很简单,看我的github的例子就行
2.1导包
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.0.2.RELEASE</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.1.0</version>
</dependency>
2.2配置applicationContext.xml
Spring提供了很多序列化器
Jackson2JsonRedisSerializer
JdkSerializationRedisSerializer
OxmSerializer
StringRedisSerializer
GenericToStringRedisSerializer
GenericJackson2JsonRedisSerializer
<!--redisconfig-->
<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="50" />
<property name="maxActive" value="100" />
<property name="maxWait" value="6000"/>
</bean>
<!--rdis连接工厂-->
<bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="localhost" />
<property name="port" value="6379" />
<property name="poolConfig" ref="poolConfig" />
</bean>
<!--string 和jdk序列化器-->
<bean id="jdkSerializationRedisSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"
/>
<bean id="stringRedisSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer"
/>
<!--配置redisTemplate-->
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="connectionFactory" />
<!--key和value的序列化方式常用string或者jdk-->
<property name="keySerializer" ref="stringRedisSerializer" />
<property name="valueSerializer" ref="stringRedisSerializer" />
</bean>
2.3测试
ApplicationContext
applicationContext = new ClassPathXmlApplicationContext(
"applicationContext.xml");
RedisTemplate
redisTemplate = applicationContext
.getBean(RedisTemplate.class);
2.4 StringRedisTemplete和RedisTemplete的区别
StringRedisTemplete继承RedisTemplete,内部使用string序列化器,所以适合操作key和value都是string的数据
3 Spring中发布订阅
3.1首先提供接收消息的类,它将实现 org.springframework.data.redis.connection.MessageListener 接口,并实现接口定义的方法 public void onMessage(Message message,byte[]pattern)
/*** imports ***/
23. }
3.2.在spring中配置自定义的监听器
<!--配置redis监听器-->
<bean id="messageListener" class="com.zy.listener.RedisMessageListener">
<property name="stringRedisSerializer" ref="stringRedisSerializer"/>
<property name="jdkSerializationRedisSerializer"
ref="jdkSerializationRedisSerializer"/>
</bean>
3.3 要给一个监听容器,在 Spring 中已有类 org.springframework.data.redis.listener.RedisMessageListenerContainer。它可以用于监听 Redis 的发布订阅消息,下面的配置就是为了实现这个功能,读者可以通过注释来了解它的配置要点。
<!--配置redis监听器container-->
<!--配置线程池-->
<bean id="poolTaskScheduler"
class="org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler">
<property name="poolSize" value="3" />
</bean>
<!--配置容器,topic是监听的通道的名称,自定义的-->
<redis:listener-container connection-factory="connectionFactory" task-executor="poolTaskScheduler" topic-serializer="stringRedisSerializer">
<redis:listener ref="messageListener" method="onMessage" topic="chat" serializer="stringRedisSerializer"/>
</redis:listener-container>
3.4 测试,像chat通道发送消息
4 springboot整合redis
4.1新建springboot项目,勾选上redis
4.2配置application.yml
spring:
redis:
host: 127.0.0.1
port: 6379
jedis:
pool:
max-active: 100
max-idle: 10
max-wait: 20000
lettuce:
shutdown-timeout: 1000
4.2 配置redis的配置类
@Configuration
public class RedisConfig {
@Bean
public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
RedisTemplate<String,Object> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(redisConnectionFactory);
redisTemplate.setKeySerializer(stringRedisSerializer());
redisTemplate.setValueSerializer(jdkSerializationRedisSerializer());
return redisTemplate;
}
@Bean
public StringRedisSerializer stringRedisSerializer(){
return new StringRedisSerializer();
}
@Bean
public JdkSerializationRedisSerializer jdkSerializationRedisSerializer(){
return new JdkSerializationRedisSerializer();
}
}
4.3 测试
@SpringBootTest
class SpringbootRedisApplicationTests {
@Autowired
private RedisTemplate<String,Object> redisTemplate;
@Test
void contextLoads() {
redisTemplate.opsForValue().set("myname","zhouyang");
String myname = (String)redisTemplate.opsForValue().get("myname");
System.out.println(myname);
}
}
4.4 配置订阅发布
4.4.1新建类实现MessageListener
public class MyRedisMessageListener implements MessageListener {
@Autowired
private RedisTemplate<String,Object> redisTemplate;
@Override
public void onMessage(Message message, byte[] bytes) {
// 获取消息
byte[] body = message.getBody();
// 使用值序列化器转换
String msgBody = (String) redisTemplate.getValueSerializer()
.deserialize(body);
System.err.println(msgBody);
// 获取 channel
byte[] channel = message.getChannel();
// 使用字符串序列化器转换
String channelStr = (String) redisTemplate.getStringSerializer()
.deserialize(channel);
System.err.println(channelStr);
// 渠道名称转换
String bytesStr = new String(bytes);
System.err.println(bytesStr);
}
}
4.4.2 配置redisConfig,把messageListener和containner放入容器中
@Bean
public MyRedisMessageListener myRedisMessageListener(){
return new MyRedisMessageListener();
}
@Bean
public RedisMessageListenerContainer redisMessageListenerContainer (RedisConnectionFactory redisConnectionFactory){
RedisMessageListenerContainer
redisMessageListenerContainer = new RedisMessageListenerContainer();
redisMessageListenerContainer.setConnectionFactory(redisConnectionFactory);
redisMessageListenerContainer.addMessageListener(myRedisMessageListener(),new PatternTopic("chat"));
return redisMessageListenerContainer;
}
4.4.3测试
@Test
void testPublish() {
redisTemplate.convertAndSend("chat","我是周扬");
}
jedis的使用,spring整合redis,springboot整合redis
