我读过所有关于这个职位,我能找到的,但我似乎无法让过去这个错误让我的Maven的Spring MVC的Web应用程序的工作。 我刚刚得到一个HTTP状态500,当我访问本地主机或任何在我的控制器中指定的URI的。
从我的理解,出现问题是因为比在运行时使用编译时使用更高的JDK。 但似乎对我来说,所有引用到JDK或JRE的是在我的情况一样。 (1.8)根据这样看来,我需要用java 1.8是这个堆栈溢出后,所以我不知道是什么问题:
如何解决java.lang.UnsupportedClassVersionError错误:不支持MAJOR.MINOR版本
步骤我已经采取了
我完全相信我的pom.xml文件引用在java 1.8。 在的IntelliJ:在编译器设置我设定的目标字节码的版本是1.8。 在Maven的设置进口商的JDK被设置为Java 1.8,因为是亚军。 在项目结构工程SDK被设置为Java 1.8和项目语言级别设置为8。我也查java.com并确认在Internet Explorer中运行Java版本是相同的版本1.8作为我的JDK和JRE。 我也确信,在我的电脑上我的PATH变量指向正确的JDK。 如在黑暗中拍摄,我也试图改变所有的引用用java 1.7,但在部署后,仍然得到了同样的错误。
下面我列出我的pom.xml文件和错误的堆栈跟踪。 与往常一样,感谢您的时间和帮助!
