springboot 中的redis配置（Jedis )（非集群）

1. pom.xml

      <!--redis 相关jar包-->
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-data-redis</artifactId>
   </dependency>
   

2. application.properties

    spring.redis.host= 127.0.0.1
    spring.redis.port= 6379
   

3. config

   	import org.slf4j.Logger;
   	import org.slf4j.LoggerFactory;
   	import org.springframework.beans.factory.annotation.Value;
   	import org.springframework.context.annotation.Bean;
   	import org.springframework.context.annotation.Configuration;
   	import org.springframework.context.annotation.PropertySource;
   	import redis.clients.jedis.JedisPool;
   	import redis.clients.jedis.JedisPoolConfig;
   	
   	@Configuration
   	@PropertySource(value="classpath:bootstrap.properties")
   	public class RedisConfig {
   
       private Logger log = (Logger) LoggerFactory.getLogger(RedisConfig.class);
   
       @Value("${spring.redis.host}")
       private String host;
   
       @Value("${spring.redis.port}")
       private int port;
   
       @Bean
       public JedisPool getJedisPool(){
           log.info("==>初始化jedis连接池");
           JedisPoolConfig config = new JedisPoolConfig();
           JedisPool pool = new JedisPool(config, host, port);
           return pool;
       }
   }
   

4. 在 要用的类中注入：

    	 @Autowired
        private JedisPool jedisPool;
   

5. 方法中使用：

     Jedis redis = jedisPool.getResource();
   
   	redis.set("key值","value");
       redis.lpush("key值","value");
       redis.expire("key值",时间：秒);
   
    //llen  的方法  取出list长度
    redis.llen(phoneNumber + format);
