项目 伙伴匹配项目无法正确引入 spring-boot-starter-data-redis 和 spring-session-data-redis 问题描述：在做伙伴匹配系统 5 时，无法正确引入 spring-boot-starter-data-redis 和 spring-session-data-redis，引入依赖，刷新 maven 启动项目后，项目报错 Error creating bean with name 'redisConnectionFactory' 已经尝试过的方法包括： 1. 在 Application启动类上添加 `@EnableCaching` 注解 2. 更换 spring-boot-starter-data-redis 版本为3.2.1，2.4.0，2.6.4 等（我的 springboot 版本为2.2.5.RELEASE） 3. 添加连接池依赖 commons-pool2 4. 把配置文件中redis配置中的jedis改为lettuce 以上方法均告失效。 pom 依赖配置： ```pom <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> <version>2.4.0</version> </dependency> <!-- redis --> <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-redis --> <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> <!--连接池依赖--> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-pool2</artifactId> <version>2.8.0</version> </dependency> ``` Application. Yml 文件： ```yml session: timeout: 86400 store-type: redis redis: port: 6379 host: localhost database: 0 ``` 完整报错信息： ``` Error starting ApplicationContext.
