问题描述：JUnit测试hibernate时候报错could not deserialize，检查实体映射类，实现了Serializable接口，但是有这样的
private String ordBy;
private String menuStatus;
private Serializable createDate;
private BigDecimal creater;
private Serializable updateDate;
private BigDecimal updater;

实体类使用hibernate Tool生成的，修改updateDate,createDate的类型后，能够成功运行了；

自动生成的时候，要多检查检查哦；

PS：今天程序中的数据库名称配错了，导致一直找不到某一个字段，郁闷了半天。。。
