Java org.jboss.weld.exceptions.DeploymentException:weld-001408类型的未满足依赖项

我有一个依赖项为的

LoginCrudService

   @Inject
    public LoginCrudService(@Nonnull @LoginService final EntityManager entityManager) {
        super(entityManager);
    }

其中

@LoginService

正确地指向了正确的接口

@Qualifier
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.CONSTRUCTOR, ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER, ElementType.TYPE})
public @interface LoginService {
}

当我将其部署到JBossAS 7.1上时，我看到

org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [EntityManager] with qualifiers [@LoginService] at injection point [[parameter 1] of [constructor] @Inject public com.myorg.bb.persistence.LoginCrudService(EntityManager)]

这个错误意味着什么？如何修复它？

我怀疑您的应用程序缺少库

---

通过检查JBoss_HOME/standalone/log/server.log中的JBoss服务器日志，可以发现异常情况。log

您是否为合格的EM部署了工作生产者？您所说的工作生产者是什么意思？我是指返回

EntityManager

的公共方法，用

@products

和

@LoginService

注释<错误中提到的代码>参数1是

@LoginService

限定符，因此生产方似乎有问题。
