java - Spring+JPA+MVC(无Maven)创建bean时出错

Question

首先，我真的很抱歉问这个问题，因为我在这里看到了同样的问题( Spring + JPA + MVC - Error creating bean )，但我仍然不知道如何解决我的情况。因为:

• 我对 Spring 非常陌生，我正在很短的时间内完成一个项目。

• 导入的项目使用Spring 2.5.6(非常旧)。所有 jar 文件都保留在“lib”文件夹中，并且不使用 Maven。

当我导入项目时，它显示了这些错误。我从“Spring + JPA + MVC - Error creating bean”学到的是我需要解决jar文件之间的冲突。 但是即使我花了一整天的时间来完成这个小任务，我仍然不知道需要更改哪些 jar 文件。

这是我的“lib”项目的图片:/image/xAg5v.png

我真的很感谢任何帮助。

Answer 1

从堆栈跟踪来看，看起来不像是冲突的 JAR 问题，但似乎存在问题

ssel.banking.domain.Account

检查映射到“名称”列的字段不超过一个。值得检查父类/子类以及名称为“name”的属性。

如果上述情况不属实，发布 ssel.banking.domain.Account 的内容可能会有所帮助。

问题的核心是:

org.hibernate.MappingException: Duplicate property mapping of name found in ssel.banking.domain.Account
