我想将字符串值传递给angular2中的组件,但它不能与默认绑定一起使用.我在想类似的东西:

<component [inputField]="string"></component>

不幸的是,在赋值的右侧只允许表达式.有没有办法做到这一点？

输入 JSON：

{
  "some_field":"some value"
}

用于映射的类型：

{
  "some_field":"some value"
}

如何配置 JSON 和 TypeScript 类型之间的映射，以便 some_field -> someField？

我已经用返回SseEmitter的方法实现了控制器，现在我想对其进行测试。到目前为止，我能找到的唯一方法是：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = {SsePaymentReceivedController.class, AutomatBackendContextInitializer.class, EventBusImpl.class})
@WebAppConfiguration
public class SsePaymentReceivedControllerIntegrationTest {

@Inject
WebApplicationContext context;
@Inject
SsePaymentReceivedController sseCoinController;
@Inject
EventBusImpl eventBus;

MockMvc mockMvc;

@Before
public void setUpMockMvc() {
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context).build();
}

@Test
public void subscriptionToSseChannelIsFine() throws Exception {
    MvcResult result = mockMvc.perform(get("/sse/payment"))
            .andExpect(status().isOk())
            .andReturn();
    eventBus.fireNotification(new PaymentReceivedNotification("50", Currency.EURO));
    LinkedHashSet<ResponseBodyEmitter.DataWithMediaType> emitters =
            (LinkedHashSet<ResponseBodyEmitter.DataWithMediaType>)Whitebox.getInternalState(((SseEmitter)result.getModelAndView().getModel().get("sseEmitter")), "earlySendAttempts");
    final Iterator<ResponseBodyEmitter.DataWithMediaType> iterator = emitters.iterator();

    ResponseBodyEmitter.DataWithMediaType dataField = iterator.next();
    assertEquals("data:", dataField.getData());

    ResponseBodyEmitter.DataWithMediaType valueField = iterator.next();
    assertEquals("{\"remainingAmount\":\"50\",\"currency\":\"EURO\"}", valueField.getData());

    ResponseBodyEmitter.DataWithMediaType lastField = iterator.next();
    assertEquals("\n\n", lastField.getData());
}
}

必须有比检查返回模型的内部更好的方法，而我正在寻找-有什么想法吗？

单击组件的按钮时将执行以下方法.

async onClickButton() {
    await this.shoppingCartService.add(this.selectedOffer);
    this.router.navigate(['ShoppingCartComponent']);
}

数据将添加到购物车,但在导航到下一页时,只会呈现标题,而数据则不会.此方法有效,如果不使用async-await,将正确呈现以下页面.使用ChangeDetectorRef.detectChanges()和ApplicationRef.tick()强制更改检测无效.离开下一页即ShoppingCartComponent后,将进行渲染并暂时显示数据.什么想法可能会出错？

运行以下WebTestClient测试时

    @Test
    fun `test accepted response`() {
        standaloneSetup(SapKontraktEndpointV1())

        given()
            .body(
                "{}", ObjectMapperType.JACKSON_2
            )
            .contentType(ContentType.JSON)
        .`when`()
            .post("/api/v1/kontrakt/erstellen")
        .then()
            .statusCode(202)
    }

然后出现以下错误：

使用 4.2.0 测试运行成功。

我想通过服务帐户身份验证将iOS应用中的文件上传到Google云端存储分区,即未经用户同意.

https://code.google.com/p/google-api-objectivec-client/wiki/Samples上的示例不包含云存储项目.其中的示例仅在用户同意的情况下使用标准OAuth 2.0身份验证.

我所知道的是,GTLServiceStorage与GTLQueryStorage需要使用的,但验证部分尚不清楚.

我正在设置一个使用Angular2进行路由的规范.这是应用程序组件:

import {Component, View} from 'angular2/core';

import {RouteConfig, ROUTER_DIRECTIVES} from 'angular2/router';
import {Search} from './search/search';
import {SearchResults} from './search-results/search-results';

@Component({
     selector: 'my-app'
})
@View({
    template: `<div>
    <router-outlet></router-outlet>
     </div>`,
    directives: [ROUTER_DIRECTIVES]
})
@RouteConfig([
    {path: '/search', name: 'Search', component: Search, useAsDefault: true},
    {path: '/search-results', name: 'SearchResults', component: SearchResults}
])
export class App {
}

这是包含导航的搜索组件:

import {Component} from 'angular2/core';
import {Router} from "angular2/router";

@Component({
     template: '<div></div>'
})
export class Search {
    constructor(public router: Router) {}

    onSelect(station:Station):void {
        this.router.navigate(['SearchResults']);
    }
}

搜索结果组件:从"angular2/core"导入{Component};

@Component({ …

forwardRef-wrapped 组件似乎没有设置 ref，因为以下测试失败并出现此错误：

    Error: Uncaught [TypeError: Cannot read properties of null (reading 'focus')]

它在浏览器中工作，只是测试失败。

export const SelectFormItem = forwardRef(
  <VT extends SelectValue = SelectValue>(
    { name, label, rules }: Props<VT>,
    ref: React.Ref<RefSelectProps>

    return (

我刚刚使用 Maven 将几个项目升级到 Java 19、Spring Boot 3.0.2、Kotlin 1.8.0，我希望 Spring Boot 生成本机映像。

<java.version>19</java.version>
<kotlin.version>1.8.0</kotlin.version>

配置的相关部分spring-boot-maven-plugin是：

        <configuration>
          <image>
            <env>
              <BP_JVM_VERSION>19.*</BP_JVM_VERSION>
              <BP_NATIVE_IMAGE>true</BP_NATIVE_IMAGE>
              <BPE_APPEND_JAVA_TOOL_OPTIONS>-XX:+HeapDumpOnOutOfMemoryError -XX:MaxDirectMemorySize=64M</BPE_APPEND_JAVA_TOOL_OPTIONS>

            </env>
          </image>
        </configuration>

但是，当我使用以下命令构建其中一个项目时

mvn -Pnative spring-boot:build-image

使用以下 Gradle 设置

sourceCompatibility = 1.12
targetCompatibility = 1.12

tasks.withType(JavaCompile) {
    options.incremental = true
    options.compilerArgs

  |_main
  |_test
|_moduleB
  |_main
  |_test

这是日期格式设置程序：

let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .medium
dateFormatter.timeStyle = .medium

预期产量：

Aug 13, 2017 6:04:11 PM

电流输出：

Aug 13, 2017 at 6:04:11 PM

理想情况下，如何在不指定格式字符串的情况下删除“ at”一词，它来自何处？

在奥地利德语语言环境中：

dateFormatter.locale = Locale(identifier: "de_AT")
13.08.2017, 18:04:11

使用美国英语语言环境：

dateFormatter.locale = Locale(identifier: "en_US")
