Spring Hateoas 忽略查询参数

Question

Spring Hateoas 没有为以下请求映射创建适当的 link：

@GetMapping("/member/{id}")
public MemberResource getMemberById(@RequestParam String id){
     Member member = MemberService.getMemberById(id);
     return new MemberResource(member);
}


public class MemberResource extends ResourceSupport{

     public MemberResource(Member member){
  add(linkTo(methodOn(MemberController.class).getMember(member.getId)).withSelfRel());
        add(linkTo(methodOn(TeamsController.class).getTeams(memberId)).withRel("teams"));
        }}


        @GetMapping("/teams")
        public List<TeamResource> getTeamsById(@RequestParam String id)          {
            List<Team> teams = teamService.getTeamsById(id);
            return teams.stream().map(TeamResource::new).collect(Collectors.toList());
        }

当调用 /member/12345 时期望 return:

{
     member: {
       //omitted for brevity
     },
    _links:[
       {
         href: .../members/12345
       },
       {

         href: ../teams?memberId = 12345

       }

      ]
}

而是 returns:

{
     member: {
       //omitted for brevity
     },
    _links:[
       {
         href: .../members/12345
       },
       {

         href: ../teams/12345

       }

      ]
}

这是为什么？即使我使用@RequestParam，它也完全忽略了过滤器。在此问题上，我们将不胜感激。

免责声明：从未使用过 Spring HATEOAS。

但乍一看，您似乎混淆了两种 URL-参数类型：

• @PathVariable 对于像 .../teams/TEAM_ID
这样的路径变量
• @RequestParam 查询参数如 .../teams?id=TEAM_ID
