SpringMVC + JPA +找不到元素'persistence'的聲明

我得到「無法找到聲明的元素'持久性'例外我試過OpenJPA 2.1.1 - Cannot find the declaration of element 'persistence'給出的解決方案，但它不起作用。。我的項目我曾嘗試更新是根據張貼在StackOverflow上其他解決方案 '的persistence.xml'，但沒有運氣SpringMVC + JPA +找不到元素'persistence'的聲明

春天不能加載'persistence.xml'從文件加載列表中刪除它。另一件你正在混合的框架版本從來沒有這樣做。如果你想要奇怪的問題，你正在混合使用Spring 3.2.4,3.1.4和4.0.7。 –

謝謝，將所有的春季版本改爲'3.1.4'已經解決了這個問題。 –

改變所有的春季版本 '3.1.4' 已經解決了這個問題。版本不應混用。
