APPLICATION FAILED TO START

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.boot.autoconfigure.data.redis.LettuceConnectionConfiguration$PoolBuilderFactory.getPoolConfig(LettuceConnectionConfiguration.java:188)

The following method did not exist:

    org.apache.commons.pool2.impl.GenericObjectPoolConfig.setMaxWait(Ljava/time/Duration;)V

The calling method's class, org.springframework.boot.autoconfigure.data.redis.LettuceConnectionConfiguration$PoolBuilderFactory, was loaded from the following location:

    jar:file:/C:/Users/Hoga/.m2/repository/org/springframework/boot/spring-boot-autoconfigure/2.6.4/spring-boot-autoconfigure-2.6.4.jar!/org/springframework/boot/autoconfigure/data/redis/LettuceConnectionConfiguration$PoolBuilderFactory.class

The called method's class, org.apache.commons.pool2.impl.GenericObjectPoolConfig, is available from the following locations:

    jar:file:/C:/Users/Hoga/.m2/repository/org/apache/commons/commons-pool2/2.6.0/commons-pool2-2.6.0.jar!/org/apache/commons/pool2/impl/GenericObjectPoolConfig.class

The called method's class hierarchy was loaded from the following locations:

    org.apache.commons.pool2.impl.GenericObjectPoolConfig: file:/C:/Users/Hoga/.m2/repository/org/apache/commons/commons-pool2/2.6.0/commons-pool2-2.6.0.jar
    org.apache.commons.pool2.impl.BaseObjectPoolConfig: file:/C:/Users/Hoga/.m2/repository/org/apache/commons/commons-pool2/2.6.0/commons-pool2-2.6.0.jar
    org.apache.commons.pool2.BaseObject: file:/C:/Users/Hoga/.m2/repository/org/apache/commons/commons-pool2/2.6.0/commons-pool2-2.6.0.jar

Action:

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.GenericObjectPoolConfig

 

 

解决问题：

引入spring2.X集成redis所需common-pool2依赖中，把version删了。

 

 修改完成重新启动：不报错 

访问成功

 

附上redis所需的依赖
