redis消息发布与订阅

一、spring boot+maven环境：

1.pom.xml:

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

2.application.properties:

    # database name
    spring.redis.database=9
    # server host1
    spring.redis.host=#####
    # server password
    spring.redis.password=#####
    #connection port
    spring.redis.port=#####
    # pool settings ...
    spring.redis.pool.max-idle=100
    spring.redis.pool.min-idle=0
    spring.redis.pool.max-active=300
    spring.redis.pool.max-wait=1000

3.消息发布：

@SpringBootApplication
public class Application extends SpringBootServletInitializer{

   @Bean
   StringRedisTemplate template(RedisConnectionFactory connectionFactory) {
   return new StringRedisTemplate(connectionFactory);
   }

/**
* 启动入口
* May 9, 2017
*/
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);

StringRedisTemplate template = ctx.getBean(StringRedisTemplate.class);
// 组装数据
JSONObject data = new JSONObject();
data.put("content", "本地测试");
// 推送消息（sync_message为发送的消息通道）
template.convertAndSend("sync_message", data.toString());
System.out.println(" 消息发送完毕 ");
}
}

4.监听器（订阅者）配置：

@Configuration
public class RedisConfig {

@Bean
RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory,
MessageListenerAdapter listenerAdapter) {

RedisMessageListenerContainer container = new RedisMessageListenerContainer();
container.setConnectionFactory(connectionFactory);
//订阅了一个叫 sync_message 的通道
container.addMessageListener(listenerAdapter, new PatternTopic("sdk_sync_message"));
//这个container 可以添加多个 messageListener
return container;
}

@Bean
MessageListenerAdapter listenerAdapter(MessageReceiver receiver) {
//这个地方是给messageListenerAdapter 传入一个消息接受的处理器，利用反射的方法调用“receiveMessage”
return new MessageListenerAdapter(receiver, "receiveMessage");
}
}

5.处理订阅的信息：

@Component
public class MessageReceiver {
/**接收消息的方法*/
public void receiveMessage(String message){
System.out.println(" 接收消息 ==================" + message);
}
}

二、没有使用spring boot的maven环境：

1.pom.xml:

<dependency>
       <groupId>redis.clients</groupId>
       <artifactId>jedis</artifactId>
       <version>2.9.0</version>
       </dependency>
<dependency>
       <groupId>org.springframework.data</groupId>
       <artifactId>spring-data-redis</artifactId>
       <version>1.8.8.RELEASE</version>
       </dependency>

2.redis.properties：

    redis.host=####
    redis.port=####
    redis.pass=####
    redis.timeout=5000
    redis.maxActive=300
    redis.maxIdle=100
    redis.maxWait=1000
    redis.testOnBorrow=true
    redis.default.db=9

3.applicationContext.xml（订阅者配置）：

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
   <property name="locations">
   <list>
               <value>classpath:redis.properties</value>
   </list>
   </property>
   </bean>

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
       <property name="maxTotal" value="${redis.maxActive}" />
<property name="maxIdle" value="${redis.maxIdle}" />
<property name="maxWaitMillis" value="${redis.maxWait}" />
<property name="testOnBorrow" value="${redis.testOnBorrow}" />
   </bean>
   
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
       <property name="usePool" value="true"></property>
<property name="hostName" value="${redis.host}" />
<property name="port" value="${redis.port}" />
<property name="password" value="${redis.pass}" />
<property name="timeout" value="${redis.timeout}" />
<property name="database" value="${redis.default.db}" />
<constructor-arg index="0" ref="jedisPoolConfig" />
   </bean>
<bean id="stringRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory" />
</bean>

<bean id="sdkListener" class="com.jf.service.api.sdkMessage.SdkRedisMessageHandler" />

<redis:listener-container connection-factory="jedisConnectionFactory">
       
           
       <redis:listener ref="sdkListener" method="sdkMessage" topic="sync_message" />
   </redis:listener-container>

4.SdkRedisMessageHandler.java(处理订阅的信息)

@Component
public class SdkRedisMessageHandler {

    public void sdkMessage(String message) {
       System.out.println(" 公会助手接收sdk的redis消息 ==================" + message);
   }

}
