我要迁移到Netbeans上的Maven，这是一个基于Java 1.7的老项目，该项目运行在glassfish 3上，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中，并且还创建了beans.xml文件。因此，项目编译没有错误，项目也开始正常运行，并且第一页（登录页面）正确打开。在日志中，我可以看到所有数据库访问均正常运行，因此domains和businessImpl也运行良好，但是当我登录时，应加载的页面无法显示，并显示以下错误：

在未加载页面的ZK ViewModel中添加其他日志后，我可以确定该错误恰好发生在ViewModel的init（）之后，这意味着ZK尝试评估要显示的信息，例如@bind或@load。这就解释了为什么加载登录页面，它是一个静态页面而不显示动态信息。
所以在迁移过程中，我一定错过了允许ZK和Srping交互操作的东西？
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... 关于在哪里看有什么建议吗？
编辑： 谢谢霍克！感谢您的评论，我设法确定了问题的根源。我删除了主页的全部内容，然后加载了它，然后再逐个重新插入任何组件，但我遇到了相同的错误，因此，基本上，任何@load或@bind都会触发此错误。现在，由于该应用程序已经很老了，所以我有一些页面最初是在ZK5中开发的，没有视图模型（即：zul中没有apply =“ org.zkoss.bind.BindComposer”，但带有“ use =” ui.Class在ZK窗口标头中），因此在zul中没有任何@load或@bind时，这些页面就可以正常工作。因此，问题肯定是ZK 6无法管理@load或@bind任何东西。这是全局配置问题由于我不正确地迁移到MAVEN。
EDIT2： 使用MAVEN将项目迁移到IntelliJ，并且编译并运行相同的问题，但是ZK页面（包括@Load或@Bind）会产生相同的错误...

解决方案已找到，问题来自ZK的EL绑定注释，我检查了pom.xml中的版本，发现不一致。即使non maven项目在pom中指定的zk库版本运行良好，我也将ZKEL依赖项更改为较新的版本，并且它起作用了。感谢霍克使我步入正轨。
答案 1 :(得分：0)
您应添加具有相同版本的ZK相关罐子，例如zkmax，zul，zk和zel。由于您使用的是Maven，因此，如果您仅指定zkmax或zkex，则Maven将自动包括相同版本的依赖项（如果您不覆盖它的话）。
