MyFaces CODI - 添加到项目

Question

我正在开发一个 maven JSF Web 应用程序。 我想在一些 @ViewScoped bean 上使用 @PreDestroy，但是这在 JSF 2.0 中是不可能的（或者在页面关闭或重定向时不可能） 我发现 MyFaces CODI 的 @ViewAccessScoped 可能是解决方案，但是我在添加它时遇到了问题。 当我尝试这个时：

<dependency>
    <groupId>org.apache.myfaces.extensions.cdi.bundles</groupId>
    <artifactId>myfaces-extcdi-bundle-jsf20</artifactId>
    <version>1.0.5</version>
</dependency>

编译时出错。

没有依赖项目运行良好。

我附上错误日志：

Answer 1

当我在 JSF 中使用 Spring 时，我正在使用一个巴西框架，该框架使用 myfaces Orchestra 范围作为 Spring 新范围的背景：

• "SameViewed" -> 就像@ViewScope (JSF)
• "AccessScoped" -> 与 ViewAccessScoped 一样

这是一个非常好的图书馆，我没有更多的问题 在我的项目中使用范围。

抱歉，这是葡萄牙语，但如果显示有委托书，我可以翻译或帮助您入门... 葡萄牙语教程的链接：

希望这会有所帮助！ :)
