Omnifaces cdi param与JSF 2.3之间的冲突 [英] Conflict between Omnifaces cdi param and JSF 2.3

问题描述

在将服务器从tomee plume 7升级到tomee plume 8之后，我的Web应用程序遇到了Omnifaces cdi param问题.我使用裸露的Web应用程序进行了测试并确认了这一点.

My web app encountered a problem with Omnifaces cdi param after upgrading the server from tomee plume 7 to tomee plume 8. I tested with a bare bone webapp and confirmed this.

我的豆子:

@javax.faces.view.ViewScoped
@javax.inject.Named
public class Bean2 implements java.io.Serializable {
  @javax.inject.Inject @org.omnifaces.cdi.Param
  private String tag;
  private String tag2;

  @javax.annotation.PostConstruct
  public void init() {
    if (getTag() == null || getTag().length()==0) {
        setTag2("None injected");
    }
    else 
        setTag2(getTag() + " injected");
    // Getters and setters

}

我的JSF视图:

<h:body>
    Tag: <h:outputText value="#{bean2.tag}" />
    <br/>
    <p:inputText readonly="true" value="#{bean2.tag2}"/>
</h:body>

我尝试了 http://localhost:8080/test/inject2.jsf?tag = ABC ，并且只能运行一次.随后的试验给出:

I tried http://localhost:8080/test/inject2.jsf?tag=ABC and it works once only. Subsequent trials give:

java.lang.IllegalArgumentException: Unknown property tag of class com.mycompany.Bean2
at org.apache.bval.jsr.job.ValidateProperty$FindDescriptor.handleProperty(ValidateProperty.java:216)
at org.apache.bval.jsr.job.ValidateProperty$WalkGraph.handleProperty(ValidateProperty.java:312)
Caused by: javax.el.ELException: Error reading [tag] on type [com.mycompany.Bean2$$OwbNormalScopeProxy0]
at javax.el.BeanELResolver.getValue(BeanELResolver.java:98)
at com.sun.faces.el.DemuxCompositeELResolver._getValue(DemuxCompositeELR...

如果我重新启动服务器，它也只能运行一次.

If I restart the server, it also works once only.

我的环境Java:openjdk版本"1.8.0_191"，Primefaces 6.1，Omnifaces 2.6.9.我知道没有多少人使用TomEE，但有关信息，TomEE羽7基于Tomcat 8，Mojarra JSF 2.2，而TomEE羽8基于Tomcat 9，Mojarra JSF 2.3.当然还有更多的区别，但是测试Web应用程序是如此简单，以至于影响我的应该仅是Tomcat和JSF版本，并插入了SAME jar.

My environment Java: openjdk version "1.8.0_191", Primefaces 6.1, Omnifaces 2.6.9. I know not many people use TomEE but for info, TomEE plume 7 is based on Tomcat 8, Mojarra JSF 2.2 whereas TomEE plume 8 is based on Tomcat 9, Mojarra JSF 2.3. There are of course more differences but the test web app is so simple that what affects me should be Tomcat and JSF version only, with the SAME jar dropped in.

推荐答案

这不是OmniFaces，JSF和CDI中的错误.

This is not a bug in OmniFaces nor JSF nor CDI.

这是BVal(Apache的Bean验证实现(JSR303))中的错误.堆栈跟踪至少可以确认这一点.它从BVal类中引发了异常.

This is a bug in BVal (Apache's implementation of Bean Validation (JSR303)). The stack trace at least confirms that. It threw the exception from within the BVal classes.

OmniFaces CDI @Param批注具有在注入值之前自动执行Bean验证的功能.在较旧的BVal版本和其他BV实现(例如Hibernate Validator)中，这种方法始终可以正常工作.

The OmniFaces CDI @Param annotation has the feature that it automatically performs Bean Validation before injecting the value. This has always worked fine with older BVal versions and other BV implementations (e.g. Hibernate Validator).

您最好的选择是将此问题报告给BVal伙计们.同时，您可以通过在@Param上禁用BV来解决此问题.

Your best bet is to report this issue to BVal guys. In the mean while, you can work around this problem by disabling BV on the @Param.

@Inject @Param(disableBeanValidation=true)
private String tag;

在从TomEE升级测试服务器之后，我在OmniFaces中偶然发现了这个问题7.0.4至TomEE 8.0.0-M2.与您所观察到的完全相同的问题是在IT期间发生的.解决方法是禁用 bean验证.

I stumbled upon this issue myself in OmniFaces after upgrading the test server from TomEE 7.0.4 to TomEE 8.0.0-M2. Exactly the same problem as you've observed occurred during an IT. The fix was to disable the bean validation.

为记录起见，这是完整的堆栈跟踪:
