迁移到JSF 2.3，MyFaces初始化问题 [英] Migrating to JSF 2.3, Problems with MyFaces Initialization
问题描述
我正在升级一个由"common"和"myapp"两个项目组成的应用程序.我现在将其升级到 JSF 2.3(MyFaces)和 Primefaces 7 ，但我不知道如何克服初始化失败的问题.
I'm upgrading an application comprised of two projects, "common" and "myapp". I'm now upgrading it to JSF 2.3 (MyFaces) and Primefaces 7, and I can't figure out how to get past a failure in initialization.
我应该注意，还有很多其他变化.这两个项目都已成功升级到 OpenJDK 11 ， Tomcat 9 ，并已使用 Maven .并且随着对JSF 2.3的更改，不再支持托管bean来支持JAVA的CDI API，而默认情况下，JAVA 11中不再支持它. > DeltaSpike 1.9.1 .尽管有所有这些动态的部分，该应用程序仍可以正常工作以更新JSF，因此我认为问题出在这里.
I should note that there've been a lot of other changes as well. Both projects had been successfully upgraded to OpenJDK 11, Tomcat 9, and to using Maven. And with the change to JSF 2.3, managed beans are no longer supported in favor of JAVA's CDI API, which inconveniently is longer supported by default in JAVA 11. So I've pulled in OpenWebBeans 2.0 and DeltaSpike 1.9.1. Despite all these moving parts, the application was working up to the point of updating JSF, so I believe the issue is located there.
在这一点上，我有两种可能的配置，都失败了.使用一种配置，我会收到此错误:
At this point I have two possible configurations, both failing. With one configuration I get this error:
[main] ERROR [Catalina].[localhost].[/myapp] - StandardWrapper.Throwable
No Factories configured for this Application. This happens if the faces-initialization
does not work at all - make sure that you properly include all configuration settings
necessary for a basic faces application and that all the necessary libs are included. Also
check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some
special web-containers which do not support registering context-listeners via TLD files
and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
因此，显而易见的解决方案是添加侦听器，但随后我得到了:
So, obvious solution was to add the listener, but then I get this:
[main] ERROR myfaces.config.FacesConfigurator - No ManagedBeanDestroyerListener instance
found, thus @PreDestroy methods won't get called in every case. This instance needs to be
published before configuration is started.
这似乎是一个排序问题，其中在Faces配置开始之前，StartupServletContextListener没有发布ManagedBeanDestroyerListener.但是，在我的研究中，我读到不需要StartupServletContextListener，因为它是从JSF jars中的TLD自动加载的.
This seems like a sequencing issue where the StartupServletContextListener isn't publishing the ManagedBeanDestroyerListener before the Faces configuration begins. However, in my research I read that the StartupServletContextListener should not be required as it is automatically loaded from a TLD in the JSF jars.
有人知道这是怎么回事吗?我该如何克服?
Anyone understand what's going on here? How can I get past this?

推荐答案
[2020年1月3日更新:我正在更新此条目，以删除一些错误的建议.具体来说，将faces-config.xml重命名为standard-faces-config.xml会阻止MyFaces正确初始化.]
[Update 3-Jan-2020: I'm updating this entry to remove some bad advice. Specifically, renaming faces-config.xml to standard-faces-config.xml prevented MyFaces from initializing properly.]
我已经解决了大多数问题.有几个因素干扰了我的项目.
I've resolved most of my issues. There were several components interfering with my project.
对Eclipse来说，Maven是一个新手，这是一个痛苦的教训，要知道我确实必须确保自己重新运行Maven构建并清理我的部署文件夹，以便实际上执行更改.之后，这里是我发现并修复的要点.
Being new to Maven with Eclipse, it was a painful lesson to learn I really had to make sure I was re-running the Maven builds and cleaning out my deployment folders so that I was actually executing my changes. After that, here are the essentials of what I found and fixed.
- 显然，当处理另一个引用的项目时，m2e无法正确处理测试jar.因此，使用
<classifier>tests</classifier>或<type>test-jar</type>的<dependency>块将不起作用，但是以下内容会将测试源复制到相关项目中进行编译. (确保适当地编辑<source>值，并在Eclipse中运行的Maven中启用m2e配置文件)
- Apparently, when dealing with a second referenced project, m2e doesn't handle test jars correctly. So a
<dependency>block using<classifier>tests</classifier>or<type>test-jar</type>won't work, but the following will copy the test sources over to the dependent project for compilation. (be sure to edit the<source>value as appropriate, and enable the m2e profile in the Maven run in Eclipse)
<profiles>
<profile>
<id>m2e</id>
<activation>
<property>
<name>m2e.version</name>
</property>
</activation>

org.apache.myfaces.core:myfaces-bundle只是org.apache.myfaces.core:myfaces-api和org.apache.myfaces.core:myfaces-impl组合在一起的一个包装.包括一个/或一个，但不能两个都包括. (我收到的建议是使用单独的软件包，而不是捆绑包.)org.apache.myfaces.core:myfaces-bundleis justorg.apache.myfaces.core:myfaces-apiandorg.apache.myfaces.core:myfaces-implcombined into one package. Include either/or but not both. (The recommendation I received was to use the separate packages, not the bundle.)尽管我在Apache上读过什么，但DeltaSpike并没有使启动CDI(OpenWebBeans)变得更加容易，因此我将其删除了.似乎注册OpenWebBeans启动侦听器就足够了(见下文).
Despite what I'd read at Apache, DeltaSpike does not make startup CDI (OpenWebBeans) any easier, so I removed it. It seems that registering the OpenWebBeans startup listener was sufficient (see below).
cobertura(
org.codehaus.mojo:cobertura-maven-plugin)不支持JDK 11.人们推荐使用JaCoCo#67代替它.JDK 11 is not supported by cobertura (
org.codehaus.mojo:cobertura-maven-plugin). People recommended JaCoCo #67 in its place.
从托管Bean切换到CDI时，web.xml中需要以下几行.不建议使用托管Bean，但默认情况下仍启用它.
In switching from managed beans to CDI, the following lines are necessary in web.xml. Managed beans, while deprecated, still defaults to being enabled.
<context-param> <param-name>org.apache.myfaces.SUPPORT_MANAGED_BEANS</param-name> <param-value>false</param-value> </context-param> <context-param> <param-name>org.apache.myfaces.annotation.USE_CDI_FOR_ANNOTATION_SCANNING</param-name> <param-value>true</param-value> </context-param>以下是我当前正在使用的侦听器(及其顺序):
And the following are the listeners (and their order) that I'm currently using:
<listener> <listener-class>com.company.application.app.MyApplicationContextListener</listener-class> </listener> <listener> <listener-class>org.apache.webbeans.servlet.WebBeansConfigurationListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> </listener>
不做我做的事. 不要创建一个
standard-faces-config.xml文件.这会阻止Faces正确初始化. [找不到公共项目的faces-config.xml文件，并且重命名似乎可以解决问题. ] 这个错误导致MyFaces无法创建<action-listener>org.primefaces.application.DialogActionListener</action-listener>，并且Don't do what I did. Don't create a
standard-faces-config.xmlfile. This prevents Faces from initializing properly. [The common project'sfaces-config.xmlfile wasn't being found, and renaming it seemed to fix the problem. Bad idea.] This mistake resulted in MyFaces failing to create<action-listener>org.primefaces.application.DialogActionListener</action-listener>, and this as well.
- 似乎确实需要将MyFaces StartupServletContextListener包含在web.xml中.
- 奇怪的未销毁Bean驱逐舰"错误似乎是由于切换到CDI而没有禁用MyFaces的Managed Bean支持.
- 由于我的
standard-faces-config.xml文件阻止正确的初始化，因此出现了多个启动问题.
- It seems that the MyFaces StartupServletContextListener was indeed necessary to include in web.xml.
- The strange "Bean Destroyer not published" error seemed to be due to switching to CDI but not disabling MyFaces' Managed Bean support.
- Multiple start-up issues due to my
standard-faces-config.xmlfile blocking proper initialization.
