404在EJB上使用REST时未找到错误

我开发了一个消息传递EJB应用程序，其服务使用WILDFLY 9服务器。 现在应用程序正在运行，数据库已经完全正常运行，我正在尝试为这个应用程序开发一个RESTWeb服务。所以我创建了我的重启器：

package tn.carmate.webservice;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;


@ApplicationPath("rest")
public class RestActivator extends Application {

}

以及我的MessageResources.java，如下所示

package tn.carmate.webservice;

import java.util.List;

import javax.ejb.EJB;
import javax.enterprise.context.RequestScoped;
import javax.ws.rs.Consumes;
import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;

import tn.esprit.pi.Services.Services;
import tn.esprit.pi.persistance.Message;

@Path("message")
@RequestScoped
public class MessageRessource {

    @EJB
    Services servicemessage;

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("{idreceiver}")
    public Response getMessageList(@QueryParam(value = "idreceiver") int idReceiver) {

        List<Message> message = servicemessage.getMessageList(idReceiver);
        return Response.status(Status.OK).entity(message).build();

    }

    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Path("{idSrc/idDest/content}")
    public Response sendMessage(@QueryParam(value = "idSrc") int idSrc, @QueryParam(value = "idDest") int idDest,
            @QueryParam(value = "content") String content) {

        servicemessage.sendMessage(idSrc, idDest, content);
        return Response.status(Status.OK).build();
    }

    @DELETE
    @Path("{idm}")
    public Response deleteMessage(@QueryParam(value = "idm") int id) {
        servicemessage.deleteMessage(id);
        return Response.status(Status.OK).build();

    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("{idSender/idReceiver}")
    public Response getConversation(@QueryParam(value = "idSender") int idSender,
            @QueryParam(value = "idReceiver") int idReceiver) {
        List<Message> conversion = servicemessage.getConversation(idSender, idReceiver);
        return Response.status(Status.OK).entity(conversion).build();

    }


    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("{idR}")
    public Response returnInbox (@QueryParam(value = "idR")int idR){
        List<Message> listmessage = servicemessage.returnInbox(idR);
        return Response.status(Status.OK).entity(listmessage).build();
    }


    @DELETE
    @Path("{idc}")
    public Response deleteConversation(@QueryParam(value = "idc")int id){
        servicemessage.deleteConversation(id);
        return Response.status(Status.OK).build();
    }


}

仔细检查你的网址，我想应该是

http://localhost:8080

非

http://localhost:18080

。只是一个打字错误

其次，restful服务的应用程序基本路径设置为

rest

所以url应该是

http://localhost:8080/CarMate-web/rest/message？idreceiver=1

最后，

idreceiver

是一个查询参数，但@Path（“{idreceiver}”）将其视为路径参数

因此，在

http://localhost:8080/CarMate-web/rest/message？idreceiver=1

Rest端点期望在/message/{idreceiver}？idreceiver=1之后有一个路径变量，如注释中的

@Leonardo

所述

我建议以下列出的任何解决方案：

从方法中删除@Path

@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getMessageList(@QueryParam(value = "idreceiver") int idReceiver) {
List<Message> message = servicemessage.getMessageList(idReceiver);
return Response.status(Status.OK).entity(message).build();
}

并使用此URL:

http://localhost:8080/CarMate-web/rest/message/idreceiver？idreceiver=1

关于restful的路径，您是对的，但是端口是18080。请注意，我尝试使用执行，但仍然得到相同的404错误请注意，当我测试其余23:16:06143警告[org.jboss.resteasy.core.ExceptionHandler]（默认任务-34）无法执行：javax.ws.rs.NotFoundException:无法找到完整路径的资源：因为您有一个作为idreceiver的路径，我认为这应该是正确的调用：

http://localhost:8080/CarMate-web/rest/message/idreceiver？idreceiver=1

@GET
@Produces(MediaType.APPLICATION_JSON)
public Response getMessageList(@QueryParam(value = "idreceiver") int idReceiver) {
List<Message> message = servicemessage.getMessageList(idReceiver);
return Response.status(Status.OK).entity(message).build();
}

@GET
@Produces(MediaType.APPLICATION_JSON)
@Path("idreceiver")
public Response getMessageList(@QueryParam(value = "idreceiver") int idReceiver) {
List<Message> message = servicemessage.getMessageList(idReceiver);
return Response.status(Status.OK).entity(message).build();
}
