Error message

该组织下还存在子节点，不能将其删除, Pid=%s

What it means

UAC10015007 ("该组织下还存在子节点，不能将其删除, Pid=%s") is thrown by deleteUacGroupById when the target group still has child organizations (uac_group rows with pid = id). Deleting would orphan the subtree, so it is refused.

Solutions

  1. Delete or move all child organizations first, then delete the parent
  2. Catch UacBizException UAC10015007 and show the child count / prompt to handle children first
  3. Use a cascade-delete API (if provided) that removes the subtree in order when that is the intent

Example fix

// before
uacGroupService.deleteUacGroupById(parentId);
// after
List<UacGroup> children = uacGroupService.getChildGroups(parentId); // or query pid = parentId
for (UacGroup child : children) {
    uacGroupService.deleteUacGroupById(child.getId()); // delete leaves first
}
uacGroupService.deleteUacGroupById(parentId);
Defensive patterns

Strategy: validation

Validate before calling

List<UacGroup> children = uacGroupMapper.select(new UacGroup().setPid(groupId));
if (!children.isEmpty()) { throw new IllegalStateException("Group has " + children.size() + " children; delete them first"); }

Try / catch

try {
    uacGroupService.deleteUacGroupById(groupId);
} catch (UacBizException e) {
    if (ErrorCodeEnum.UAC10015007.getCode().equals(e.getCode())) { /* show child groups, offer cascade or move */ }
    else throw e;
}

Prevention

When it happens

Trigger: Calling deleteUacGroupById(id) where uacGroupMapper.select(childGroup with pid=id) returns a non-empty child list.

Common situations: Deleting a parent department instead of the intended leaf; UI tree not expanding children so hidden sub-organizations exist; data imported with hierarchy the user is unaware of.
