获取在 magnolia cms 中执行的自定义操作的节点名称

Question

我在 magnolia cms 中创建了一个名为 MyAction 的自定义操作。我想获取执行操作的页面的节点名称。相反，我得到一个空字符串作为页面名称。

这是代码：

package ch.xxx.module.versioning;

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

import javax.jcr.LoginException;
import javax.jcr.RepositoryException;
import javax.jcr.Session;

import info.magnolia.context.Context;
import info.magnolia.context.MgnlContext;



public class MyAction implements Action  {


    @Override
    public void execute() throws ActionExecutionException {
        String nodeName= "null";

        Context context = MgnlContext.getInstance();
        Session session = null;
        try {
            session = context.getJCRSession("website");
        } catch (LoginException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (RepositoryException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        //Get root node
        try {
            nodeName = session.getRootNode().getName();
        } catch (RepositoryException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        System.out.println("Executed MyAction for node: " + nodeName);
    }
}

Answer 1

您可以拥有一个构造函数并将 info.magnolia.ui.vaadin.integration.jcr.JcrNodeAdapter 作为 c-tor 参数注入。

谢谢@Ducaz035！

以下是适用于自定义操作的解决方案：

public class MyAction extends AbstractMultiItemAction<zzzVersioning>  {


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



@Override
public void execute() {
    try {
        System.out.println("Ran execute Action! " + getItems().get(0).getJcrItem().getName());
    } catch (RepositoryException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}



@Override
public void executeOnItem(JcrItemAdapter item) throws Exception {
    // TODO Auto-generated method stub

}



@Override
protected String getSuccessMessage() {
    // TODO Auto-generated method stub
    return null;
}



@Override
protected String getFailureMessage() {
    // TODO Auto-generated method stub
    return null;
}

}

这是自定义操作定义的代码：

public class zzzVersioning extends CommandActionDefinition {

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