自定義操作實施 Magnolia CMS

Question

我嘗試在 Magnolia 中的頁面應用程序的操作欄中實現自定義操作，類似於Magnolia 6.0 自定義操作實現。

我的實現是：

package ch.zzz.module.versioning;


import info.magnolia.ui.api.action.Action;
import info.magnolia.ui.api.action.ActionExecutionException;
import info.magnolia.ui.api.action.ConfiguredActionDefinition;

public class ZzzVersioning extends ConfiguredActionDefinition {

    public ZzzVersioning() {
        this.setImplementationClass(MyAction.class);
    }
}

class MyAction implements Action {



    @Override
    public void execute() throws ActionExecutionException {
        System.out.println("Hello! Executed MyAction");
    }
}

頁面應用程序的操作配置使用 class ch.zzz.module.versioning.ZzzVersioning 並且我在頁面應用程序的操作欄中的項目下列出了該操作。

配置應用程序模塊>頁面>應用程序>頁面>子應用程序>瀏覽器>操作>MyActions -class=ch.zzz.module.versioning.ZzzVersioning

modules>pages>apps>pages>subApps>browser>actionbar>sections>pageActions>importExportActions>items-MyAction

當我單擊操作欄中的 MyAction 時收到錯誤消息： Could not instantiate action class for action: MyAction.

這是我在日志中得到的：

2019-11-22 08:37:26,498 ERROR fo.magnolia.ui.contentapp.browser.BrowserPresenter: An error occurred while executing action [MyAction]
info.magnolia.ui.api.action.ActionExecutionException: Could not instantiate action class for action: MyAction

...然后在堆棧的末尾：

Caused by: info.magnolia.objectfactory.MgnlInstantiationException: No suitable constructor found for class [class ch.zzz.module.versioning.MyAction]

有什么建議如何讓它工作嗎？

解決方案感謝 ©Ducay035，我能夠找到自定義版本控制 class 的解決方案：

package ch.zzz.module.versioning;

import info.magnolia.ui.api.action.CommandActionDefinition;

/**
 * Definition interface for the MyAction page action.
 */

public class UzhVersioning extends CommandActionDefinition {

    public UzhVersioning() {
        this.setImplementationClass(MyAction.class);
    }
}

和 MyAction class：

public class MyAction extends AbstractMultiItemAction<Versioning>  {

    public MyAction(Versioning definition, JcrItemAdapter item, UiContext uiContext) {
        super(definition, item, uiContext);
        // TODO Auto-generated constructor stub
    }




    @Override
    public void execute() {
    ////your action code here
    }

您必須公開您的課程，以便 IOC 系統可以找到它。 但是，如果您使用注入機制，則可以使構造函數成為私有的。

干杯，

希望有幫助
