今天用MiinE制作一个java企业网站，结果产品录入时，总是无法输入，查看MiinE日志，反复多次仅无法找到原因。
后来看到一段java代码：
//private String inputUserName;
entry.setInputUserName((String)m.get("inputUserName"));
entry.setPrice((Float)m.get("price"));
意识到可能是数据库问题，进入miine产品表，修改price为Float,结果产品可成功保存了。
错误日志如下：

处理方法：
进入MiinE的mysql数据库，将产品表shop_product的price从varchar改为Float。
错误原因：数据库字段，导致MiinFramwork无法将数据记录转换为java实体类
MiinE是国内一款开源企业网站系统。
