Error message

ErrorCodeEnum.UAC10011001

What it means

UAC10011001 is thrown by UacRoleUserServiceImpl.deleteByUserId when the userId parameter is null. Deleting all role-user associations for a user requires the user id; a null would otherwise produce an unbounded delete, so the service rejects it immediately before touching the mapper.

Solutions

1. Ensure the user id is loaded/validated before invoking deleteByUserId
2. Add a null check on the user entity before the cascade delete
3. Skip or log-and-continue for records with a null userId in batch jobs
4. Verify the upstream user lookup succeeded (delete the user only after it is found)

Example fix

// before
UacUser user = uacUserService.getByUserCode(code);
uacRoleUserService.deleteByUserId(user.getId()); // NPE if user==null
// after
UacUser user = uacUserService.getByUserCode(code);
Preconditions.checkNotNull(user, "user not found: " + code);
uacRoleUserService.deleteByUserId(user.getId());

if (user == null || user.getId() == null) { throw new IllegalStateException("cannot delete roles for unknown user"); }

boolean isDeletableUser(UacUser user) { return user != null && user.getId() != null; }

try { uacRoleUserService.deleteByUserId(userId); } catch (UacBizException e) { if ("UAC10011001".equals(e.getCode())) { log.warn("skipped role-user delete: null userId"); return 0; } throw e; }

When it happens

Trigger: Calling deleteByUserId(null), typically inside a user-delete flow where the user object or its id was never loaded (e.g. user not found upstream and the null id propagated).

Common situations: Cascading user-deletion code that doesn't check the user lookup result, refactored callers that dropped an earlier null check, or batch jobs processing malformed records with missing user ids.
