简介: MyEclipse中JDK版本不匹配解决方法

一、问题表现形式


昨天刚搭好SpringMVC框架,今天早上试着去连接数据库,结果失败了,紧接着捣鼓了Maven,之后运行出现了一下问题,这是在网页中显示的。

二、解决方法


1.打开Window->Preferences->Java->Installed JREs

2.把当前较高的JDK版本卸了(Remove)

3.重启MyEclipse,开启服务器,发现没有错误了。

三、总结


JDK的版本尽量选择最稳定的,不要选择太新的,因为你的其他的一些包可能更新的比较慢,他们只支持早期的JDK。但是,也不要太旧,因为有很多BUG。
