小编Mar*_*hel的帖子

我想要markAsDirty一个内部的所有控件FormGroup.

我正在使用arquillian为Tomcat 8上部署的JAX-RS/Jersey Webservice创建集成测试.

我正在尝试这样的POST请求:

E dummy = dummyFactory.manufacturePojo(getSubClassType());
dummy.setId(null);

Client client = ClientBuilder.newClient();
WebTarget target = client.target(BASE_URI).path("bandeira");

Response response = target.request(MediaType.APPLICATION_JSON)
            .header(HttpHeaders.AUTHORIZATION, CHAVE_TESTE)
            .header(HttpHeaders.CONTENT_TYPE, "application/json")
            .post(Entity.entity(dummy, MediaType.APPLICATION_JSON));

当我这样做时,我得到这个例外:

我可以使用一些启发式,因为我还在学习arquillian和Jersey客户端API :)谢谢

假设我们有一个名为Comp的Component 和两个名为P1和P2的 @Injectable提供者.

P1需要P2的实例.

P1注入Comp

如果我在Comp上声明两个提供程序,那就完美了,就像这样:

@Component ({
    providers: [P1, P2]
})
export class Comp { ... }

现在我想做的是声明P1直接在P1内部需要P2:

@Component ({
    providers: [P1]
})
export class Comp { ... }


@Injectable(/** Inject P2 here **/)
export class P1 { ... }

谢谢你的帮助.

我有以下结构:

@Decorator
public abstract class MyDecorator<T extends BaseEntity, Q extends QueryParams> implements EntityService<T, Q> {

    @Any
    @Inject
    @Delegate
    EntityService<T, Q> delegate;

    @Override
    public T save(T entity) { ... }

} 

这是EntityService接口声明:

public interface EntityService<T extends BaseEntity, Q extends QueryParams> {

    T save(T entity);

    void deleteById(Integer id);

    void deleteAllById(List<Integer> ids);

    void delete(T entity);

    void deleteAll(List<T> entities);

    T findById(Integer id);

    QueryResultWrapper<T> query(Q parameters);

    Long count(Q parameters);

}

不幸的是,装饰器保存方法永远不会被调用,虽然没有显示错误...我得到它的唯一方法是这样:

@Decorator
public abstract class MyDecorator<T extends BaseEntity> implements EntityService<T> { ... } …

我想创建一个具有初始行为的AbstractComponent,同时能够在需要时覆盖它,可能吗？这是一个好习惯吗？

应该看起来或多或少那样:

export abstract class AbstractComponent implements OnInit {

  constructor(authService: AuthService, router: Router) {}

  ngOnInit() {
    if (authService.userNotLoggedInAnymore()) {
      router.navigate(['Login']);
    }
  }

  ...
}

我已经创建AbstractActivity并AbstractFormActivity删除了一些样板代码,它们的内容可能与问题无关,但无论如何我都会发布它,也许我误解了一些东西,它们是:

public abstract class AbstractActivity extends ActionBarActivity {

    protected ObjectGraph graph;

    @Inject
    public Bus bus;

    @Inject
    public App app;

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
        setContentView(getLayout());
        setupInjection();
    }

    public void setupInjection() {
        graph = ((App) getApplication()).createScopedGraph(getModule());
        graph.inject(this);
        bus.register(this);
        ButterKnife.inject(this);
    }

    protected abstract Object getModule();
    protected abstract int getLayout();
}

和

public abstract class AbstractFormActivity<T extends EntidadeBase> extends AbstractActivity implements Form<T> {

    protected T entity;
    protected Map<View, Boolean> formValidations;
    protected AbstractFormActivity() {
       formValidations …

我有一些字段需要在发送到服务器端之前进行格式化.

所以,我想使用自定义序列化程序序列化我的打字稿类的一些字段,这样的理想选择:

export class Person {
    @serializeWith(MyDateSerializer)
    private date: Date;
}

post(url, value) {
    this.http.post(url, JSON.stringfy(value, (key, val) => {
       if (//value has serializeWith annotation) {
           return //serialize with custom serializer
       }
    }));
}

任何接近这一点都是可以接受的,欢迎任何帮助.谢谢

我有这个docker-compose.yml文件

version: '3'

volumes:
  jenkins_home:

services:

  registry:
     image: registry:2
     ports:
       - "5000:5000"

  jenkins:
    image: jenkins/jenkins
    ports:
      - "9090:8080"
    volumes:
      - jenkins_home:/var/jenkins_home

正如您所看到的，有一个名为 的命名卷jenkins_home，现在我想知道数据真正保存在哪里？

运行docker inspect infra_jenkins我得到这个：

 ...
 "Mounts": [
    {
      "Type": "volume",
      "Source": "infra_jenkins_home",
      "Target": "/var/jenkins_home",
      "VolumeOptions": {
      "Labels": {
      "com.docker.stack.namespace": "infra"
              }
          }
      }
],
...

我使用命令在本地 docker swarm 集群上运行这些服务docker stack deploy，该集群由三个 VirtualBox 实例组成。

使用新安装的ionic2处理新项目,安装angular2-jwt后我收到此错误:

ParseError: 'import' and 'export' may appear only with 'sourceType: module'

D:\desenv\arquivos\workspace_inbit\medipop-parent\medipop-app\node_modules\angular2-jwt\angular2-jwt.ts:1
import {Injectable, Injector} from 'angular2/core';

重现:

ionic start testapp --v2 --ts 
cd testapp
npm i --save angular2-jwt

和应用页面:

@App({
    templateUrl: 'build/app.html',
    providers: [
        provide(AuthHttp, {
            useFactory: (http) => {
                return new AuthHttp(new AuthConfig({
                    headerPrefix: '',
                    noJwtError: true
                }), http);
            },
            deps: [Http]
        })
    ]
})
class MyApp {}

有没有人知道如何解决这个小谜题？

我希望我的工具栏使用材料设计径向反应编排指南来改变颜色

我想将它实现为一个有角度的2转换,但我不知道如何做到这一点:

它看起来像这样..

@Component({
 ...
  animations: [
    trigger('heroState', [
    state('inactive', style({
      backgroundColor: '#eee',
      transform: 'scale(1)'
     })),
     state('active',   style({
       backgroundColor: '#cfd8dc',
       transform: 'scale(1.1)'
     })),
     transition('inactive => active', animate('100ms ease-in')),
     transition('active => inactive', animate('100ms ease-out'))
   ])
  ]
})
