# 1、业务背景
### 功能诉求
单据头有一个字段：项目负责人。另外，单据上有一些敏感字段，这些字段只能让项目负责人以及项目负责人的领导才能看见，一般业务员是不能看到这些字段。
### 方案分析
目前标准产品中，字段权限方案的配置只能通过用户直接授权、通用角色授权配置，但是这些都只能指定用户或者角色对这些字段可见还是不可见，没有办法动态设置。

import kd.bos.bill.AbstractBillPlugIn;
import kd.bos.dataentity.entity.DynamicObject;
import kd.bos.servicehelper.user.UserServiceHelper;

public class BillFieldVisible extends AbstractBillPlugIn {
@Override
public void afterBindData(EventObject e) {
//get current user
Long userId = UserServiceHelper.getCurrentUserId();
//get chargerid from bill

Long chargerId = dynamicObject.getLong("id");
boolean isCurrentUserCharger = getProjectChargerList(userId, chargerId);
if (!isCurrentUserCharger)
handelField();
}

List<Long> userIds = new ArrayList<>(1);
userIds.add(projectCharger);
List<Map<String, Object>> userPositionList = UserServiceHelper.getPosition(userIds);
//traverse all the psotion and get the org supervisor
Set<Long> userSet = new HashSet<>();
userPositionList.forEach(stringObjectMap -> {
List<Map<String, Object>> dynamicObject1 = (List) stringObjectMap.get("entryentity");
DynamicObject dynamicObject2 = (DynamicObject) dynamicObject1.get(0).get("dpt");
Long orgId = dynamicObject2.getLong("id");
List<Long> userIds2 = UserServiceHelper.getManagersOfOrg(orgId);
userSet.addAll(userIds2);
});
//traversal supervisor list and judge if current user is in the list
for (Long aLong : userSet) {
if (aLong.longValue() == currentUser.longValue())
return true;
}
return false;
}
private enum Field {
field1,
field2,
field3,
}
}
