如果你只需要使用基本的redis配置，那么使用如下配置类即可，spring boot会自动扫描redis的基本配置，但是有一项要注意那就是password，如果你在配置文件中设置了password，那么就必须在配置类中手工注入JedisConnectionFactory中，否则会在启动过程中报NOAUTH Authentication required.;：

    @Bean  
    public JedisConnectionFactory redisConnectionFactory() {  
            JedisConnectionFactory factory = new JedisConnectionFactory();  
            factory.setHostName(host);  
            factory.setPort(port); 
            factory.setPassword(password);
            factory.setTimeout(timeout); //设置连接超时时间  
            
            //连接池配置
            JedisPoolConfig poolConfig = new JedisPoolConfig();
            poolConfig.setMinIdle(minIdle);
            poolConfig.setMaxIdle(maxIdle);
            poolConfig.setMaxTotal(maxTotal);
            poolConfig.setMaxWaitMillis(maxWait);
            
            factory.setPoolConfig(poolConfig);
            return factory;  
    }

JedisPoolConfig config = new JedisPoolConfig();
 
//连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true
config.setBlockWhenExhausted(true);
 
//设置的逐出策略类名, 默认DefaultEvictionPolicy(当连接超过最大空闲时间,或连接数超过最大空闲连接数)
config.setEvictionPolicyClassName("org.apache.commons.pool2.impl.DefaultEvictionPolicy");
 
//是否启用pool的jmx管理功能, 默认true
config.setJmxEnabled(true);
 
//MBean ObjectName = new ObjectName("org.apache.commons.pool2:type=GenericObjectPool,name=" + "pool" + i); 默 认为"pool", JMX不熟,具体不知道是干啥的...默认就好.
config.setJmxNamePrefix("pool");
 
//是否启用后进先出, 默认true
config.setLifo(true);
 
//最大空闲连接数, 默认8个
config.setMaxIdle(8);
 
//最大连接数, 默认8个
config.setMaxTotal(8);
 
//获取连接时的最大等待毫秒数(如果设置为阻塞时BlockWhenExhausted),如果超时就抛异常, 小于零:阻塞不确定的时间,  默认-1
config.setMaxWaitMillis(-1);
 
//逐出连接的最小空闲时间 默认1800000毫秒(30分钟)
config.setMinEvictableIdleTimeMillis(1800000);
 
//最小空闲连接数, 默认0
config.setMinIdle(0);
 
//每次逐出检查时 逐出的最大数目 如果为负数就是 : 1/abs(n), 默认3
config.setNumTestsPerEvictionRun(3);
 
//对象空闲多久后逐出, 当空闲时间>该值 且 空闲连接>最大空闲数 时直接逐出,不再根据MinEvictableIdleTimeMillis判断  (默认逐出策略)   
config.setSoftMinEvictableIdleTimeMillis(1800000);
 
//在获取连接的时候检查有效性, 默认false
config.setTestOnBorrow(false);
 
//在空闲时检查有效性, 默认false
config.setTestWhileIdle(false);
 
//逐出扫描的时间间隔(毫秒) 如果为负数,则不运行逐出线程, 默认-1
config.setTimeBetweenEvictionRunsMillis(-1);
