測試數(shù)據(jù)時代碼如下

GoddessDao?g=new?GoddessDao();
Goddess?g1=new?Goddess();
????????g1.setUser_name("小蘭");
????????g1.setAge(21);
????????g1.setSex(1);
????????g1.setBirthday(new?Date());//定義為今天，用util類型
????????g1.setEmail("xiaolan@123.com");
????????g1.setMobile("15071234567");
????????g1.setUpdate_user("ADMIN");//更新人
????????g1.setIsdel(1);//是否刪除，否
????????
????????g1.setId(4);
????????g.updateGoddess(g1);

最后報錯
