Description:

Field connectionFactory in com.lee.securityoauth2.config.AuthorizationServerConfig required a bean of type 'org.springframework.data.redis.connection.RedisConnectionFactory' that could not be found.

    - @org.springframework.beans.factory.annotation.Autowired(required=true)

The following candidates were found but could not be injected:
    - Bean method 'redisConnectionFactory' in 'JedisConnectionConfiguration' not loaded because @ConditionalOnClass did not find required class 'redis.clients.jedis.Jedis'
    - Bean method 'redisConnectionFactory' in 'LettuceConnectionConfiguration' not loaded because @ConditionalOnClass did not find required class 'io.lettuce.core.RedisClient'

Action:

Consider revisiting the entries above or defining a bean of type 'org.springframework.data.redis.connection.RedisConnectionFactory' in your configuration.

解决方法： 

• 如果使用lettuce，则添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
 <dependency>
    <groupId>redis.clients</groupId>
    <artifactId>lettuce</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.0</version>
</dependency>

•  如果使用jedis，则添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <exclusions>
       <exclusion>
           <groupId>io.lettuce</groupId>
           <artifactId>lettuce-core</artifactId>
       </exclusion>
   </exclusions>
</dependency>
<dependency>
   <groupId>redis.clients</groupId>
   <artifactId>jedis</artifactId>
</dependency>
