Javascript 我尝试从登录表单中获取信息，并将其更改为id

我有一个html的登录页面，我在那里得到用户名，密码和类型 当我登录到帐户时，我需要从用户注册时获得的id中查找帐户详细信息，但每次我收到此消息时，它都无法从“'java.lang.String'转换为所需的类型'long'”；我怎样才能解决这个问题？ 我的登录方法返回long，这是id类型

代码如下：

public class LoginController {

    @Autowired
    LoginServiceImpl loginService;

    @GetMapping("/login/{userName}/{password}/{clientType}")
    public long Login(@PathVariable("userName") String userName,@PathVariable("password") String password,
            @PathVariable("clientType") ClientType clientType)throws CustomException {
        return loginService.login(userName, password, clientType);}

public long login(String userName, String password, ClientType clientType) throws CustomException {
    if(clientType.equals(ClientType.ADMIN)) {
        adminService.login(userName, password, clientType);
        System.out.println("admin loged in");

    }
    else if(clientType.equals(ClientType.COMPANY)) {
        Company companyLogin = companyRepository.findByCompName(userName);
        companyService.login(userName, password, clientType);
        System.out.println("company loged in");
        return companyLogin.getId();
    }
    else if(clientType.equals(ClientType.CUSTOMER)) {
        customerService.login(userName, password, clientType);
        System.out.println("customer loged in");
    }
    else {
        System.out.println("login didnt execute");
    }
    return 0;
}

    $scope.submit=function(){
$http.get("http://localhost:8080/rest/api/login/" +     $scope.username +"/" + $scope.password + "/" + $scope.cType).then(
    function(response){
        $scope.login = response.data;
        switch ($scope.cType){


            case "COMPANY":
                window.location.assign("http://localhost:8080/rest/api/company.html")
                break;

                $scope.hideAllTables();
                $scope.welcomePage = true;
                // $scope.MainMenu = true;
                $http.get('http://localhost:8080/rest/api/company.html/comanyDetailes/' + compny).then(function(response) {
                            $scope.company = response.data;
                            $scope.welcomePage = true;
                        }, function(error) {
                            alert('operation failed ', error.data);
                        });
