Error message

ErrorCodeEnum.UAC10011025

What it means

UacBizException with ErrorCodeEnum.UAC10011025 ("用户已存在, loginName=%") is thrown by UacUserServiceImpl.saveUacUser when creating a new user whose loginName already exists in the uac_user table. The service queries uacUserMapper.selectCount with the given loginName and aborts the insert if count > 0, because loginName must be unique.

Solutions

1. Check loginName availability with a selectCount query (or the user-exists API) before calling saveUacUser
2. Catch UacBizException and check getCode()==10011025, then prompt the user to choose a different loginName
3. Make registration idempotent: on duplicate, fetch the existing user and treat it as success if it belongs to the same source
4. Uniqueness-enforce loginName at the DB level (unique index) so races cannot create duplicates

Example fix

// before
uacUserService.saveUacUser(user, initPwd, authResDto);
// after
UacUser q = new UacUser();
q.setLoginName(user.getLoginName());
if (uacUserMapper.selectCount(q) > 0) {
    throw new BusinessException("登录名已被占用，请更换");
}
uacUserService.saveUacUser(user, initPwd, authResDto);

UacUser q = new UacUser();
q.setLoginName(loginName);
boolean exists = uacUserMapper.selectCount(q) > 0;
if (exists) { throw new BusinessException("loginName already taken"); }

try {
    uacUserService.saveUacUser(user, initPwd, authResDto);
} catch (UacBizException e) {
    if (e.getCode() == 10011025) { /* duplicate loginName: prompt user */ }
    else throw e;
}

When it happens

Trigger: Calling saveUacUser (or the REST/MQ wrappers around user registration) with a loginName that already matches an existing row in the uac_user table.

Common situations: Duplicate user registration (double form submit), re-running an import/seed script without idempotency, re-registering a deleted-but-soft-retained account, or a client retrying after a timeout when the first request actually succeeded.
