spring boot 2.0.3使用Lettuce Redis并配置 pool

依赖的jar包：

        
            org.springframework.boot
            spring-boot-starter-data-redis
        
        
            org.apache.commons
            commons-pool2
            2.6.0
        

RedisTemplate默认提供的序列化器

RedisSerializer redis序列化的接口类

OxmSerializer xml到object的序列化/反序列化

StringRedisSerializer string字符串的序列化/反序列化

JacksonJsonRedisSerializer json到object的序列化/反序列化

Jackson2JsonRedisSerializer json到object的序列化/反序列化

JdkSerializationRedisSerializer java对象的序列化/反序列化
