditBankExchange", "credit.bank", getMessage(head, msg));
}
public void creditFinance(Map<String, Object> head, String msg){
LogUtil.info("credit.finance send message: "+msg);
rabbitTemplate.convertAndSend("creditFinanceExchange", "credit.finance", getMessage(head, msg));
}
}
4.4）添加一個測試類（生產者）
@RunWith(SpringRunner.class)
@SpringBootTest
public class ApiCreditSenderTests {
@Autowired
private ApiCreditSender sender;
@Test
public void test_creditBank_type() {
Map<String,Object> head = new HashMap<>();
head.put("type", "cash");
sender.creditBank(head, "銀行授信(部分匹配)");
}
@Test
public void test_creditBank_all() {
Map<String,Object> head = new HashMap<>();
head.put("type", "cash");
head.put("aging", "fast");
sender.creditBank(head, "銀行授信(所有匹配)");
}
@Test
public void test_creditFinance_type() {
Map<String,Object> head = new HashMap<>();
head.put("type", "cash");
sender.creditFinance(head, "金融公司授信(部分匹配)");
}
@Test
public void test_creditFinance_all() {
Map<String,Object> head = new HashMap<>();
head.put("type", "cash");
head.put("aging", "fast");
sender.creditFinance(head, "金融公司授信(所有匹配)");
}
}
4.5）執行ApiCreditSenderTests測試類

分析日誌：
經過生產者日誌第七、十、十一、12能夠看出，測試的4個方法均已成功發送消息。
經過消費者日誌能夠看出，credit.bank監聽的隊列有一條消息沒有接收到。
問題：
爲何ApiCreditSenderTests.test_creditBank_type()發送的消息，沒有被處理？
答：由於在HeadersConfig配置類中，creditBankExchange交換機的匹配規則是徹底匹配，即header attribute參數必須完成一致。
5.交換機——FanoutExchange
FanoutExchange交換機是轉發消息到全部綁定隊列（廣播模式，和routingKey沒有關係）。
5.1）添加一個配置類（消費者）
配置一個routingKey爲api.report.payment的消息隊列並綁定在reportExchange交換機上
配置一個routingKey爲api.report.refund的消息隊列並綁定在reportExchange交換機上
@Configuration
public class FanoutConfig {
@Bean
public Queue reportPaymentQueue() {
return new Queue("api.report.payment");
}
@Bean
public Queue reportRefundQueue() {
return new Queue("api.report.refund");
}
@Bean
public FanoutExchange reportExchange() {
return new FanoutExchange("reportExchange");
}
@Bean
public Binding bindingReportPaymentExchange(Queue reportPaymentQueue, FanoutExchange reportExchange) {
return BindingBuilder.bind(reportPaymentQueue).to(reportExchange);
}
@Bean
public Binding bindingReportRefundExchange(Queue reportRefundQueue, FanoutExchange reportExchange) {
return BindingBuilder.bind(reportRefundQueue).to(reportExchange);
}
}
5.2）添加一個消息監聽類（消費者）
添加payment()方法，監聽routingKey爲api.report.payment的隊列消息
添加refund()方法，監聽routingKey爲api.report.refund的隊列消息
@Component
public class ApiReportReceive {
@RabbitHandler
@RabbitListener(queues = "api.report.payment")
public void payment(String msg) {
LogUtil.info("api.report.payment receive message: "+msg);
}
@RabbitHandler
@RabbitListener(queues = "api.report.refund")
public void refund(String msg) {
LogUtil.info("api.report.refund receive message: "+msg);
}
}
5.3）添加一個消息發送類（生產者）
添加一個generateReports()方法，發送消息至reportExchange交換機
@Component
public class ApiReportSender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void generateReports(String msg){
LogUtil.info("api.generate.reports send message: "+msg);
rabbitTemplate.convertAndSend("reportExchange", "api.generate.reports", msg);
}
}
5.4）添加一個測試類（生產者）
@RunWith(SpringRunner.class)
@SpringBootTest
public class ApiReportSenderTests {
@Autowired
private ApiReportSender sender;
@Test
public void test_generateReports() {
sender.generateReports("開始生成報表！");
}
}
5.5）執行ApiReportSenderTests測試類

6.多對一
在實際項目中，咱們的系統一般會作集羣、分佈式或災備部署。那麼就會出現一對多、多對一或多對多的場景。
那麼我們本地如何模擬多對一呢？
6.1）爲了測試方便，咱們複用PaymentNotifyReceive案例，在PaymentNotifySenderTests測試類中，增長測試方法
test_sender_many2one_1：請求參數爲偶數
test_sender_many2one_2：請求參數爲奇數
@Test
public void test_sender_many2one_1() throws Exception {
for (int i = 0; i < 20; i+=2) {
sender.sender("支付訂單號："+i);
Thread.sleep(1000);
}
}
@Test
public void test_sender_many2one_2() throws Exception {
for (int i = 1; i < 20; i+=2) {
sender.sender("支付訂單號："+i);
Thread.sleep(1000);
}
}
6.2）執行test_sender_many2one_1()、test_sender_many2one_2()方法

7.一對多
如何模擬一對多？
7.1）爲了測試方便，咱們繼續複用PaymentNotifyReceive案例，在PaymentNotifySenderTests測試類中，增長測試方法
test_sender_one2many：循環調用20次。
@Test
public void test_sender_one2many() {
for (int i = 0; i < 20; i++) {
sender.sender("支付訂單號："+i);
}
}
7.2）測試
爲了達到一對多的效果，咱們須要多啓動一個（或多個）消費者。而後執行test_sender_one2many()測試方法。

分析日誌：
從生產者日誌能夠看出，全部的消息均已經發送成功。
從消費者一、消費者2日誌能夠看出，消息被兩個消費者均衡消費了。
8.發送對象
實際項目中，請求信息可能包含多個字段。爲了保證生產者與消費者兩端的字段一致性，一般會傳遞一個對象。
8.1）爲了測試方便，咱們在DirectConfig中增長一個消息隊列
@Bean
public Queue refundNotifyQueue() {
return new Queue("notify.refund");
}
8.2）添加一個消息監聽類（消費者）
監聽routingKey爲notify.refund的隊列消息
@Component
@RabbitListener(queues = "notify.refund")
public class RefundNotifyReceive {
@RabbitHandler
public void receive(Order order) {
LogUtil.info("notify.refund receive message: "+order);
}
}
8.3）添加一個消息發送類（生產者）
@Component
public class RefundNotifySender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void sender(Order order){
LogUtil.info("notify.refund send message: "+order);
rabbitTemplate.convertAndSend("notify.refund", order);
}
}
8.4）添加一個測試類
@RunWith(SpringRunner.class)
@SpringBootTest
public class RefundNotifySenderTests {
@Autowired
private RefundNotifySender sender;
@Test
public void test_sender() {
Order order = new Order();
order.setId(100001);
order.setOrderId(String.valueOf(System.currentTimeMillis()));
order.setAmount(new BigDecimal("1999.99"));
order.setCreateTime(new Date());
sender.sender(order);
}
}
8.5）執行RefundNotifySenderTests測試類

消費者日誌：
2018-05-14 16:37:49.242 INFO 14876 --- [cTaskExecutor-1] com.lianjinsoft.util.LogUtil : notify.refund receive message: Order [id=100001, orderId=1526287069081, amount=1999.99, createTime=...
分析日誌：
從生產者日誌能夠看出，order對象已經發送成功。
從消費者日誌能夠看出，order對象已經接受成功並能夠直接使用。
注意：
傳遞的對象必須支持序列化（實現了Serializable接口）
9.RPC
RabbitMQ支持RPC遠程調用，同步返回結果。
9.1）爲了測試方便，咱們在DirectConfig中增長一個消息隊列
@Bean
public Queue queryOrderQueue() {
return new Queue("query.order");
}
9.2）添加一個消息監聽類（消費者）
監聽routingKey爲query.order的隊列消息
@Component
@RabbitListener(queues = "query.order")
public class QueryOrderReceive {
@RabbitHandler
public Order receive(String orderId) {
LogUtil.info("notify.refund receive message: "+orderId);
Order order = new Order();
order.setId(100001);
order.setOrderId(orderId);
order.setAmount(new BigDecimal("2999.99"));
order.setCreateTime(new Date());
return order;
}
}
9.3）添加一個消息發送類（生產者）
@Component
public class QueryOrderSender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void sender(String orderId){
LogUtil.info("query.order send message: "+orderId);
Order order = (Order) rabbitTemplate.convertSendAndReceive("query.order", orderId);
LogUtil.info("query.order return message: "+order);
}
}
9.4）添加一個測試類
@RunWith(SpringRunner.class)
@SpringBootTest
public class QueryOrderSenderTests {
@Autowired
private QueryOrderSender sender;
@Test
public void test_sender() {
sender.sender("900000001");
}
}
9.5）執行QueryOrderSenderTests測試類
生產者日誌：
2018-05-14 16:38:14.163 INFO 2024 --- [ main] c.l.sender.QueryOrderSenderTests : Starting QueryOrderSenderTests on LAPTOP-1DF7S904 with PID 2024 (started by lianjinsoft in... 2018-05-14 16:38:14.164 INFO 2024 --- [ main] c.l.sender.QueryOrderSenderTests : No active profile set, falling back to default profiles: default 2018-05-14 16:38:14.197 INFO 2024 --- [ main] s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@7eac9008: ... 2018-05-14 16:38:14.848 INFO 2024 --- [ main] trationDelegate$BeanPostProcessorChecker : Bean 'org.springframework.amqp.rabbit.annotation.RabbitBootstrapConfiguration' of type ... 2018-05-14 16:38:15.705 INFO 2024 --- [ main] o.s.c.support.DefaultLifecycleProcessor : Starting beans in phase 2147483647 2018-05-14 16:38:15.715 INFO 2024 --- [ main] c.l.sender.QueryOrderSenderTests : Started QueryOrderSenderTests in 1.927 seconds (JVM running for 3.079) 2018-05-14 16:38:15.793 INFO 2024 --- [ main] com.lianjinsoft.util.LogUtil : query.order send message: 900000001 2018-05-14 16:38:15.812 INFO 2024 --- [ main] o.s.a.r.c.CachingConnectionFactory : Attempting to connect to: [192.168.15.131:5672] 2018-05-14 16:38:15.988 INFO 2024 --- [ main] o.s.a.r.c.CachingConnectionFactory : Created new connection: rabbitConnectionFactory#38be305c:0/SimpleConnection@71984c3 ... 2018-05-14 16:38:16.057 INFO 2024 --- [ main] com.lianjinsoft.util.LogUtil : query.order return message: Order [id=100001, orderId=900000001, amount=2999.99, createTime=... 2018-05-14 16:38:16.079 INFO 2024 --- [ Thread-2] s.c.a.AnnotationConfigApplicationContext : Closing org.springframework.context.annotation.AnnotationConfigApplicationContext@7eac9008: ... 2018-05-14 16:38:16.097 INFO 2024 --- [ Thread-2] o.s.c.support.DefaultLifecycleProcessor : Stopping beans in phase 2147483647
消費者日誌：
2018-05-14 16:38:16.028 INFO 14876 --- [cTaskExecutor-1] com.lianjinsoft.util.LogUtil : notify.refund receive message: 900000001
分析日誌：
從生產者日誌第7行能夠看出，消息已經發送成功。從第10行日誌能夠看出，已經收取到返回的消息，併成功轉化爲Order對象。
從消費者日誌能夠看出，已經成功接收到消息並處理完成。
雖然RabbitMQ支持RPC接口調用，但不推薦使用。
緣由：
1）RPC默認爲單線程阻塞模型，效率極低。
2）須要手動實現多線程消費。
安裝RabbitMQ請參考：CentOS在線安裝RabbitMQ3.7
