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

【问题标题】：Migrating Java WEB, ZK, Spring project from non Maven to Maven将 Java WEB、ZK、Spring 项目从非 Maven 迁移到 Maven
【发布时间】：2019-05-03 19:52:30
【问题描述】：

我正在迁移到 Netbeans 上的 Maven，这是一个基于 Java 1.7 并在 glassfish 3 上运行的旧项目，该项目使用 Hibernate 4.3.1、Spring 3.0.6 和 ZK 6 作为接口部分。

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，我可以看到所有数据库访问工作正常，因此域和 businessImpl 也运行良好，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：

在未加载页面的 ZK ViewModel 添加额外日志后，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 @bind或@load。这就解释了为什么登录页面加载，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 交互的东西？

我希望在迁移中我错过了 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... 有什么建议去哪里看吗？

编辑： 谢谢鹰！感谢您的 cmets，我设法确定了更多问题的根源。我删除了主页的全部内容并加载了它，当然，然后一个接一个地重新插入我得到相同错误的任何组件，所以基本上，任何@load 或@bind 都会触发此错误。现在，由于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：在 zul 中没有 apply="org.zkoss.bind.BindComposer"，但是有 "use="ui.Class " 在 ZK 窗口标题中），因此在 zul 中没有任何 @load 或 @bind ，这些页面可以完美运行。所以问题肯定是 ZK 6 没有管理到 @load 或 @bind 任何东西。这是一个全局配置问题由于我错误地迁移到 MAVEN。

编辑2： 将项目迁移到 IntelliJ，使用 MAVEN 和相同的问题，编译，运行，但包括 @Load 或 @Bind 的 ZK 页面会产生相同的错误...

【问题讨论】：

  • 根据堆栈跟踪，它与解析数据绑定表达式有关。如果您可以找到导致错误的表达式，那将很有帮助。您可以一个一个地删除数据绑定，直到找到有问题的那个。
  • 如果我发布 web.xml、applicationContext.xml 和 dispatcher-servlet.xml 会有帮助吗？它们适用于非 Maven 项目，但在 Maven 上下文中运行时可能需要对其进行编辑...

标签： spring maven spring-mvc java-7 zk


【解决方案1】：

解决方案发现，问题来自 ZK 的 EL 绑定注释，我检查了 pom.xml 的版本，发现不一致。即使非 maven 项目在 pom 中指定的 zk 库版本运行良好，我将 ZKEL 依赖项更改为更新的依赖项并且它可以工作。感谢 Hawk 让我走上正轨。

【讨论】：

    【解决方案2】：

    您应该添加具有相同版本的 ZK 相关 jar，例如zkmax、zul、zk 和 zel。由于你使用的是 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）。

    请参考https://www.zkoss.org/wiki/ZK_Installation_Guide/Setting_up_IDE/Maven/Resolving_ZK_Framework_Artifacts_via_Maven#ZK_EE
