我在用
和其他Java EE工件。
如下所示的
@FacesValidator中的注入(inject)点，@FacesValidator(value="testValidator")
public class TestValidator implements Validator {
@Inject
private DemoEJB ejb;
@Inject
private ManagedBean managedBean;
@Override
public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
// Use the injected EJB and/or managed bean here.
}
}
这些注入(inject)点仍然是
null(我没有明确尝试注入(inject)EJB，但它不应该像托管bean那样发生)。由于上面提到的Mojarra版本仍然可以作为快照使用，因此我尝试使用与OmniFaces相同的2.0版本将其降级到2.2.10(或者在Mojarra 2.2.10和2.3上也对OmniFaces 2.1-SNAPSHOT进行了尝试。也可以选择0-m01)，但无济于事。
当我将Majarra降级为2.2.8-02(或者与OmniFaces 1.8.1、2.0和2.1-SNAPSHOT尝试)时，此方法起作用。我没有尝试其他Mojarra版本。
是否已通过OmniFaces(不需要任何其他依赖项和/或配置)的方式删除了对使用EJB和CDI注入(inject)点的
@FacesValidator和@FacesConverter候选对象的支持(对于较新的Mojarra版本)？我还没有在
@FacesConverter中明确尝试过，只是因为使用有问题的NetBeans IDE改变了这么多库，或者改变了很多次，从本质上来说，它在Windows上也非常慢，整个过程从黎明到黄昏。编辑 :

最佳答案
这是由于Mojarra 2.2.9中的更改引起的。在2.2.8中可以正常工作。我在GlassFish 4.1和WildFly 8.2中都复制了它。在扫描了2.2.9 release notes和相关的变更包中列出的所有问题之后，这似乎是issue 3552反向移植到JSF 2.2.x的结果。他们在内部禁止检查组件，行为，验证器和转换器的可注入(inject)性，这些组件隐式地将它们注册为CDI管理的bean候选者。换句话说，在2.2.x到2.2.9期间，Mojarra在提到的工件中无意中提供了“本地” @Inject支持。
为了能够通过OmniFaces注入(inject)@FacesConverter和@FacesValidator以便正常运行，您需要添加一个空的/WEB-INF/beans.xml或至少一个将bean-discovery-mode设置为all而不是annotated的代码。
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:weld="http://jboss.org/schema/weld/beans"
bean-discovery-mode="all"
>
<!-- ... -->
</beans>
它已经是默认值，您也可以省略
bean-discovery-mode属性。技术上的区别在于，
bean-discovery-mode="all"将所有合格类注册作为CDI管理的bean，而bean-discovery-mode="annotated"仅将具有显式CDI作用域注释的类注册(例如@RequestScoped)作为CDI管理的bean，因此@FacesConverter和@FacesValidator失败。
