Spring Boot Thymeleaf fill path variable from controller -


on page projects have button navigate collection of clusters belong project.

project , cluster have own controllers.

on projects page have following button:

            <td><a th:href="@{/projects/project/{pid}/clusters(pid=${p.id})}" class="btn btn-info" role="button">clusters</a> </td>

this brings me url /projects/project/{pid}/clusters, pid id of project. pid filled in here. on clusters page have button create new cluster. code button:

<a th:href="@{'/projects/project/{pid}/clusters/create'}" class="btn btn-info" role="button">create cluster</a>

when click button following url: /projects/project/%7bpid%7d/clusters/create.

so problem doesn't have pid(id of project) how can pass project id it?

@controller @requestmapping("/projects/project/{pid}/clusters") public class clustercontroller {      @requestmapping(value="/create", method = requestmethod.get)     public string createcluster(model model){         cluster cluster = new cluster();         model.addattribute("cluster", cluster);         return "createcluster";     }      @requestmapping(value = "/create", method = requestmethod.post)     public string createtestcluster(@pathvariable("pid") integer projectid, @modelattribute("cluster") testcluster cluster){         system.out.println(projectid);         project project = this.projectservice.findprojectbyid(projectid);         cluster.setproject(project);         this.clusterservice.cluster(cluster);         return "redirect:/clusters";     }

i'm new spring boot don't know how fix this.
