多模块 spring 休眠，访问 dao 有困难，需要创建 spring bean xml？

Question

我制作多模块应用程序（vaadin，spring，休眠）我在访问 DAO（或模型，通常在持久性模块中具有持久性）时遇到很大问题

我需要在 core 中创建 spring xml bean 定义或在 中创建 spring bean ]web（在 applicationContext.xml 中）?

我收到错误：

services/TestService.java:[3,11] package dao does not exist
cannot find symbol  symbol:   class User
Generally core don't see persistence class

一般来说，我有 3 个模块：

核心
坚持
网络

核心pom.xml

Answer 1

问题是，maven项目persistence是版本1.0.0-SNAPSHOT。但是 core 依赖于 1.0-SNAPSHOT ，它要么是一个从未存在的版本，要么是一些旧版本丢失了一些文件。

Answer 2

问题通过评论@Vlasec 解决。

I noticed one problem in your XML. You are asking for persistence 1.0-SNAPSHOT, but your current version is 1.0.0-SNAPSHOT. That means you either get an older version, or you could also get no library at all if you never had 1.0-SNAPSHOT version. – Vlasec Nov 9 at 10:12

那是我的错，这真是一件愚蠢的事情！谢谢！
