spring4 hibernate5 struts2 整合时出现异常该怎么解决，求各位大神帮帮忙

org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'sessionFactory' defined in class path resource
[applicationContext.xml]: Instantiation of bean failed;
nested exception is org.springframework.beans.BeanInstantiationException:
Failed to instantiate [org.springframework.orm.hibernate5.LocalSessionFactoryBean]:
No default constructor found; nested exception is
java.lang.UnsupportedClassVersionError: org/hibernate/cfg/Configuration
: Unsupported major.minor version 52.0 (unable to load class
org.hibernate.cfg.Configuration)

别人说是jdk版本不对，我都换过了，还是没有用，是不是jar包的问题呢?

你的SQL驱动用的mysql的，你看下你的db配置是不是有问题。我之前遇到的问题就是因为用的SQL配置与驱动JAR包不一直导致的

代码的编译版本不对，不是jdk版本
