JBoss EAP 7，仅允许焊接异常 @Dependent
JBoss EAP 7, Weld Exception Only @Dependent is allowed
在尝试将应用程序从 JBoss EAP 5 迁移到 JBoss EAP 以及添加一些额外功能（例如 JAX-RS）时，我收到以下错误：
WELD-000082：class net.MyCompany.My.service.MyIPAuthJaxRsService 的无状态会话 bean 不允许作用域接口 javax.enterprise.context.RequestScoped。只允许@Dependent。

两个 JAX-RS 类 是：

网上搜了一下，发现下面这篇文章提供了线索：

我也偶然发现了这个：
http://docs.jboss.org/resteasy/docs/2.0.0.GA/userguide/html/CDI.html
似乎发生在 EJB 中 -Jar.xml 我声明 EJB 是无状态会话 bean 并且不在 java 类 本身中注释它们CDI/Weld 将它们默认为 @Dependent，例如来自 JBoss 文章 A CDI bean that does not explicitly define a scope is @Dependent scoped by default.
只需将以下导入和注释添加到 类:
package net.mycompany.my.service;
import javax.ejb.Stateless;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;

基本上检查您是否使用 @Stateless 注释了 EJB，并添加了正确的导入 import javax.ejb.Stateless;
Edit - 正如@SteveC 指出的那样，我已经删除了覆盖但是当我按照他的建议尝试从 MyIPAuthJaxRsServiceApplication 中删除@Stateless 时，我最终再次获得异常MyIPAuthJaxRsServiceApplication。另外值得注意的是，这个例子甚至没有工作，因此 EJB 在 EJB-Jar.xml 中并且注释可能甚至没有必要，我试图在 EAR 中使用 EJB 项目和 jar，注释EJB 与 JAX-RS 但显然它不受支持，因为我在这里与 JBoss 的人一起工作
https://developer.jboss.org/message/972433#972433
看起来您必须有一个用于 JAX-RS 的 servlet 容器，而 EJB 可以有 web 服务注释的事实并不意味着它们正在使用 servlet 容器 - 好吧，我试过了！此外，此问答更多是为了修复 A CDI bean that does not explicitly define a scope is @Dependent scoped by default.，我为此苦苦挣扎了一段时间，并认为如果其他人 运行 遇到同样的问题，我会帮助他们。
