开发常见问题

1.严重: IllegalArgumentException in class: com.viewhigh.xjcb.dise.queryAnal.deptDiseIncExp.vo.DeptDiseQnfx, setter method of property: total_cost

Caused by: java.lang.IllegalArgumentException: argument type mismatch

错误原因： 参数类型不匹配,在实体的set方法里参数类型为BigDecimal，数据在做SQL语句查询是经过Convert(decimal(18,6)，a)处理后为double类型数据
