我是CDI的新手.这是我的第一个例子,我正在尝试运行它.搜索过互联网后,我编写了以下代码:我想要注入的类
public class Temp {
public Temp(){
}
public String getMe(){
return "something";
}
}
Servlet的
@WebServlet(name = "NewServlet", urlPatterns = {"/NewServlet"})
public class NewServlet extends HttpServlet {
@Inject
public Temp temp;
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
out.println("<body>");
out.println("<h1> Here it is"+temp.getMe()+ "</h1>");
out.println("</body>");
}
}
...
但是我必须跟踪glassfish 4中的错误:
org.jboss.weld.exceptions.DeploymentException:WELD-001408在注入点[[BackedAnnotatedField] @Inject private xxx.example.NewServlet.temp]中带有限定符[@Default]的[Temp]类型的不满意依赖项
我究竟做错了什么？
