UAC10012001

Error message

角色ID不能为空

What it means

IllegalArgumentException carrying message of UAC10012001 ('角色ID不能为空') thrown by UacRoleServiceImpl.deleteRoleById when roleId is null. Unlike the other errors in this family, a plain IllegalArgumentException is used; the null ID cannot identify a role to delete.

Solutions

1. Pass a valid roleId from the selected row
2. Validate the id request parameter before calling the service
3. Handle IllegalArgumentException in the controller and return a 'role id required' response

Example fix

// before
uacRoleService.deleteRoleById(request.getParameter("roleId") == null ? null : Long.valueOf(request.getParameter("roleId")));
// after
Long roleId = Long.valueOf(request.getParameter("roleId"));
uacRoleService.deleteRoleById(roleId);

if (roleId == null) {
    return Result.error("roleId is required");
}

boolean isDeletable(Long roleId) { return roleId != null && roleId > 0 && !Objects.equals(roleId, GlobalConstant.Sys.SUPER_MANAGER_ROLE_ID); }

try {
    uacRoleService.deleteRoleById(roleId);
} catch (IllegalArgumentException e) {
    return Result.error("角色ID不能为空");
}

When it happens

Trigger: Calling uacRoleService.deleteRoleById(null), e.g. a delete request whose id parameter was missing or failed binding.

Common situations: Delete button rendered without a role context; REST path variable omitted; stale UI state after the role was deleted by another user.
