无法制作焊缝扫描豆

Question

我一定是漏掉了什么，但我无法让 Weld 正常工作！这是一个简单的 webapp，一个 servlet，一个服务（我想注入 servlet）

这是文件：

pom.xml

    <dependency>
        <groupId>org.jboss.weld.servlet</groupId>
        <artifactId>weld-servlet-core</artifactId>
        <version>2.3.4.Final</version>
    </dependency>

context.xml

<Context>
       <Resource name="BeanManager"
          auth="Container"
          type="javax.enterprise.inject.spi.BeanManager"
          factory="org.jboss.weld.resources.ManagerObjectFactory"/>
    </Context>

我的服务

import javax.enterprise.context.SessionScoped;
import javax.inject.Inject;
import javax.inject.Named;

@Named
@SessionScoped
public class ServiceTest {


    public String test(){
        return "hello world";
    }


}

我的小服务程序：

public class Hello extends HttpServlet {

    @Inject
    private ServiceTest service;

    @Override
       public void doGet(HttpServletRequest request, HttpServletResponse response)
                   throws IOException, ServletException {
          // Set the response message's MIME type.
          response.setContentType("text/html;charset=UTF-8");
          // Allocate a output writer to write the response message into the network socket.
          PrintWriter out = response.getWriter();

             try {
             out.println("<!DOCTYPE html>");  // HTML 5
             out.println("<html><head>");
             out.println("<meta http-equiv='Content-Type' content='text/html; charset=UTF-8'>");
             String title = service.test();
             out.println("<title>" + title + "</title></head>");
             out.println("<body>");
             out.println("<h1>" + title + "</h1>");  // Prints "Hello, world!"
             out.println("</body></html>");
          } finally {
             out.close();  // Always close the output writer
          }
       }
}

我只是得到一个 NPE ... 没有别的。

这是我的 Tomcat 7

beans.xml（在 META-INF 下）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee">

    </scan>

这意味着 Weld 在您的 WAR 中没有找到任何 bean 存档。请注意，在 WAR 中，beans.xml 必须命名为 WEB-INF/beans.xml 或 WEB-INF/classes/META-INF/beans.xml（另请参阅规范 12.1. Bean archives）。我猜你有 META-INF/beans.xml.
