UAC10011002

Error message

找不到用户,loginName=%s

What it means

loginAfter performs post-login processing: it resolves the user by loginName via uacUserService.findByLoginName. If no user matches it throws UacBizException(UAC10011002) "找不到用户,loginName=%s". This usually means the session carried a loginName that no longer maps to an existing account.

Solutions

1. Verify the loginName exists (findByLoginName) before invoking loginAfter; invalidate the session if not.
2. Clear stale session/Redis token data after database resets or user deletions so dead loginNames aren't replayed.
3. Catch UacBizException UAC10011002, force logout, and redirect the user to re-authenticate.

Example fix

// before
uacLoginService.loginAfter(request, loginName); // stale session name
// after
UacUser user = uacUserService.findByLoginName(loginName);
if (user == null) {
    sessionService.invalidate(sessionId);
    throw new AuthException("session references deleted user; please re-login");
}
uacLoginService.loginAfter(request, loginName);

UacUser user = uacUserService.findByLoginName(loginName);
if (user == null) {
    // invalidate session/token and force re-login
}

null

try {
    uacLoginService.loginAfter(request, loginName);
} catch (UacBizException e) {
    if (ErrorCodeEnum.UAC10011002.getCode().equals(e.getCode())) {
        securityContext.logout();
        throw new AuthException("account no longer exists; please log in again");
    }
    throw e;
}

When it happens

Trigger: Calling loginAfter (or hitting an endpoint that runs it) with a loginName stored in the session/token that no longer exists — account deleted after login, loginName renamed, or a stale/foreign cookie resolving to a nonexistent user.

Common situations: User deleted or renamed while their session token was still valid; Redis/session cache surviving a database reset or environment switch; SSO passing a loginName from an external directory that isn't synced into the uac user table.
