谁可以修复有关球衣hk2 SystemInjecteeImpl的MultiException

时间：2019-01-27 16:03:51

标签： rest jersey cdi hk2

我有一个Tomcat 8.5的J2EE应用程序。现在，我尝试在基于球衣2.26-b03的休息服务中使用CDI。但是，当我尝试在类SimpleRestService的其余服务deviceController.getDevices().get("2").getCurrentvalue()中调用方法allDevices()时，会收到MultiException：

在该异常之后，我另外创建了类JerseyResourceConfiguration并将我要注入的bean（DeviceController）绑定到其余服务（SimpleRestService）。但这并不能解决问题。下一步，我尝试通过SimpleRestService-Constructor注入它。

那也没有帮助。我还尝试了hk2的依赖关系（请参阅pom.xml-目前hk2依赖关系已被注释掉）。

简单的休息服务

@Path("simple")
@RequestScoped
public class SimpleRestfulService {

    @Inject
    private DeviceController deviceController;


    //private final DeviceController deviceController;

    //@Inject
    //public SimpleRestResource(DeviceController deviceController){ 
    //      this.deviceController = deviceController;
    //}



    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("devices")
    public Response allDevices() 
    {
      System.out.println("DeviceController: " + this.
          deviceController.getDevices().get("2").getCurrentvalue());

          return Response
                  .status(200)
                  .header("Access-Control-Allow-Origin", "*")
                  .entity("{\"success\":\"Message received\"}")
                  .build();
    }
}

DeviceController（要注入的Bean）

@Named
@SessionScoped
public class DeviceController implements Serializable {

      //methods like getDevices()

}

ApplicationCinfiguration类

@ApplicationPath("/api/v1")
public class RESTApplicationConfiguration extends Application {
}

JerseyConfiguration类

public class JerseyResourceConfiguration extends ResourceConfig {

     public JerseyResourceConfiguration() {
            packages("path.to.restservice");   //SimpleRestSrevice
            register(new AbstractBinder() {

                  @Override
                  protected void configure() {
                      bind(new 
                           DeviceController()).to(DeviceController.class);
                  }
              });
     }
}

更新1

我从ApplicationConfiguration类中删除了@ApplicationPath 

public class RESTApplicationConfiguration extends Application {
}

到JerseyConfiguration类

@ApplicationPath("/api/v1")
public class JerseyResourceConfiguration extends ResourceConfig {

     public JerseyResourceConfiguration() {
            packages("path.to.restservice");   //SimpleRestSrevice
            register(new AbstractBinder() {

                  @Override
                  protected void configure() {
                      bind(new 
                           DeviceController()).to(DeviceController.class);
                  }
              });
     }
}

简单的休息服务

@Path("simple")
@RequestScoped
public class SimpleRestfulService {

    @Inject
    private DeviceController deviceController;

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("devices")
    public Response allDevices() 
    {
      System.out.println("DeviceController: " + this.
          deviceController.getDevices().size());

          return Response
                  .status(200)
                  .header("Access-Control-Allow-Origin", "*")
                  .entity("{\"success\":\"Message received\"}")
                  .build();
    }
}

但是现在在SimpleRestfulService中，我没有得到bean DeviceController的当前状态。在方法allDevices（）中，我尝试从DeviceController打印getDevices（）的大小。但是我总是得到零。但是在bean本身中它会打印出例如20.

我希望DeviceController bean可以成功地注入到其余服务SimpleRestService中，从而调用设备列表。我还尝试了其他与hk2相关性不同的解决方案，但结果始终相同。

有人能看到什么问题吗？
