会话HTTP - Spring和Angular 2-Java 学习之路

我在向Spring启动应用程序添加身份验证功能时遇到问题 . 我已经实现了如下的会话模式 .

AdminSession.java

@Component
@Scope(value="session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class AdminSession {
private final String id = UUID.randomUUID().toString();
private Admin admin;

public String getId() {
    return id;
}

public Admin getAdmin() {
    return admin;
}

public void setAdmin(Admin admin) {
    this.admin = admin;
}
}

AdminController.java

@RequestMapping("/admin")
@CrossOrigin
@RestController
public class AdminController extends RestAbstractController<Admin, AdminService>{
@Autowired
private AdminService adminService;
@Autowired
private AdminSession adminSession;


@RequestMapping(value="/auth",method=RequestMethod.POST)
public ResponseEntity<Admin> auth(
@RequestParam("pseudo") String pseudo, 
@RequestParam("password") String password,
){
Admin a = this.adminService.auth(pseudo, password);
if(a instanceof Admin) {
this.adminSession.setAdmin(a);
System.out.println("[DEBUG] Login "+this.adminSession.getAdmin());
this.displaySessionInfo();
}else System.err.println("[ERROR] a is not Admin instance");
return new ResponseEntity<Admin>(a,HttpStatus.ACCEPTED);
}

public Admin add(@RequestBody Admin admin){
if(!this.adminService.exist(admin.getPseudo())){
return super.add(admin);
}else return new Admin();

}

@RequestMapping("/isAuth")
public Admin isAuth(){

this.displaySessionInfo();
return this.adminSession.getAdmin();

}

private void displaySessionInfo(){
System.out.println("[DEBUG] Session info : "+this.adminSession.getId()+" "+this.adminSession.getAdmin()+" "+this.adminSession.toString());
}


}

问题是，当我尝试连接到Angular端时，Spring会在会话中正确地保存用户 . 但是当我在登录后尝试访问URL'/ admin / isAuth'时，会话不一样 .

控制台日志

2017-05-03 19:08:52.258  INFO 756 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet        : FrameworkServlet 'dispatcherServlet': initialization completed in 124 ms

Side Angular 2

Admin.service.ts

auth(pseudo:string,password:string):Observable<Admin>{
let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded;' });
let options = new RequestOptions({ headers: headers });
return this.http.post(this.provider.getURL()+"/admin/auth","pseudo="+pseudo+"&password="+password,options)
.map(this.extractData);
}

submit(){
    this.process=true;
    this.adminService.auth(this.pseudo,this.password).subscribe(t=>{
      this.adminService.isAuth();
      this.process=false;
      this.adminService.isAuthentified = true;
      this.provider.tokenSession = t;
      this.adminService.isAuth().subscribe(t=>console.log("Test login"));
      this.router.navigate(['/']);
    },err=>console.error(err));
  }

为什么我丢失了我的http会话？

谢谢您帮忙 .

AdminService.java

@Service
public class AdminService extends RestAbstractService<Admin, AdminRepository>{

    @Autowired
    private AdminRepository adminRepository;

    public Admin auth(String pseudo, String password, AdminSession adminSession){
        Admin a = this.adminRepository.findAdminByPseudo(pseudo);
        if(a instanceof Admin)
            if(a.getPassword().equals(password)) {
                adminSession.setAdmin(a);
                a.setPassword(null);
                return a;
            }
            else return null;
        else if(pseudo.equals("root") & Admin.root.getPassword().equals(password))
            return Admin.root;
        else return null;
    }

    public boolean exist(String pseudo){
        return this.adminRepository.findAdminByPseudo(pseudo) instanceof Admin;
    }

    public boolean isAuth(AdminSession adminSession){
        return adminSession.getAdmin() instanceof Admin;
    }


    public void logout(AdminSession adminSession){
        adminSession.setAdmin(null);
    }
}

Admin.service.ts

@Injectable()
export class AdminService {
  isAuthentified:boolean;
  constructor(private provider :ProviderService, private http:Http) { }

  auth(pseudo:string,password:string):Observable<Admin>{
    let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded;' });
    let options = new RequestOptions({ headers: headers });
    return this.http.post(this.provider.getURL()+"/admin/auth","pseudo="+pseudo+"&password="+password,options)
      .map(this.extractData);
  }

  isAuth():Observable<boolean>{    
    let headers = new Headers({ 'Content-Type': 'application/json;', 'token': this.provider.tokenSession.token});
    let options = new RequestOptions({ headers: headers });
    return this.http.get(this.provider.getURL()+"/admin/isAuth",)
        .map(this.extractBoolean);
  }

  private extractData(res: Response) {
    let body = res.json();
    return body;
  }

  private extractBoolean(res:Response){
    this.isAuthentified = res.text() === 'true';
    return this.isAuthentified;
  }


  private handleError (error: Response | any) {
    let errMsg: string;
    if (error instanceof Response) {
      const body = error.json() || '';
      const err = body.error || JSON.stringify(body);
      errMsg = `${error.status} - ${error.statusText || ''} ${err}`;
    } else {
      errMsg = error.message ? error.message : error.toString();
    }
    console.error(errMsg);
    return Observable.throw(errMsg);
  }

}

在“providerService”中，我有权访问Web服务Spring .

我发现了这个问题 . 我认为是Angular 2.对于eatch请求， Headers 需要'withCredentials';

export class MyService {
  private httpGetOptions : RequestOptions = new RequestOptions({ withCredentials: true });

  getSomeone (): Observable<any> {
    return this.http.get(url,this.httpGetOptions);
  }
}
