@PathVariable注解的使用

 一、映射路径变量得到的请求参数：

//  http://localhost:8081/api/v1.0/users/ming
@GetMapping("/{name}")
@PathVariable String name
{"createDate":"2021-08-12T15:36:03.801055+08:00","name":"ming"}



//  http://localhost:8081/api/v1.0/users/list/11
@GetMapping("list/{ids}")
@PathVariable long[] ids
[{"id":11}]

 二、例子：

@RequestMapping("/api/v1.0/users")
public class UserProfileController {
    private static CxLogger logger = CxLogManager.getLogger();

    @GetMapping("/{name}/{age}")
    public UserProfile hello(@PathVariable String name, @PathVariable Integer age) {
        UserProfile profile = new UserProfile();
        profile.setName(name);
        profile.setName(age);
        profile.setCreateDate(OffsetDateTime.now());
        return profile;
    }

    @GetMapping("list/{ids}")
    public UserProfile[] list(@PathVariable long[] ids) {
        if(ids != null ){
            UserProfile[] result = new UserProfile[ids.length];
            for (int i = 0; i < ids.length; i++) {
                UserProfile profile = new UserProfile();
                profile.setId(ids[i]);
                result[i] = profile;
            }
            return result;
        }
        return new UserProfile[0];
    }
  }
