Question

我正在Eclipse Mars和WildFly 8.2中进行一些CDI测试。

我有一个动态Web项目（作为EAR的模块）ItsProjectWEB托管一个简单的会话范围的bean

@SessionScoped
public class Cart implements Serializable {

    private static final long serialVersionUID = 1L;

    public Cart() {}

    List<String> list = new ArrayList<>();

    public List<String> addAndGet(String item){
        list.add(item);
        return list;
    }

}

以及注入和调用bean的servlet

@WebServlet("/ItsServlet")
public class ItsServlet extends HttpServlet {

    @Inject Cart cart;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        StringBuilder text=new StringBuilder();
        text.append("Cart = "+cart.addAndGet("Item #"+LocalTime.now().getSecond()));
        text.append("\nServed at: "+request.getContextPath());

        response.getWriter().append(text);
    }

    //irrelevant code
}

一切正常，这是项目的结构：

我的想法是创建一个单独的动态Web项目，放置CDI bean，将此项目添加到我的EAR，并能够从其他模块中引用它。这就是我所做的：

通过复制第一个

ItsProjectCDI

将此项目添加到ItsProjectWEB的Java构建路径（右键单击 - ＆gt; Java构建路径 - ＆gt;项目 - ＆gt;添加...）
尝试通过@Inject ItsCart cart;

但是我在服务器日志中得到了这个错误

我无法理解这里发生的事情，新项目与旧项目相同，但注射不会成功。我做错了什么？

将CDI项目作为库添加到Eclipse中的EAR
