springboot整合activeMq
ActiveMq是Apache提供的开源音讯零碎采纳java实现,
很好地反对JMS(Java Message Service,即Java音讯服务) 标准
ActiveMq装置:http://activemq.apache.org/co… 在官网下载安装对应的版本
下载实现后解压就能够应用
ActiveMq默认的端口号是8161,用户名和明码都是admin 在本机能够应用http://localhost:8161 去拜访
springboot整合ActiveMq
1、导入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
2、在properties文件中配置activeMq
spring.activemq.broker-url=tcp://localhost:61616
#如果是点对点(queue),那么此处默认应该是false,如果公布订阅,那么肯定设置为true
spring.activemq.packages.trust-all=true
spring.activemq.user=admin
spring.activemq.password=admin
3、编写queue(队列)
@Component
public class QueueBean{
//创立一个队列实例
@Bean
Queue queue(){
//这里设置的音讯是队列的名称
return new ActiveMQQueue("hello.javaboy");
}
}
4、创立音讯的发送者以及消费者
@Component
public class JmsComponent{
//springboot提供的音讯模板
@Autowired
JmsMessagingTemplate jmsMessagingTemplate;
//本人创立的队列实例
@Autowired
Queue queue;
/**
* 发送音讯
* @param message
*/
public void send(Message message){
jmsMessagingTemplate.convertAndSend(this.queue,message);
}
/**
* 接管音讯
* @param message
*/
//示意监听该队列名称发来的音讯
@JmsListener(destination = "hello.javaboy")
public void readMessage(Message message){
System.out.println(message);
}
}
5、上述Message实体类
public class Message implements Serializable {
private String content;//音讯主体
private Date sendDate;//音讯发送的工夫
//省略get、set、tostring办法
}
6、进行音讯的发送以及生产
在测试类中注入JmsComponent 调用send()办法进行音讯的转发
@SpringBootTest
class ActivemqApplicationTests {
@Autowired
JmsComponent jmsComponent;
@Test
void contextLoads() {
Message message = new Message();
message.setContent("hello activeMq");
message.setSendDate(new Date());
jmsComponent.send(message);
}
}
首先启动我的项目,在运行测试类进行音讯发送:
控制台会打印消息内容:
springboot整合RabbitMQ
rabbitmq装置比拟繁琐,这里应用docker容器进行装置,docker装置十分不便,一条命令全副搞定
通过docker装置rabbitmq
-P(大p)示意主动映射到主机端口
docker run -d --hostname my-rabbitmq --name some-rabbitmq -P rabbitmq:3-management
首先导入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
编写配置文件:
#配置rabbitMQ
spring.rabbitmq.host=localhost
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.port=32771
RabbitMQ 四种替换模式:
直连交换机:Direct exchange
扇形交换机:Fanout exchange
主体交换机:Topic exchange
首部交换机:Headers exchange
上面别离介绍4中替换模式:
1、Direct exchange
//Direct策略(只转发给routingKey相匹配的用户)
@Configuration
public class RabbitDirectConfig {
public final static String DIRECTNAME = "javaboy-direct";
//音讯队列
@Bean
Queue queue(){
//name值为队列名称,routingKey会与他进行匹配
return new Queue("hello.RabbitMQ");
}
@Bean
Queue queue1(){
return new Queue("hello.RabbitMQ1");
}
@Bean
DirectExchange directExchange(){
//第一个参数为DIRECTNAME、第二个参数示意重启后是否无效,第三参数示意长时间未应用是否删除
return new DirectExchange(DIRECTNAME,true,false);
}
@Bean
Binding binding(){
//将队列queue和DirectExchange绑定在一起
return BindingBuilder.bind(queue()).to(directExchange()).with("direct");
}
@Bean
Binding binding1(){
//将队列queue和DirectExchange绑定在一起
return BindingBuilder.bind(queue1()).to(directExchange()).with("direct");
}
}
2、配置消费者DirectReceiver:
//配置消费者
@Component
public class DirectReceiver {
//只监听queue()队列的音讯
@RabbitListener(queues = "hello.RabbitMQ")
public void hanlder(String msg){
System.out.println("hanlder>>>"+msg);
}
//只监听queue1()队列的音讯
@RabbitListener(queues = "hello.RabbitMQ1")
public void hanlder1(String msg){
System.out.println("hanlder1>>>"+msg);
}
}
测试代码:
在springboot的测试类中注入RabbitTemplate(springboot提供的RabbitMQ模板)
@Autowired
RabbitTemplate rabbitTemplate;
@Test
void contextLoads() {
//两个参数第一个是routingKey、第二个为音讯内容
rabbitTemplate.convertAndSend("hello.RabbitMQ","hello RabbitMQ test");
rabbitTemplate.convertAndSend("hello.RabbitMQ1","hello RabbitMQ test222");
}
启动我的项目后,运行测试类能够看到只有与routingkey相匹配的消费者受到了对应的音讯:
2、Fanout exchange
Fanout策略(只有是与他绑定的队列,都会收到音讯与routingKey无关)
1、配置RabbitFanoutConfig:
//Fanout策略(只有是与他绑定的队列,都会收到音讯与routingKey无关)
@Configuration
public class RabbitFanoutConfig {
public final static String FANOUTNAME = "javaboy-fanout";
//配置了两个音讯队列queueOne和queueTwo
@Bean
Queue queueOne(){
return new Queue("queue-one");
}
@Bean
Queue queueTwo(){
return new Queue("queue-two");
}
@Bean
FanoutExchange fanoutExchange(){
return new FanoutExchange(FANOUTNAME,true,false);
}
//将两个队列与FanoutExchange绑定
@Bean
Binding bindingOne(){
return BindingBuilder.bind(queueOne()).to(fanoutExchange());
}
@Bean
Binding bindingTwo(){
return BindingBuilder.bind(queueTwo()).to(fanoutExchange());
}
}
2、配置消费者FanoutReceiver:
//配置消费者
@Component
public class FanoutReceiver {
//两个消费者别离监听两个不同的队列
@RabbitListener(queues = "queue-one")
public void hanlder1(String msg){
System.out.println("FanoutReceiver:hanlder1>>>"+msg);
}
@RabbitListener(queues = "queue-two")
public void hanlder2(String msg){
System.out.println("FanoutReceiver:hanlder2>>>"+msg);
}
}
3、测试类:
@Test
void rabbitFanout(){
//三个参数示意RabbitFanoutConfig的名称、routingkey、音讯内容
rabbitTemplate.convertAndSend(RabbitFanoutConfig.FANOUTNAME,null,"hello fanout test");
}
该形式与routingkey无关所有写null即可
查看输入:能够看到两个消费者都收到了音讯
3、Topic exchange
topic策略能够依据routingKey的规定(通配符形式)进行去匹配队列进行转发规定为.#. *为单词,#示意含糊匹配
例如routingkey为:xiaomi.# 那么带有xiaomi.结尾的队列都会收到该音讯
routingkey为:#.phone.# 示意音讯的routingKey中带有phone时 就会去匹配带有phone的队列
1、配置RabbitTopicConfig:
/topic策略能够依据routingKey的规定(通配符形式)进行去匹配队列进行转发规定为*.#.*
//*为单词,#示意含糊匹配
@Configuration
public class RabbitTopicConfig {
public final static String TOPICNAME = "javaboy-topic";
@Bean
TopicExchange topicExchange(){
return new TopicExchange(TOPICNAME,true,false);
}
@Bean
Queue xiaomi(){
return new Queue("xiaomi");
}
@Bean
Queue huawei(){
return new Queue("huawei");
}
@Bean
Queue phone(){
return new Queue("phone");
}
@Bean
Binding xiaomiBinding(){
//xiaomi.#:示意音讯的routingKey是以xiaomi结尾的就会路由到xiaomi的队列
return BindingBuilder.bind(xiaomi()).to(topicExchange()).with("xiaomi.#");
}
@Bean
Binding huaweiBinding(){
return BindingBuilder.bind(huawei()).to(topicExchange()).with("huawei.#");
}
@Bean
Binding phoneBinding(){
//#.phone.#:示意音讯的routingKey中带phone的都会路由到phone的队列
return BindingBuilder.bind(phone()).to(topicExchange()).with("#.phone.#");
}
}
2、配置消费者TopicReceiver:
@Component
public class TopicReceiver {
//别离监听名称为xiaomi、huawei、phone的队列
@RabbitListener(queues = "xiaomi")
public void handlerXM(String msg){
System.out.println("TopicReceiver:handlerXM>>>"+msg);
}
@RabbitListener(queues = "huawei")
public void handlerHW(String msg){
System.out.println("TopicReceiver:handlerHW>>>"+msg);
}
@RabbitListener(queues = "phone")
public void handlerPHONE(String msg){
System.out.println("TopicReceiver:handlerPHONE>>>"+msg);
}
}
3、测试类:
@Test
void rabbitTopic(){
//依据匹配规定该音讯只能被xiaomi的队列收到
rabbitTemplate.convertAndSend(RabbitTopicConfig.TOPICNAME,"xiaomi.news","小米新闻");
//依据匹配规定该音讯只能被phone的队列收到
rabbitTemplate.convertAndSend(RabbitTopicConfig.TOPICNAME,"vivo.phone","vivo手机");
//依据匹配规定该音讯能够别huawei和phone两个队列收到
rabbitTemplate.convertAndSend(RabbitTopicConfig.TOPICNAME,"huawei.phone","华为手机");
}
查看输入:
能够看到routingkey为huawei.phone的音讯匹配了两个队列,其余两个都只匹配了一个队列
4、Headers exchange
该模式是依据路由规定的header进行匹配的,在进行匹配的时候须要传入一个map汇合,routingkey去匹配map即可中的key value,匹配规定能够使any或者all,any示意只有蕴含任意信息就能够,all示意所有信息都必须匹配
1、配置RabbitHeaderConfig:
@Configuration
public class RabbitHeaderConfig {
public final static String HEADERNAME = "javaboy-header";
@Bean
HeadersExchange headersExchange(){
return new HeadersExchange(HEADERNAME,true,false);
}
//别离创立两个不同header的队列
@Bean
Queue queueName(){
return new Queue("name-queue");
}
@Bean
Queue queueAge(){
return new Queue("age-queue");
}
@Bean
Binding bindingName(){
Map<String,Object> map = new HashMap<>();
map.put("name","hello");
//示意如果routingKey匹配的map汇合中的key value 就会将音讯转发到对应的路由上
return BindingBuilder.bind(queueName()).to(headersExchange()).whereAny(map).match();
}
@Bean
Binding bindingAge(){
return BindingBuilder.bind(queueAge()).to(headersExchange()).where("age").exists();
}
}
2、创立消费者HeaderReceiver:
@Component
public class HeaderReceiver {
@RabbitListener(queues = "name-queue")
public void handlerName(byte[] msg){
System.out.println("HeaderReceiver:handlerName>>>>"+new String(msg,0,msg.length));
}
@RabbitListener(queues = "age-queue")
public void handlerAge(byte[] msg){
System.out.println("HeaderReceiver:handlerAge>>>>"+new String(msg,0,msg.length));
}
}
3、测试代码:
@Test
public void rabbitHeader(){
//设置音讯,并且设置header,setHeader("name","hello")别离示意map汇合中的key、value
Message nameMessage =
MessageBuilder.withBody("hello name".getBytes()).setHeader("name","hello").build();
Message ageMessage =
MessageBuilder.withBody("hello 99 age".getBytes()).setHeader("age","99").build();
rabbitTemplate.send(RabbitHeaderConfig.HEADERNAME,null,nameMessage);
rabbitTemplate.send(RabbitHeaderConfig.HEADERNAME,null,ageMessage);
}
查看输入:
扭转setheader中的值查看后果:
Message nameMessage =
MessageBuilder.withBody("hello name".getBytes()).setHeader("name","javaboy").build();
能够看到因为key、value匹配不上只打印了一条音讯。
