Error message

找不到绑定的用户, userId=%

What it means

While binding each selected user, bindUacUser4Group queries the user via uacUserService.queryByUserId(userId). If a user id does not resolve to an existing UacUser it throws UacBizException(UAC10011024) "找不到绑定的用户, userId=%" (bound user not found). Note the loop means earlier inserts already succeeded, so the transaction context matters.

Solutions

Validate all userIds exist (batch query) before invoking bindUacUser4Group so nothing is half-bound.
Remove stale ids from userIdList and retry; refresh the user list from the server.
Catch UacBizException UAC10011024; if the service is not transactional, clean up already-inserted UacGroupUser rows before retrying.

Example fix

// before
req.setUserIdList(userIds); // may contain deleted users
uacGroupService.bindUacUser4Group(req, loginAuthDto);
// after
List<UacUser> found = uacUserService.listByUserIds(userIds);
List<Long> validIds = found.stream().map(UacUser::getId).collect(Collectors.toList());
if (validIds.size() != userIds.size()) {
    throw new BusinessException("some users no longer exist; refresh selection");
}
req.setUserIdList(validIds);
uacGroupService.bindUacUser4Group(req, loginAuthDto);

Defensive patterns

Strategy: validation

Validate before calling

Map<Long, UacUser> found = uacUserService.listByUserIds(req.getUserIdList()).stream()
    .collect(Collectors.toMap(UacUser::getId, u -> u));
List<Long> missing = req.getUserIdList().stream().filter(id -> !found.containsKey(id)).collect(Collectors.toList());
if (!missing.isEmpty()) {
    throw new BusinessException("users not found: " + missing);
}

Type guard

null

Try / catch

try {
    uacGroupService.bindUacUser4Group(req, loginAuthDto);
} catch (UacBizException e) {
    if (ErrorCodeEnum.UAC10011024.getCode().equals(e.getCode())) {
        return ResponseEntity.status(404).body("a selected user no longer exists; refresh the user list");
    }
    throw e;
}

Prevention

Batch-verify all user ids before binding instead of relying on the per-row check.
Refresh user lists from the server immediately before batch operations.
Run the bind inside a transaction so partial inserts roll back on failure.

When it happens

Trigger: userIdList containing a stale or foreign user id — user deleted concurrently, id copied from another environment, or client sending user codes instead of numeric ids.

Common situations: Race where the user account is deleted between listing and binding; test fixtures referencing non-seeded users; environments (dev/staging) with divergent user tables.
