Omnifaces cdi param与JSF 2.3之间的冲突

标签： jsf tomee omnifaces

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。我使用裸骨Webapp进行了测试并确认了这一点。

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，它只能运行一次。随后的试验给出：

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。

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，但要获取信息，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，并且插入了SAME jar。

答案 0 :(得分：1)

这不是OmniFaces，JSF和CDI中的错误。

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。

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。

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。

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

在upgrading测试服务器从TomEE 7.0.4到TomEE 8.0.0-M2之后，我自己在OmniFaces中偶然发现了此问题。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disable bean验证。

记录下来，这是完整的堆栈跟踪：
