Caused by: java.lang.NoSuchMethodError: org.apache.commons.pool2.impl.GenericObjectPoolConfig.setMax

关键报错如下

Caused by: java.lang.NoSuchMethodError: 
org.apache.commons.pool2.impl.GenericObjectPoolConfig.setMaxWait(Ljava/time/Duration;)V

解决方案1：

这种十有八九就是POM依赖管理出错了，存在某些pom依赖交叉重复的现象！！！
比如我这里的

        <dependency>
            <groupId>org.apache.commonsgroupId>
            <artifactId>commons-pool2artifactId>
            <version>2.10.0version>
        dependency>

和

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-data-redisartifactId>
        dependency>

这俩依赖就是重复的，结果造成重复依赖！！！最后我删除了commons-pool2的依赖解决了问题！！
我的完整pom依赖如下。
