WELLD-001408类型[LdapService]在注入点具有限定符[@named]的不满足依赖项

Question

我的LdapService类是一个无状态EJB，默认无参数构造函数（此项目是一个EJB包）

@Stateless
public class LdapService {

@Inject
public LdapService() {

} ...

我试着把它注入到另一个类中，比如：

public class UserService {

private static final Logger logger = LoggerFactory.getLogger(UserService.class.getCanonicalName());
@Inject
private LdapService registerService;

@EJB(beanName = "Janus-session-1.0.jar#UserBean")
private TUserBean userBean;

...}

CDI可以识别带有@EJB注释的bean,但注入点向我抛出了关于@Inject的错误：

如果在LdapService中使用@named（“LdapService”）,然后在注入点使用：

@Inject @Named("LdapService") private LdapService registerService;

然后我得到了这个错误：

部署失败。消息是：org.jboss.weld.exceptions.deploymentexception：WELD-001408类型[LdapService]在注入点[[field]@inject@named net.ab4cus.project.business.userservice.registerservice]未满足限定符[@named]的依赖项

我如何解决这个错误并消除歧义？或者对其他bean做@inject的正确方法是什么？

谢谢你。

如果我尝试使用前端，任何时候访问一个bean时，我都会得到这个错误（对于每个bean）：

SEVERE: 
java.lang.IllegalArgumentException: Can not set net.ab4cus.project.session.TUserBean field net.ab4cus.project.business.UserService.userBean to net.ab4cus.project.session.UserBean_o7pydo_NoIntfViewImpl

我正试图解决这个问题，但现在没有任何线索：/

Answer 1

我的第一个错误的解决方法是：

-从LdapService和默认构造函数中删除@stateless和@inject

public class LdapService {

}...

-为LdapService创建接口并@将此接口注入UserService

public class UserService {

private static final Logger logger = LoggerFactory.getLogger(UserService.class.getCanonicalName());
@Inject
private LdapServiceInterface registerService;

@EJB(beanName = "Janus-session-1.0.jar#UserBean")
private TUserBean userBean;

...}
