Spring Hateoas没有为以下请求映射创建适当的链接:
@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());
}
调用/ member / 12345时将返回:
{
member: {
//omitted for brevity
},
_links:[
{
href: .../members/12345
},
{
href: ../teams?memberId = 12345
}
]
}
但是它返回:
{
member: {
//omitted for brevity
},
_links:[
{
href: .../members/12345
},
{
href: ../teams/12345
}
]
}
为什么是这样?即使我使用@RequestParam,它也完全忽略了过滤器。任何建议在此问题上表示赞赏。

免责声明:从未使用过Spring HATEOAS。
但乍看之下,您似乎混淆了两种URL参数类型:@PathVariable
用于路径变量,例如.../teams/TEAM_ID
@RequestParam
用于查询参数,例如.../teams?id=TEAM_ID
