@FacesValidator和@FacesConverter中的EJB和CDI注入点在较新版本的JSF中无法通过OmniFaces工作

我在用，

  • Mojarra 2.3.0-m01
  • OmniFaces 2.0。
  • PrimeFaces 5.1 final
  • PrimeFaces Extension 3.0.0
  • GlassFish Server 4.1

以及其他Java EE工件。

@FacesValidator中的注入点，如下所示，

@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.
    }
}

这些注入点仍然是null（我没有明确地尝试注入EJB，但它不应该像托管bean那样发生）。

由于上面提到的Mojarra版本仍可作为快照使用，我尝试将其降级为2.2.10，使用相同版本的OmniFaces 2.0（或者也尝试使用OmniFaces 2.1-SNAPSHOT - 在Mojarra 2.2.10上）和2.3.0-m01交替）但无济于事。

当我将Majarra降级到2.2.8-02（用OmniFaces 1.8.1,2.0和2.1-SNAPSHOT替代）时，这很有效。我没有尝试其他Mojarra版本。

是否支持通过OmniFaces（而不需要任何附加依赖关系和/或配置）删除新版本的EJB和CDI注入点的@FacesValidator和@FacesConverter候选者钻嘴鱼科

我还没有在@FacesConverter中明确尝试过，因为使用一个错误的NetBeans IDE来改变这么多的库，这个版本在Windows上也非常慢，从黎明到黄昏整整一天

这是由Mojarra 2.2.9的变化引起的。它在2.2.8中工作正常。我在GlassFish 4.1和WildFly 8.2中重现了它。在扫描2.2.9 release notes中列出的所有问题以及相关的更改包之后，它似乎是issue 3552向JSF 2.2.x后退的结果。他们在内部禁用了检查组件，行为，验证器和转换器的可注入性，这些组件，行为，验证器和转换器隐式将它们注换句话说，在2.2.x至2.2.9期间，Mojarra无意中提供了＃34; native＆＃34; @Inject支持上述文物。

为了让@FacesConverter和@FacesValidator中的注入无论如何都能通过OmniFaces工作，您需要添加一个空的/WEB-INF/beans.xml或至少一个bean-discovery-mode设置为{ {1}}代替all。

annotated

它已经是默认值，您也可以省略<?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> 属性。

技术上的区别在于bean-discovery-mode会将所有符合条件的类注册为CDI托管bean，而bean-discovery-mode="all"仅注册具有显式CDI范围注释的类，例如{{1}作为CDI托管bean，因此bean-discovery-mode="annotated"和@RequestScoped会失败。
