我通过以下方式升级到Angular 7.1.0：

"@angular/animations": "^7.1.0",
"@angular/cdk": "^7.1.0",
"@angular/common": "^7.1.0",
"@angular/compiler": "^7.1.0",
"@angular/core": "^7.1.0",
"@angular/forms": "^7.1.0",
"@angular/http": "^7.1.0",
"@angular/material": "^7.1.0",
"@angular/platform-browser": "^7.1.0",
"@angular/platform-browser-dynamic": "^7.1.0",
"@angular/router": "^7.1.0"

我正在使用Angular Material Expansion Panels，它们最初通过[expanded] =“ false”扩展为false。

扩展面板的主体在几毫秒内可见。从扩展到未扩展似乎只是一小段路程。有人有同样的问题吗？

<mat-expansion-panel-header>

  <mat-panel-title>
    <div class="NumberAccordionContentWrapper__centered">
      <h2 [class.NumberAccordion__notExpanded]="!isExpanded">{{ headline }}</h2>
    </div>
  </mat-panel-title>

</mat-expansion-panel-header>

<div class="NumberAccordionContentWrapper__centered">

  <ng-template tbHost></ng-template>

</div>

我正在尝试使用 Java 12 在本地主机上使用 Spring Boot 2.1.7.RELEASE 启动 Spring-Kafka。

获取错误：“org.apache.kafka.clients.NetworkClient : [Consumer clientId=consumer-1, groupId=inter] 无法建立到节点 -1 的连接。代理可能不可用。”

我尝试将 Java 版本切换到 11 和 8 以及各种属性

spring:
  kafka:
    consumer:
      #bootstrap-servers: localhost:9092
      group-id: inter
      auto-offset-reset: earliest
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
    producer:
      bootstrap-servers: localhost:9092

@Service
public class KafkaHalloWorldMessagingService {

    private KafkaTemplate<String, String> kafkaTemplate;

    @Autowired
    public KafkaHalloWorldMessagingService(KafkaTemplate<String, String> kafkaTemplate) {
        this.kafkaTemplate = kafkaTemplate;
    }

    public void sendHalloToTheSystem(String messageToSend) {
        kafkaTemplate.send("interlinked.hallo.topic", messageToSend);
    }
}

@Component
public class KafkaHalloWorldListener {

    @KafkaListener(topics = "interlinked.hallo.topics", groupId = "inter")
    public …
