使用jaxrs在rest-service中找不到参数的注入源

我有问题,我的休息服务的两个方法带来了部署错误,没有注入源.

我的服务看起来像这样:

@Path("/chatservice")
public class ChatServiceImpl implements ChatService{

@POST
@Path("/registerToServer")
@Consumes(MediaType.APPLICATION_JSON)
@Override
public Response registerToServer(User user) {

    UserList userListObject = getAllChatableUsers(user);

    return Response.status(200).entity(userListObject).build();
}

@POST
@Path("/sendMessage")
@Consumes(MediaType.APPLICATION_JSON)
@Override
public Response sendMessage(Message message) {
    boolean isSuccess = putMessageIntoDatabase(message);

    return Response.status(200).build();
}

@POST
@Path("/getAllMessagesForUser")
@Consumes(MediaType.APPLICATION_JSON)
@Override
public Response getAllMessagesForUser(UserWithRecipient userWithRecipient) {

    return Response.status(200).build();
}

@POST
@Path("/getAllMessagesForUser/{numberOfMessages}")
@Consumes(MediaType.APPLICATION_JSON)
@Override
public Response getMessagesForUser(@PathParam("numberOfMessages") int numberOfMessages, UserWithRecipient userWithRecipient) {

    return Response.status(200).build();
}

问题的类如下:

@XmlSeeAlso(User.class)
@XmlRootElement
public class UserWithRecipient {

private User user;
private User recipient;

public UserWithRecipient() {
}

public User getUser() {
    return user;
}

public void setUser(User user) {
    this.user = user;
}

public User getRecipient() {
    return recipient;
}

public void setRecipient(User recipient) {
    this.recipient = recipient;
}
}

我得到的错误如下:

 [[FATAL] No injection source found for a parameter of type public javax.ws.rs.core.Response de.hszg.fei.ws.service.ChatServiceImpl.getMessagesForUser(int,de.hszg.fei.ws.model.UserWithRecipient) at index 0.; source='ResourceMethod{httpMethod=POST, cOnsumedTypes=[application/json], producedTypes=[], suspended=false, suspendTimeout=0, suspendTimeoutUnit=MILLISECONDS, invocable=Invocable{handler=ClassBasedMethodHandler{handlerClass=class de.hszg.fei.ws.service.ChatServiceImpl, handlerCOnstructors=[org.glassfish.jersey.server.model.HandlerConstructor@6da34189]}, definitiOnMethod=public javax.ws.rs.core.Response de.hszg.fei.ws.service.ChatServiceImpl.getMessagesForUser(int,de.hszg.fei.ws.model.UserWithRecipient), parameters=[Parameter [type=int, source=numberOfMessages, defaultValue=null], Parameter [type=class de.hszg.fei.ws.model.UserWithRecipient, source=null, defaultValue=null]], respOnseType=class javax.ws.rs.core.Response}, nameBindings=[]}']]]

你能告诉我这堂课有什么问题吗？我也不明白,为什么这个sendMessage()方法不会带来同样的问题.

我发现问题是,我导入了错误的@PathParamAnnotation.
