简介: Bean method ‘redisConnectionFactory‘ not loaded because @ConditionalOnClass did not find required c

一、背景描述

项目技术:Spring boot (v2.0.0.RELEASE) + Mybatis plus (3.1.1) + Spring Session (2.0.2.RELEASE)

在引入Spring session

Parameter 1 of method sessionRepositoryFilterRegistration in org.springframework.boot.autoconfigure.session.SessionRepositoryFilterConfiguration required a bean of type 'org.springframework.data.redis.connection.RedisConnectionFactory' that could not be found.
  - Bean method 'redisConnectionFactory' not loaded because @ConditionalOnClass did not find required classes 'org.apache.commons.pool2.impl.GenericObjectPool', 'redis.clients.jedis.Jedis'
  - Bean method 'redisConnectionFactory' not loaded because @ConditionalOnClass did not find required class 'io.lettuce.core.RedisClient'

二、原因分析

根据错误日志

Bean method ‘redisConnectionFactory’ not loaded because @ConditionalOnClass did not find required class ‘io.lettuce.core.RedisClient’ 得出未加载Bean方法“redisConnectionFactory”,因为@ConditionalOnClass未找到所需的类。

三、解决方案

3.1 添加spring-boot-starter-data-redis的依赖

~~~~

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-redis</artifactId>
      <version>2.0.0.RELEASE</version>
</dependency>

3.2 添加jedis依赖

<dependency>
   <groupId>redis.clients</groupId>
   <artifactId>jedis</artifactId>
   <version>3.0.1</version>
</dependency>

完结!
