小编bal*_*man的帖子

我有一个AppComponent包含的列表ShapeComponents。我实现了一些部件延伸的ShapeComponent喜欢LineComponent，CircleComponent，RectangleComponent。他们每个人都有自己ng-template的#shapeTemplate。在我的app.component.html我要遍历列表ShapeComponents并显示每个ng-template（从LineComponent，CircleComponent等等）。

所以我有

shapes: ShapeComponent[] = []

其中包含LineComponent，CircleComponent等

我想要这样的事情

<div *ngFor="let shape of shapes">
    <!-- How to display the ng-template from for example LineComponent or Circle -->
</div>

我认为使用@ViewChildren或@ContentChildren会很有用，但不知道如何处理

我有使用artifactory和jenkins的问题.请参阅下面的错误日志.

我的版本詹金斯:1.638我的神器版本:3.9.2

Artifactory工作正常,还在jenkins中安装了插件并进行了配置.所有似乎都工作正常,但当我想建立一个项目时,我有以下错误.

我创建了一个 Hazelcast 管理器，它使用 spring、hibernate、jpa。我可以启动我的 hazelcast 实例。

我遇到的问题是我不知道如何使用 spring config 配置 hazelcast 客户端。我想在其他一些服务器组件中使用一个hazelcast-client

我真的不知道如何开始

任何帮助，将不胜感激

下面是我的 Hazelcast 服务器的 spring 配置
