使用omnifaces时焊接类加载异常

时间：2014-02-28 12:45:50

标签： java jetty omnifaces weld

在我决定从tomee web profiler迁移到jetty（9.0.7）之前，我一直在我的jsf 2.2应用程序中使用omnifaces而没有问题。它似乎有一些注释和CDI相关的问题阻止Weld（2.1.2.Final）和Omnifaces（1.7）很好地适应，我使用Omnifaces的唯一功能是隐藏我的URL的扩展名。

项目设置的简要视图：

相关的POM依赖项：

        <!--OmniFaces-->
    <dependency>
        <groupId>org.omnifaces</groupId>
        <artifactId>omnifaces</artifactId>
        <version>1.7</version>
    </dependency>
 <!--Weld for cdi in jetty--> 
    <dependency>
        <groupId>org.jboss.weld.servlet</groupId>
        <artifactId>weld-servlet</artifactId>
        <version>${weld.version}</version>
        <scope>runtime</scope>
    </dependency>
web.xml中的

：

    <context-param>
    <param-name>org.omnifaces.FACES_VIEWS_SCAN_PATHS</param-name>
    <param-value>/*.xhtml</param-value>
</context-param>

所有焊接相关的内容都来自override-web.xml（在web.xml之后解析）：

    <!--WELD-->
<listener>
    <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
</listener>
<resource-env-ref>
    <resource-env-ref-name>BeanManager</resource-env-ref-name>
    <resource-env-ref-type>
        javax.enterprise.inject.spi.BeanManager
    </resource-env-ref-type>
</resource-env-ref>
   <!--weld complains if the following is not done manually :-S-->
<listener>
    <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>

我试图保持我的应用程序不受不必要的xml配置的限制，直到现在我还设法这样做了。如果我通过在beans.xml中添加以下内容来指示焊接排除Omnifaces中有问题的类：< / p> 

     <scan>
     <exclude name="org.omnifaces" />
     <exclude name="org.omnifaces.cdi.param.RequestParameterProducer"/>
      <exclude name="org.omnifaces.validator.JsfLabelMessageInterpolator"/>
      <exclude name="org.omnifaces.util.Platform"/>
 </scan>

然后一切运行正常，omnifaces做它的工作，并从网址中删除扩展，焊接不会抱怨什么，所以我的问题是这是否是现在唯一的方法，或者是有没有更好的方法来解决这个问题，而不会污染我的beans.xml？

下面是我在使用mtn jetty时遇到的异常的副本：运行：

Caused by: java.lang.ClassNotFoundException: javax.validation.ConstraintViolation
Caused by: java.lang.ClassNotFoundException: javax.validation.MessageInterpolator
Caused by: java.lang.ClassNotFoundException: javax.validation.ValidatorFactory

这些问题是由于运行时类路径中缺少JSR303 Bean Validation API而引起的，而OmniFaces CDI bean期望它存在。这确实是OmniFaces依赖文档中的一个不明确之处。这将被解决。

除了明确地将这些类作为正确的CDI托管bean进行扫描之外，您还可以考虑实际安装JSR303 API，并在必要时安装JSR303实现以及Jetty中的CDI API / impl。 how to install CDI in Tomcat上的答案也适用于您的Jetty案例。
