你在Students.java里面加上toString方法,里面加上你的Students的參數(shù)就ok了.

查詢學生的時候出現(xiàn)只有地址的情況，是因為query.list返回的對象是Object類型是，需要我們手動將它轉(zhuǎn)為Students類型，首先在StudentsDAO ?將queryAllStudents的返回值改為List<Object[]>，然后在test類中書寫以下代碼
StudentsDAO sdao = new StudentsDAOImpl();
List<Object[]> list = sdao.queryAllStudents();?
//轉(zhuǎn)換 ?
List<Students> prolist = new ArrayList<Students>(); ?
for(int i=0; i<list.size(); i++){ ?
Object[] obs=list.get(i); ?
Students student = new Students(); ?
student.setSid((String)obs[0]); ?
student.setSname((String)obs[1]); ?
student.setGender((String)obs[2]); ?
student.setBirthday((Date)obs[3]); ?
student.setAddress((String)obs[4]); ?
prolist.add(student); ?
}
for(int i = 0;i<prolist.size();i++){
System.out.println(prolist.get(i));
}

實體類中Suorce加個toString函數(shù)

沒有重寫toString函數(shù)，在你的實體類里加toString函數(shù)就行，返回值就是你想輸出的東西。
