spring-boot 2.x 整合redis 并解决ClassNotFoundException: io.netty.util.internal.logging.InternalLoggerFact

(1)、引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-all</artifactId>
    <version>4.1.48.Final</version>
</dependency>

第二个依赖缺少可能提示：

ClassNotFoundException: io.netty.util.internal.logging.InternalLoggerFactory

(2)、配置redis信息

application.properties中加载redis配置文件

# redis config
spring.profiles.include=redis

创建redis配置文件application-redis.properties

### redis config
spring.redis.host=192.168.0.35
spring.redis.port=6379
spring.redis.password=123456

(3)、注入redis

@Autowired
private  StringRedisTemplate  redisTemplate;

(4)、操作redis

// 获取authorization
String authorization = x2Service.getAuthorization();
// 保存authorization到redis
redisTemplate.opsForValue().set(tokenRedisKey, authorization);

// 获取authorization
String authorization = (String) redisTemplate.opsForValue().get(tokenRedisKey);

百度教程虽然多，但是2.X都有问题，缺少依赖会报错ClassNotFoundException: io.netty.util.internal.logging.InternalLoggerFactory，折腾一个上午。
