Aikau服务加载错误，为什么服务javascript文件没有正确找到或加载？

Question

我在向基于aikau的网页添加自定义小部件和服务时遇到了问题。在我看来，它不能正确加载模型。但我不明白原因。它正确地包含了(从我所能看到的.？)，并且它在语法上是正确的javascript (我或多或少地复制和削减了一个教程)，并从一个其他工作的Aikau页面调用。为什么它不起作用？

该项目驻留在一个全合一SDK项目中。我遵循了Aikau小部件的alfresco页面上的说明：https://docs.alfresco.com/5.2/concepts/dev-extensions-share-aikau-widgets.html

也就是说，定义一个.js文件，将其放置在正确的文件夹中(并创建一个扩展模块以指向其位置)。

实际内容(文件用于Aikau服务的目的)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，只要不包括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"
            }
        }
    ]
}; 

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

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.");
        },
    });
});

这个结果令我费解。首先，无论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，我会得到错误消息。

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

我肯定漏掉了什么，但是什么？

Answer 1

鉴于帖子不能被删除，而且我发现了这个错误的原因，我认为应该回答我自己的问题。

这个问题有几个原因。首先，扩展模块小部件的定位值是错误的。至少对我来说，教程错误地说明了这一点。他们想要的是

<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。这是第二个原因。当我检查活动包时，已经有一个名为示例的包，还有另一个位置。一定要确保你也改了名字，不要像我那样懒洋洋地坚持“示例”或“教程”。

第三个原因是我把小部件文件放在了错误的位置。

ProcessService.js，位于

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

应该实际定位在

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

只是我读得太快了。在文档页面中，指定了应该在何处部署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。

由此得出结论；

1. 确保您有正确的指定位置。
2. 一定要给每件事取一个唯一的名字。
3. 确保将文档指定的文件放在其中。

哇哦。我想都是这样的。希望下一个人能找到有用的东西。
