Alfresco Aikau 服务加载错误，为什么没有正确找到或加载服务 javascript 文件？

Question

我在向基于 aikau webscript 的页面添加自定义小部件和服务时遇到问题。在我看来，它无法正确加载模型。但我无法理解其中的原因。它被正确地包含（从我所看到的..？），并且它在语法上是正确的 javascript（我或多或少地复制并删减了教程），并且从其他工作的 Aikau 页面调用。为什么它不起作用？ :(

该项目位于一个一体化 SDK 项目中。我已经按照 Aikau 小部件的露天页面上的说明进行操作： https://docs.alfresco.com/5.2/concepts/dev-extensions-share-aikau-widgets.html

即定义一个.js文件，将其放置在正确的文件夹中（，并创建指向其位置的扩展模块。

实际内容（该文件用于 Aikau 服务）基于 Aikau github 教程中的占位符服务： https://github.com/Alfresco/Aikau/blob/master/tutorial/chapters/Tutorial7.md

扩展模块

<module>
            <id>Company Aikau Widgets</id>
            <version>1.0.1</version>
            <auto-deploy>true</auto-deploy>
            <configurations>
                <config evaluator="string-compare" condition="WebFramework"
                    replace="false">
                    <web-framework>
                        <dojo-pages>
                            <packages>
                                <package name="example"
                                    location="js/company" />
                            </packages>
                        </dojo-pages>
                    </web-framework>
                </config>
            </configurations>
        </module>

页面 (helloworld2.get.js) 内容，只要不包含 ProcessService 就可以正常工作。

model.jsonModel = {
    services: [
        "alfresco/services/ActionService",
        "company/services/ProcessService"
   ],
    widgets: [
        {
            id: "SET_PAGE_TITLE",
            name: "alfresco/header/SetTitle",
            config: {
                title: "Process\u00F6versikt"
            }
        },
        {
            name: "alfresco/buttons/AlfButton",
            config: {
                label: "HELLO BUTTON",
                iconClass: "alf-folder-up-icon",
                publishTopic: "SEARCH_BUTTON_PRESS"
            }
        }
    ]
};

ProcessService.js，位于 share-jar-project/src/main/resources/alfresco/web-extension/site-data/extensions/js/company/services/

define(["dojo/_base/declare",
        "alfresco/core/Core",
        "dojo/_base/lang"],
        function(declare, Core, lang) {   
        return declare([Core], {    

            constructor: function tutorial_UserAndGroupService__constructor(args) {
            lang.mixin(this, args);
            this.alfSubscribe("SEARCH_BUTTON_PRESS", lang.hitch(this, this.runWebscript));
        },

        runWebscript: function tutorial_UserAndGroupService__getGroups(payload) {
            console.log("service works.");
        },
    });
});

结果让我很困惑。首先，无论该服务是否实际包含在页面中，我都会收到一条错误消息（在登录页面加载期间）：

其次，当我尝试加载实际页面时，我收到了错误消息

2019-08-02 09:32:32,706  ERROR [extensions.surf.DependencyAggregator] [http-bio-8080-exec-2] Could not find compressed file: /company/services/ProcessService.js

我一定是漏掉了什么，但是什么？

Answer 1

看到帖子无法删除，我找到了这个错误的原因，我想应该回答我自己的问题。

导致此问题的原因有多种。首先，扩展模块小部件位置值错误。至少对我来说，教程错误地指定了它。他们想要像

这样的东西吗

<package name="example" location="js/company" />

应该是这样的

<package name="company" location="resources/maven-sdk-tutorial-share-jar/js/company"/>

注意我更改了包名称。这是第二个原因。当我检查活动包时，已经有一个名为 example 的包，在另一个位置。始终确保您也更改名称，不要像我那样懒惰地坚持使用 "example" 或 "tutorial".

第三个原因是我把插件文件放在了错误的位置。

位于

的ProcessService.js

share-jar-project/src/main/resources/alfresco/web-extension/site-data/extensions/js/company/services/

实际上应该位于

/share-jar-project/src/main/resources/META-INF/resources/share-jar-project/js/omicron/services/

这只是我读得太快了。在文档页面中指定了应该部署的地方 https://docs.alfresco.com/5.2/concepts/dev-extensions-share-aikau-widgets.html 我将小部件放在扩展模块的路径中，这显然是错误的。

所以总结一下；

确保您指定的位置正确
确保你给所有的东西一个唯一的名字
确保将文件放在文档指定的位置

呸。我想这就是全部。希望下一个人会觉得这很有用。

Alfresco Aikau 服务加载错误，为什么没有正确找到或加载服务 javascript 文件？
