我只能将CDI bean注入托管类中。 Struts创建了自己的实例，因此Struts Bean没有容器管理。

I only can inject your CDI beans in managed classes. Struts creates its own instances, so Struts beans are no container managed.

我不知道Struts是否具有能够注入CDI bean的插件，但是您可以查找

I don't know if Struts has a plugin able to inject CDI beans, but you can lookup the Bean Manager in JNDI tree.

public BeanManager getBeanManager() {
    try {
        Context jndiContext = new InitialContext();
        return (BeanManager) jndiContext.lookup("java:comp/BeanManager");
    } catch (NamingException e) {
        // handle the exception
    }
}

在您的应用程序中，可以使用以下命令：

In your application you can use this:

BeanManager manager = BeanManagerUtil.getBeanManager();
manager.getBeans(MyClass.class); 

对于getBeans方法返回的每个bean，您都需要获取bean引用

For each bean returned by getBeans method you need to get the bean reference

CreationalContext ctx = manager.createCreationalContext(bean);
MyClass myClass = manager.getReference(bean, MyClass.class, ctx);
