QueryWrapper查询失效

错误代码：

if (!CollectionUtils.isEmpty(warehouseIds)) {
            lambda.in(StockTransferEntity::getInWarehouseId, warehouseIds).or().in(StockTransferEntity::getOutWarehouseId, warehouseIds);
        }

打印sql：

SELECT * FROM dfs_stock_transfer 
WHERE (in_warehouse_id IN (375822,375825,375824,375823) 
            OR out_warehouse_id IN (375822,375825,375824,375823)AND out_warehouse_name = '34') 
ORDER BY create_time DESC LIMIT 20

错误结果：

 

 

 错误原因：

QueryWrapper.in()查询使后面的QueryWrapper查询条件失效:

lambda.eq(StockTransferEntity::getOutWarehouseName, outWarehouseName);

正确代码：

        if (!CollectionUtils.isEmpty(warehouseIds)) {
            List<Integer> finalWarehouseIds = warehouseIds;
            lambda.and(wrapper -> wrapper.in(StockTransferEntity::getInWarehouseId, finalWarehouseIds)
                    .or().in(StockTransferEntity::getOutWarehouseId, finalWarehouseIds));
        }

打印sql：

SELECT * FROM dfs_stock_transfer
WHERE ((in_warehouse_id IN (375822,375825,375824,375823) 
            OR out_warehouse_id IN (375822,375825,375824,375823)) AND out_warehouse_name = '34')
ORDER BY create_time DESC LIMIT 20

正确结果：
