Salesforce 代码锁定记录

需要在“流程自动设置“中 选择在Apex 中启用记录锁定和解锁复选框

global class LockAndUnlock {
  //订单锁定
    WebService static void lock(Id OrderId){
      List orderList = [Select Id from MicroPowderOrder__c where Id = :OrderId];
      Approval.lock(orderList, false);
    }

    //订单解锁
    WebService static void unLock(Id OrderId){
      List orderList = [Select Id,OrderStatus__c from MicroPowderOrder__c where Id = :OrderId];
        for(MicroPowderOrder__c mpo : orderList){
            mpo.OrderStatus__c = '草稿';
        }
        update orderList;
      Approval.unlock(orderList, false);
    }
}
