int count =hrDeliverEmployContractService.selectCount(new EntityWrapper<HrDeliverEmployContractEntity>()
                .eq("pool_id",hrDeliverEmployContract.getPoolId()).andNew().lt("contract_start_date",hrDeliverEmployContract.getContractStartDate()).or().gt("contract_end_date",hrDeliverEmployContract.getContractEndDate())  );

对应的SQL

 
 SELECT COUNT(1)
 FROM hr_deliver_employ_contract
 WHERE (pool_id = 1) AND (contract_start_date < '2018-07-01 00:00:00.0' OR contract_end_date > '2018-10-31 00:00:00.0');
