java - 自定义操作实现 Magnolia CMS

Question

我尝试在 Magnolia 中的页面应用程序的操作栏中实现自定义操作，类似于 Magnolia 6.0 custom action implementation .

我的实现是:

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");
    }
}

页面应用程序的操作配置使用类 ch.zzz.module.versioning.ZzzVersioning，我在页面应用程序的操作栏中的项目下列出了该操作。

配置应用程序模块>页面>应用程序>页面>子应用程序>浏览器>操作>MyActions-class=ch.zzz.module.versioning.ZzzVersioning

模块>页面>应用程序>页面>子应用程序>浏览器>操作栏>部分>pageActions>importExportActions>items-MyAction

当我单击操作栏中的 MyAction 时，收到一条错误消息:无法实例化操作的操作类:MyAction。

这是我在日志中得到的内容:

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

...然后在堆栈末尾:

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

有什么建议可以让它发挥作用吗？

解决方案感谢©Ducay035，我能够找到自定义版本控制类的解决方案:

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 类:

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
    }

您必须公开您的类(class)，以便 IOC 系统可以找到它。但是，如果您使用注入(inject)机制，则可以使构造函数成为非私有(private)的。

干杯，

希望有帮助
