{realnames}已存在该职位中

Error message

{realnames}已存在该职位中

What it means

Thrown by SysUserPositionServiceImpl when batch-adding users to a position. It collects userIds that already have a user-position row into userBuilder, then resolves their realnames and reports which users are already in the position.

Solutions

1. Filter the request client-side to exclude userIds already in the position before submitting.
2. On the server, treat already-present as idempotent success instead of error if business allows.
3. Check the returned realnames against the intended add list and retry with only the missing users.
4. Remove duplicate userIds from the request payload.

Example fix

// before: server throws on any existing user
addUsersToPosition(allUserIds, positionId);

// after: pre-filter existing members
List<String> existing = userPositionMapper.selectExistingUserIds(positionId);
List<String> toAdd = allUserIds.stream().filter(id -> !existing.contains(id)).collect(toList());
addUsersToPosition(toAdd, positionId);

List<String> existing = userPositionMapper.selectExistingUserIds(positionId);
List<String> toAdd = userIds.stream().filter(id -> !existing.contains(id)).collect(Collectors.toList());
if (toAdd.isEmpty()) return Result.ok("无新增用户");

boolean hasNewMembers(List<String> userIds, String positionId) {
  List<String> existing = userPositionMapper.selectExistingUserIds(positionId);
  return userIds.stream().anyMatch(id -> !existing.contains(id));
}

try { userPositionService.addUsers(userIds, positionId); }
catch (JeecgBootException e) {
  if (e.getMessage().contains("已存在该职位")) return Result.ok("部分用户已存在: " + e.getMessage());
  throw e;
}

When it happens

Trigger: POST to add-user-to-position with a userIds list containing one or more userIds that already exist in sys_user_position for the given positionId.

Common situations: Admin re-adds users already in the position; a previous add partially succeeded and was retried; duplicate userIds in the request; stale client-side state showing users as not-yet-added.
