表示t您已经用Java 8构建了Jars，但正试图以较低版本运行该应用程序。



从我在别处看到的情况来看，您可能需要切换到一个更新版本的javassist（这会引发错误），因为您使用的版本与Java 8不兼容。


I am following http://spring.io/guides/tutorials/data/3 ; I am not sure what I did wrong, but I keep on getting exceptions that I don't understand. I tried searching for questions with the same exceptions to no avail.

I hope someone could point me to the right source, or help me in this predicament.

解决方案

The error:

invalid constant type: 18

Indicates that you have built the Jars with Java 8, but are attempting to run the application in a lower version.

From what I have seen elsewhere, you probably need to switch to a newer version of javassist (which is raising the error), as the version you are using is not compatible with Java 8.
