遇到的问题
报错：
The called method's class, org.apache.commons.pool2.impl.GenericObjectPoolConfig, is available from the following locations:jar:file:/D:/software/maven/mavenRepository/org/apache/commons/commons-pool2/2.9.0/commons-pool2-2.9.0.jar!/org/apache/commons/pool2/impl/GenericObjectPoolConfig.class
Correct the classpath of your application so that it contains compatible versions of the classes org.springframework.boot.autoconfigure.data.redis.LettuceConnectionConfiguration$PoolBuilderFactory and org.apache.commons.pool2.impl.GenericObjectPoolConfigpom配置：
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.12</version><relativePath/> <!-- lookup parent from repository --></parent><dependencies><!--redis依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><!-- redis依赖commons-pool 这个依赖一定要添加 --><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId><version>2.9.0</version></dependency><dependencies>
原因：
commons-pool2版本与redis版本不一致导致的
解决方法
方法1：
选择redis跟commons-pool2合适的版本：
<dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId><version>2.11.1</version></dependency>
当时去掉commons-pool2依赖也可以
spring-boot-starter-parent版本2.7.12对应commons-pool2版本2.11.1
方法2：
切换springboot版本：
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.4.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><dependencies><!--redis依赖--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><!-- redis依赖commons-pool 这个依赖一定要添加 --><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId></dependency><dependencies>
spring-boot-starter-parent版本2.3.4.RELEASE对应的commons-pool2版本是2.8.1
redis不指定版本就跟随spring-boot-starter-parent指定的版本
