entityManagerFactory bean 是在 jpaContext.xml 中定义的，但编译器会抛出错误。提前致谢。

【问题讨论】：

欢迎来到Stack Overflow。请提供minimal reproducible example。就目前而言，您的问题太长太冗长了。
对于初学者，请停止混合 Spring 版本。你混合了 Spring 3.2.16 和 3.2.0 的 jars（我不是在谈论 Spring Security 依赖项）。
上下文是否加载？如果不尝试 'classpath:*jpaContext.xml'
@MohsanShakir 它仍然给出错误。我有一个 jpaContext。

标签： java spring maven spring-mvc jpa

【解决方案1】：

试试这个配置。你的persistence.xml有错误请分享错误。
