实体类映射数据库出现：异常：java.lang.IllegalArgumentException: argument type mismatch

异常：java.lang.IllegalArgumentException: argument type mismatch

[2017-11-25 16:39:58] [ERROR] [org.apache.commons.beanutils.PropertyUtils:1777] Method invocation failed.
查询数据库，做一个JavaBean的映射出现了下面的问题
SELECT pp.product_code as productCode,pp.product_name as productName,pp.product_standard as productStandard,pp.product_unit as productUnit,pp.shape_code as shapeCode,SUM(osr.op_sales_volume) as opSalesVolume ,pp.id as productId from op_sales_estimate as ose INNER JOIN op_sales_relation as osr ON ose.id = osr.op_sales_estimate_id inner JOIN pc_product as pp ON osr.op_product_id = pp.id where ose.op_audit_status > 0 and UNIX_TIMESTAMP(ose.op_market_start_date) >= UNIX_TIMESTAMP(‘2017-11-24 00:00:00’) and UNIX_TIMESTAMP(ose.op_market_end_date)<= UNIX_TIMESTAMP(‘2017-11-30 23:59:59’) GROUP BY pp.product_name

异常还提示了下面的

然后我将映射类，改成Object类，发现没问题，List集合中返回了5个对象

结果

然后我判定应该是映射的JavaBean和数据库返回的类型不匹配
