我得到的原因是：java.lang.NoSuchMethodError：javax.persistence.JoinColumn.foreignKey（）Ljavax / persistence / ForeignKey这个异常

Question

基本上我的pom结构依赖关系看起来像

import subprocess
import time

tmp=subprocess.call('clear', shell=True) # 'cls' in windows
keyword = input(" Please enter the word you want the person to guess")
lives = int(input("How many lives would you like to have?"))
print ("There are ", len(keyword), "letters in the word")

time.sleep(2)

我正在尝试ehCache第二级示例的示例，我的项目结构看起来像

我将root context.xml声明为

您可以通过执行System.out.println(getClass().getResource("/javax/persistence/JoinColumn.class"));

来查看您使用的是哪一个
