各版本lettuce spring集成流程(连接池、哨兵配置)
spring-data-2与其上一个版本1.8是一个分水岭，2.0用的是io.lettuce:lettuce-core,2.0之前的spring-data用的是biz.paluch.redis:lettuce
spring-data-2.0以上版本配置
spring-data-redis版本2.0.9.RELEASE
io.lettuce:lettuce-core版本5.0.4.RELEASE
依赖：
io.lettuce
lettuce-core
5.0.4.RELEASE
org.springframework.data
spring-data-redis
2.0.9.RELEASE
org.apache.commons
commons-pool2
2.6.0
最终目标为：StringRedisTemplate或者RedisTemplate
需要 ： RedisConnectionFactory
其实现为 ： LettuceConnectionFactory
因实现sentinel，所以需要构造参数：
1、RedisSentinelConfiguration，其配置sentinel-master和ip:host
2、LettuceClientConfiguration，可其配置连接池以及ssl等相关参数（使用其子接口LettucePoolingClientConfiguration）
LettucePoolingClientConfiguration.可通过static方法使用builder模式创建：
LettucePoolingClientConfiguration.builder().poolConfig(pool).build();pool类型GenericObjectPoolConfig为common-pool2线程池
实现代码：
bean配置（连接池，spring-template等）
/**

@Configuration
@PropertySource(value = {"classpath:redis.properties"})
@ComponentScan(basePackages = "com")
public class RedisClientConfiguration {

stringRedisTemplate.setConnectionFactory(redisConnectionFactory);

poolConfig.setMaxTotal(commonPool2Properties.getMaxTotal());
//todo 其他配置
return poolConfig;

哨兵信息配置

连接池信息配置

# todo 其他线程池配置spring-data-2.0以下版本配置
spring-data-redis版本1.8.7.RELEASE
io.lettuce:lettuce-core版本4.2.2.RELEASE
依赖：
biz.paluch.redis
lettuce
4.2.2.Final
org.springframework.data
spring-data-redis
1.8.7.RELEASE
org.apache.commons
commons-pool2
2.6.0
最终目标为：StringRedisTemplate或者RedisTemplate
需要 ： RedisConnectionFactory
其实现为 ： LettuceConnectionFactory
需要构造参数：
LettucePool接口，其默认实现为DefaultLettucePool。
DefaultLettucePool可接收RedisSentinelConfiguration类型构造参数，然后可以为其设置GenericObjectPoolConfig用于配置common-pool2的连接池。
spring-data-2.0.x与之前版本还有一个区别就是ssl等配置放到了LettuceConnectionFactory中。
直接xml实现完整配置
${lettuce.sentinel.node1}
${lettuce.sentinel.node2}
${lettuce.sentinel.node3}
