我試圖將RESTEasy與AppEngine上的Weld結合起來，但有麻煩做構造函數注入。CDI/Weld無法做RESTEasy資源的構造函數注入
我已經添加了RESTEasy CdiInjectorFactory上下文參數和Weld servlet偵聽器。
我的RESTEasy應用程序類的樣子：
public class MyApplication extends Application {
@Override
public Set<Class<?>> getClasses() {
HashSet<Class<?>> classes = new HashSet<Class<?>>();
classes.add(CustomerResource.class);
return classes;
}
}
和CustomerResource：
@Path("/rest/app/customers")
public class CustomerResource {
private final CustomerService customerService;
@Inject
public CustomerResource(CustomerService customerService) {
this.customerService = customerService;
}
..
}
向客服就像是一個簡單的服務：
public class CustomerService {
public List<Customer> getCustomers() {
..
}
}
當我啓動服務器我在日誌中看到：

從此日誌記錄中，我可以看到我的RESTEasy應用程序和資源類被發現。請注意，我沒有看到有關CustomerService的提及。
當我訪問我的資源在瀏覽器中，我得到：

是的RESTEasy試圖創建一個新的CustomerResource實例，而不是從焊縫採摘呢？
我也嘗試過使用字段注入（而不是構造函數注入），然後我可以看到CustomerService很好地注入到CustomerResource中。
我只喜歡構造函數注入，並想知道在使用Weld時RESTEasy資源類是否支持這種方法？
