将 Java WEB、ZK、Spring 项目从非 Maven 迁移到 Maven

Question

我正在迁移到 Netbeans 上的 Maven，这是一个基于 Java 1.7 的旧项目，运行s 在 glassfish 3 上，该项目使用 Hibernate 4.3.1，Spring 3.0 .6，接口部分为ZK 6。

我设法将所有以前的 jar 添加到 POM.xml 我还创建了 beans.xml 文件。所以项目编译没有错误，项目也启动正常，第一页（登录页面）正确打开。在日志中我可以看到所有的数据库访问工作正常，所以域和 businessImpl 也运行ning 正常，但是当我登录时，应该加载的页面无法显示并出现以下错误：

在向未加载页面的 ZK ViewModel 添加额外的日志后，我可以确定错误发生在 ViewModel 的 init() 之后，这意味着当 ZK 尝试评估要显示的信息时，例如在@绑定或@load。这就解释了为什么加载登录页面，它是一个不显示动态信息的静态页面。

所以在迁移过程中我一定错过了一些允许 ZK 和 Srping inter-actuate 的东西？

我预计在迁移过程中我错过了 Spring 或 ZK 的一些配置文件，但仅基于上面显示的错误，我的朋友 Google 并没有太大帮助...... 有什么关于去哪里看的建议吗？

编辑：谢谢鹰！感谢您的评论，我设法更多地确定了问题的根源。我删除了主页的全部内容并加载了它，当然，然后 re-inserting 无论哪个组件一个一个地出现相同的错误，所以基本上，任何 @load 或 @bind 都会触发此错误。现在这个应用程序已经很老了，我有一些最初是在 ZK5 中开发的页面，没有视图模型（即：zul 中没有 apply="org.zkoss.bind.BindComposer"，但是有 "use="ui.Class”在 ZK window header) 中，所以在 zul 中没有任何 @load 或 @bind，这些页面工作完美。所以问题肯定是 ZK 6 没有管理 @load 或 @bind 任何东西.是全局配置问题，是我错误的迁移到MAVEN导致的

编辑2：将项目迁移到 IntelliJ，使用 MAVEN，同样的问题，编译，运行，但包含 @Load 或 @Bind 的 ZK 页面生成相同的错误...

Answer 1

找到解决方案，问题来自 ZK 的 EL 绑定注释，我检查了 pom.xml 版本并发现不一致。即使非 maven 项目在 pom 中指定的 zk 库版本上运行良好，我也将 ZKEL 依赖项更改为更新的依赖项并且它起作用了。感谢 Hawk 让我走上正轨。

Answer 2

您应该添加相同版本的 ZK 相关 jar，例如zkmax、zul、zk 和 zel。由于你使用Maven，如果你只指定zkmax或zkex，Maven会自动包含相同版本的依赖项（如果你不覆盖它）。
