Watch my Angular Front-end project

Now watch my Back-end Java project with Spring Boot

Don’t worry about my Back-end project, it’s working well, the problem is my Angular Front-end project, I’m trying to load a grid and I’m not succeeding because it’s generating an error in the Angular consoles, but rather look at the files I changed.

See my project running before the changes:

app.modules.ts file Before:

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    EstilosModule,
    CoreModule,
    CevejasModule,
    ClientesModule,
    UsuariosModule,

    BrowserAnimationsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

After the changes:

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    EstilosModule,
    CoreModule,
    CevejasModule,
    ClientesModule,
    UsuariosModule,
    HttpModule,
    BrowserAnimationsModule
  ],
  providers: [EstiloService],
  bootstrap: [AppComponent]
})
export class AppModule { }

Stilopesquisacomponent file Before:

export class EstiloPesquisaComponent {

}

After the changes:

export class EstiloPesquisaComponent implements OnInit{


estilos = [];
constructor(private estiloService: EstiloService){ }

ngOnInit() {
     this.pesquisar();
  }
  pesquisar() {
     this.estiloService.pesquisar()
       .then(estilos => this.estilos = estilos);
   }

}

I think my problem is in this code below:

Arquivo Stiloservice

Before:

@Injectable()
export class EstiloService {

}

After the changes:

@Injectable()
export class EstiloService {

  estilosUrl = 'http://localhost:8080/estilos';

  constructor(private http: Http) { }

  pesquisar(): Promise<any> {
    return this.http.get(`${this.estilosUrl}`)
    .toPromise()
    .then(response => {
        console.log(response.json());
        });
    }

}

After I make the changes it generates this error:

 @ ./src/app/app.module.ts 17:0-59
 @ ./src/main.ts
 @ multi webpack-dev-server/client?http://0.0.0.0:0 ./src/main.ts

I believe the problem is in the file Stiloservice.

Could someone check where I went wrong please?

Following the suggestion of @André Roggeri Campos

made the suggested changes, but generated this error:

ERROR in src/app/estilos/estilo.service.ts(2,10): error TS2305: Module '"C:/Users/Wladimir/Desktop/projeto cervejaria/brewer-ui/node_modules/@angular/http/src/http_module"' has no exported member 'Http'.

didn’t work!

One of your Times seems to be wrong.

I have noticed that many times the Visual Code Intelisense imports the Angular modules incorrectly.

Replace the @angular/http/src/http_module for @angular/http

gave a different error, I think the problem is not the import.

if you check this github model and design it did the same import &#Xa

fix the problem, the problem was importing the module file, I switched this import { Httpmodule } from '@angular/http/src/http_module'; import { Httpmodule } from '@angular/http'; but anyway your tip helped, thank you very much.
