以管理员身份运行Alfresco Java代码 [英] Run Alfresco Java code as Administrator

问题描述

我正在尝试执行一项操作，在该操作中，我将向所有父节点添加权限。但是，我需要以 admin 身份运行以管理权限。目前，我的代码如下：

I'm trying to implement an action in which I will add permissions to all parent nodes. However, I need to run as admin to manage the permissions. Currently my code looks like this:

        permissionService = serviceRegistry.getPermissionService();
        //Read the username of the current user
        final String loggedInUser = authenticationService.getCurrentUserName();

        ChildAssociationRef childAssociationRef = nodeService.getPrimaryParent(actionedUponNodeRef);

        //Get the parent NodeRef
        NodeRef parent = childAssociationRef.getParentRef();
        String fileName = (String) nodeService.getProperty(parent, ContentModel.PROP_NAME);

        //Iterate till you get to document library
        while(!fileName.contains("documentLibrary")){
            ChildAssociationRef childAssociationRef2 = nodeService.getPrimaryParent(parent);
            parent = childAssociationRef2.getParentRef();
            //Have to declare a final variable in order to access it in the RunAsWork
            final NodeRef ref = parent;

            fileName = (String) nodeService.getProperty(parent, ContentModel.PROP_NAME);

            RunAsWork<?> raw = new RunAsWork<Object>() {
             public Object doWork() throws Exception {
                 //Set permission to this folder for the logged in user
                 permissionService.setPermission(ref, loggedInUser, PermissionService.CONTRIBUTOR, true);
                 return null;
                }   
            };
            //Run as admin
            AuthenticationUtil.runAs(raw, "admin");
        }

我得到的例外很明显：
严重：04210027访问被拒绝。您没有执行此操作的适当权限。

The exception that I get is pretty obvious: SEVERE: 04210027 Access Denied. You do not have the appropriate permissions to perform this operation.

有什么建议吗？
谢谢

Any suggestions? Thanks

推荐答案

要详细了解Krutik的答案，您应该将代码包装在runAsSystem块中，如下所示：

To detail the answer from Krutik, you should wrap code in a runAsSystem block like this:

final permissionService = serviceRegistry.getPermissionService();
//Read the username of the current user
final String loggedInUser = authenticationService.getCurrentUserName();

ChildAssociationRef childAssociationRef = nodeService.getPrimaryParent(actionedUponNodeRef);

//Get the parent NodeRef
NodeRef parent = childAssociationRef.getParentRef();
String fileName = (String) nodeService.getProperty(parent, ContentModel.PROP_NAME);

//Iterate till you get to document library
while(!fileName.contains("documentLibrary")){
    ChildAssociationRef childAssociationRef2 = nodeService.getPrimaryParent(parent);
    parent = childAssociationRef2.getParentRef();
    //Have to declare a final variable in order to access it in the RunAsWork
    final NodeRef ref = parent;

    fileName = (String) nodeService.getProperty(parent, ContentModel.PROP_NAME);

    AuthenticationUtil.runAsSystem(new AuthenticationUtil.RunAsWork<Object>() {
      public Object doWork() throws Exception {
       permissionService.setPermission(ref, loggedInUser, PermissionService.CONTRIBUTOR, true);
       return "";
      }

    });
}
