1.起因🤶🤶🤶🤶
redis搭建完成后,准备启动主程序,异常兴奋,结果报错了!!!!
2.究竟是何原因 😭😭😭😭😭
出现一下错误:
- 1.RedisConnectionFactory is required
- 2.Error creating bean with name 'redisTemplate' defined in class path resource [com/xz/config/RedisConfig.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: RedisConnectionFactory is required
- 3.Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'redisTemplate'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'redisTemplate
源码一探究竟

3.一顿操作猛如虎
原本以为自己没有配数据库连接池导致的问题,回去又去添加个连接池~
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId><version>3.1.2</version></dependency>
jedis:pool:max-active: 8max-wait: 1msmax-idle: 4min-idle: 0
这时的我还没有意识到严重性!!!!自信的回去跑主程序~结果还是这个问题!!!!
说明什么????说明与连接池无关 !!!
等等。。。。。之前加入了key序列化配置类,灵机一动,解决了!!!听我娓娓道来~~~
4.so!so!easy嘛
检查配置类时发现没有设置连接工厂,我真是个可爱~
redisTemplate.setConnectionFactory(connectionFactory);
至此问题解决!!!!!
5.强调一波
已经是粗心导致的第好几次错误了!!!!!!
下次在粗心我就是!!咳咳咳~~~,算了,算了
