以管理員身份運行Alfresco Java代碼

Question

我正在嘗試執行一項操作，在該操作中，我將向所有父節點添加權限。 但是，我需要以管理員身份運行以管理權限。 目前，我的代碼如下所示：

        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");
        }

我得到的異常非常明顯： 嚴重：04210027訪問被拒絕。 您沒有適當的權限來執行此操作。

有什么建議么？ 謝謝

Answer 1

要詳細說明Krutik的答案，您應該將代碼包裝在runAsSystem塊中，如下所示：

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 "";
      }

    });
}

嘗試在戶外使用AuthenticationUtil.runAsSystem方法。

Answer 3

AuthenticationUtil.runAsSystem(() -> {
            // do your work
            return null;
 });
