我试图理解cmd curl和HttpClient(java.net.http.*)类如何在Java中一起工作。

@RestController
@RequestMapping("api/team")
@CrossOrigin(origins = "http://localhost:8081")
public class TeamController {
    @Autowired
    TeamService teamService;

    @PostMapping
    public ResponseEntity<?> addNewTeam(@RequestBody Team newTeam) {
        Team team = new Team();
        try {
            team= teamService.addNewTeam(newTeam);
        } catch(TeamAlreadyExistException e) {
            return new ResponseEntity<>(e.getMessage(), HttpStatus.BAD_REQUEST);
        }
        return new ResponseEntity<>(team, HttpStatus.OK);
    }

    @GetMapping
    public ResponseEntity<?> getAllTeams() {
        List<Team> teams = teamService.getAllTeams();
        return new ResponseEntity<>(teams, HttpStatus.OK);
    }
    
}

如果我在我的项目中有一个这样的控制器，并且只使用cmd curl本身，我就可以得到我想要的结果..就像下面这样..

MyPath>curl -X GET "http://localhost:8081/api/team"
[{"id":1,"name":"team3"}]

我试着不使用Postman，而是尝试使用HttpClient类和Cmd..我想如果我有@RestController和cmd.. http请求只是在没有HttpClient的情况下查找..有没有什么方法可以在尝试对我的TeamController进行Http请求调用时合并HttpClient？
