小编Pet*_*ann的帖子

我正在努力学习Angular 2.

我想使用@ViewChild Annotation 从父组件访问子组件.

这里有一些代码行:

在BodyContent.ts我有:

import {ViewChild, Component, Injectable} from 'angular2/core';
import {FilterTiles} from '../Components/FilterTiles/FilterTiles';


@Component({
selector: 'ico-body-content'
, templateUrl: 'App/Pages/Filters/BodyContent/BodyContent.html'
, directives: [FilterTiles] 
})


export class BodyContent {
    @ViewChild(FilterTiles) ft:FilterTiles;

    public onClickSidebar(clickedElement: string) {
        console.log(this.ft);
        var startingFilter = {
            title: 'cognomi',
            values: [
                'griffin'
                , 'simpson'
            ]}
        this.ft.tiles.push(startingFilter);
    } 
}

而在FilterTiles.ts中:

 import {Component} from 'angular2/core';


 @Component({
     selector: 'ico-filter-tiles'
    ,templateUrl: 'App/Pages/Filters/Components/FilterTiles/FilterTiles.html'
 })


 export class FilterTiles {
     public tiles = [];

     public constructor(){};
 } …

如何在运行时解决此错误mvn clean install？

我看到,从servlet-api我的磁盘上的本地存储库中没有创建任何包.

我的程序必须逐行读取文本文件.UTF-8中的文件.我不确定文件是否正确 - 可以包含不可打印的字符.是否可以检查它而不进入字节级别？谢谢.

在eclipse中,我可以在新的方法名称上移动鼠标,然后单击以创建新方法.我想知道如何使用Android studio(基于IntelliJ Idea)来实现它.

我正试图在eclipse中创建一个简单的插件.当我运行应用程序时,我在日志文件中看到此错误:

org.osgi.framework.BundleException:bundle org.xy的bundle org.xyActivator的激活器无效.

你对这个错误有任何想法吗？

我创建了一个gradle项目,一切都很好,但是当我尝试上传到我的Maven存储库时,我得到以下Gradle错误:

FAILURE: Build failed with an exception.

* What went wrong:
Could not evaluate onlyIf predicate for task ':library:signArchives'.
> Unable to read secret key from file: C:\Users\ideal\pubring.gpg (it may not be a PGP secret key ring)

我按照Sonatype的说明生成密钥,然后将其从生成的位置复制到上面列出的位置.我还发布了MIT密钥库的公钥.将gradle.properties在我的用户目录下的文件包含与钥匙串以下条目:

signing.keyId=MY_KEY_ID
signing.password=MY_KEY_PASSWORD
signing.secretKeyRingFile=C:\\Users\\ideal\\pubring.gpg

这是在Windows平台上.我已经尝试搜索错误消息,但唯一出现的是相关插件的源文件.

我最近切换到intellij进行scala开发.

我找不到以下快捷方式:

在eclipse中,我可以输入方法调用,例如

method("hello", 1)

并按下<command>1让eclipse弹出一个建议,让我创建一个方法存根.

intellij中有这样的捷径吗？

像下面一样,我跑步时出错了 mvn package

我想知道我是如何确定我的ItemWriter,Spring Batch当前是处于块处理模式还是处于后备单项处理模式.首先,我没有找到关于如何实现这种回退机制的信息.

即使我还没有找到解决我实际问题的方法,我想和你分享我对回退机制的了解.

如果我遗漏了任何内容,请随意添加附加信息的答案;-)

我在新的RSA for WebSphere Software安装中缺少"服务器视图".它在"窗口>显示视图>其他......"中也不可用.

有人有想法吗？我希望这个视图从一开始就可用.
