一个轻量级的 redis client ，基于 jedis 进行的友好封装。（就这样描述先...）
<dependency>
<groupId>org.noear</groupId>
<artifactId>redisx</artifactId>
<version>1.6.3</version>
</dependency>
test.rd1:
server: localhost:6379
db: 1
password: 123456
可配置属性参考:
| 属性 | 示例 | 说明 |
|---|---|---|
| server | "localhost:6379" | 地址，"localhost:6379,localhost:6380" -集群模式 |
| db | 1 | 库号，集群模式无效 |
| password | "123456" | 密码 |
| user | "user" | 账号，redis 6.x 新加 |
| maxTotal | 200 | 最大连接数 |
| maxIdle | 200 | 最大空闲数 |
| maxWaitMillis | 3000 | 最大建立连接等待时间 |
| maxAttempts | 5 | 最大重试，集群模式有效 |
| connectionTimeout | 3000 | 连接超时 |
| socketTimeoutMillis | 2000 | Socket超时 |
| serializer | "xxx.SerializerImpl" | 指定自定义序列化实现（一般不指定，用默认的） |
