具体情况

昨天使用SSM整合Redis，发现突然一直报该错

BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource

java.lang.NoSuchMethodError: org.springframework.aop.framework.AopProxyUtils.getSingletonTarget(Ljava/lang/Object;)Ljava/lang/Object;

解决方案

NoSuchMethodError：https://blog.csdn.net/wypblog/article/details/102951861

错误原因：应用程序直接或间接依赖了同一个类的多个版本，并且在运行时执行了缺少方法的版本。

1.首先：我们先通过该路径查看是否存在该方法

从下图看到它是存在的

2.再看输出目录详情

果然问题出在应用程序直接或间接依赖了同一个类的多个版本

3.将spring版版本改为5.2.9.RELEASE（spring-data-redis对应依赖版本），删除输出目录Target，重启项目，恢复正常
