使用＆＃34; @ QueryParam＆＃34; cxf restful service返回404错误

Question

我想使用url中的restful查询参数从服务器查询信息。 java代码使用@QueryParam检索查询参数。

我的请求网址是这样的：

GET
http://localhost:8080/ApacheCXF-XML-JSON-IO/services/playerservice/query?id=238
Content-Type:application/x-www-form-urlencoded
accept:application/json

界面是：

@Path("/playerservice")
public interface IPlayerService {
    // http://localhost:8080/ApacheCXF-XML-JSON-IO/services/playerservice/getplayer/238
    @GET
    @Path("getplayer/{id}")
    @Consumes({MediaType.APPLICATION_FORM_URLENCODED})
    @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public PlayerType getPlayerInfo(@PathParam("id") int playerId);

    // http://localhost:8080/ApacheCXF-XML-JSON-IO/services/playerservice/query?id=238
    @GET
    @Path("query")
    @Consumes({MediaType.APPLICATION_FORM_URLENCODED})
    @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public PlayerType queryPlayerInfo(@QueryParam("id") int id);
}

接口的实现是：

@Service("playerService")
public class PlayerServiceImpl implements IPlayerService {
    /**
     * retrieves a player object based on the playerId supplied in the formal argument using @PathParam
     */
    @Override
    public PlayerType getPlayerInfo(int playerId) {

        // retrieve player based on the id supplied in the formal argument
        PlayerType getplayer = new PlayerType   ();
        getplayer.setPlayerId(playerId);
        getplayer.setName("Allan Donald");
        getplayer.setAge(47);
        getplayer.setMatches(72);
        return getplayer;
    }

    @Override
    public PlayerType queryPlayerInfo(int playerId) {
        // retrieve player based on the id supplied in the formal argument
        PlayerType getplayer = new PlayerType   ();
        getplayer.setPlayerId(playerId);
        getplayer.setName("Allan Donald");
        getplayer.setAge(47);
        getplayer.setMatches(72);
        return getplayer;
    }
}

启动tomcat后，我使用postman来测试restful服务。我发送如上所述的get请求，但服务器返回http 404错误，如下所示：
