我一直在尝试传播自定义角色布局的“查看”权限，对于该布局和该自定义角色，resourcepermission表中不存在任何条目。如下面的代码所示，布局权限应该使用
进行理想设置ResourcePermissionServiceUtil.setIndividualResourcePermissions(groupId, companyId, layout.getModelClassName(),
"primkey", roleIdsToActionIds);
但是，这里第一次调用有效，但第二次调用设置当前布局的父布局权限，它会出现错误日志中显示的错误。有人可以指导我如何实现这个目标吗？
// Propagete VIEW access to Page, on which Portlet is added - START
long plid = LayoutLocalServiceUtil.getDefaultPlid(groupId, false, portletId);
if(plid!=0){
Layout layout = LayoutLocalServiceUtil.getLayout(plid);
if(layout!=null){
_log.info("Adding permission for layout: "+layout+", layout model class name:"+layout.getModelClassName()+", scope:"+ResourceConstants.SCOPE_INDIVIDUAL
+", primkey:"+String.valueOf(plid)+", roleid:"+customRoleId+", actionid:"+ ActionKeys.VIEW);
Map<Long, String[]> roleIdsToActionIds = new HashMap<Long, String[]>();
List<String> actionIds = new ArrayList<String>();
actionIds.add(ActionKeys.VIEW);
roleIdsToActionIds.put(customRoleId, actionIds.toArray(new String[actionIds.size()]));
ResourcePermissionServiceUtil.setIndividualResourcePermissions(groupId, companyId, layout.getModelClassName(),
String.valueOf(plid), roleIdsToActionIds);
// TODO: give view permission to all its parent layouts as well
while(layout.getParentLayoutId()!=0){
layout = LayoutLocalServiceUtil.getParentLayout(layout);
_log.info("Adding permission for parent layout: "+layout+", layout model class name:"+layout.getModelClassName()+", scope:"+ResourceConstants.SCOPE_INDIVIDUAL
+", primkey:"+String.valueOf(layout.getPlid())+", roleid:"+customRoleId+", actionid:"+ ActionKeys.VIEW);
ResourcePermissionServiceUtil.setIndividualResourcePermissions(groupId, companyId, layout.getModelClassName(),
String.valueOf(layout.getPlid()), roleIdsToActionIds);
}
_log.debug("Added view permission for page of portlet:"+portletId);
}
} // Propagete VIEW access to Page, on which Portlet is added - END

答案 0 :(得分：1)
所以最后看起来这个API调用修复了我的问题。
ResourcePermissionLocalServiceUtil.setResourcePermissions(
companyId, Layout.class.getName(),
ResourceConstants.SCOPE_INDIVIDUAL,
String.valueOf(layout.getPlid()), customRoleId,
new String[] {
ActionKeys.VIEW
});
在尝试这个之前，我还尝试了其他两个Liferay API而没有成功。
ResourcePermissionLocalServiceUtil.setResourcePermissions(companyId, layout.getModelClassName(), ResourceConstants.SCOPE_INDIVIDUAL, String.valueOf(layout.getPlid()), roleIdsToActionIds);
和
ResourcePermissionServiceUtil.addResourcePermission(groupId, companyId, layout.getModelClassName(), ResourceConstants.SCOPE_INDIVIDUAL, String.valueOf(layout.getPlid()), customRoleId, ActionKeys.VIEW);
两者都失败了。
