Question

我在wildfly中部署应用程序时遇到问题，该应用程序包含使用@Inject注入DAO的RESTful服务。

尝试在wildfly中部署应用程序时，这是日志中的错误消息：

Deploying /home/john/codebase/servers/wildfly-8.2.0.Final/standalone/deployments/HouseCompetitionDashboard-1.0-SNAPSHOT.war
{"JBAS014671: Failed services" => {"jboss.deployment.unit.\"HouseCompetitionDashboard-1.0-SNAPSHOT.war\".WeldStartService" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"HouseCompetitionDashboard-1.0-SNAPSHOT.war\".WeldStartService: Failed to start service
Caused by: org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type DAO with qualifiers @Default
  at injection point [BackedAnnotatedField] @Inject private org.jmcdonnell.dashboard.services.PlayerService.dao
  at org.jmcdonnell.dashboard.services.PlayerService.dao(PlayerService.java:0)
"}}

这些课程如下：

@Named
public class DAO {
}



@Stateless
@Path("player")
public class PlayerService {

    @Inject
    private DAO dao;

    @POST
    @Consumes({"application/xml", "application/json"})
    public void create(Player entity) {
        //dao.create(entity);
    }
}

稍后DAO类将包含一个实体管理器，但目前它并不像我至少希望注入工作。有人有什么想法吗？

@Named annotaion期望某些名称和名称未设置 - 它会生成默认名称，但是，name会生成与bean的驼峰案例名称相同的名称。您需要尝试指定名称或使用驼峰案例作为bean名称。

Java EE RESTful服务字段注入
