iBatis学习五之修改实体对象

1、实现IStudentDAOImpl类中的updateStudentById()函数，代码如下：

@Override
public void updateStudentById(Student student) {
	// TODO Auto-generated method stub
	try {
		sqlMapClient.update("updateStudentById", student);
	} catch (SQLException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
}

2、Student.xml 文件中添加如下代码：

<!-- parameterClass="Student" 可改为 parameterClass="student"说明不区分大小写 -->
<update id="updateStudentById" parameterClass="Student"> update student set sname=#sname#,major=#major#,birthent=#birth#,score=#score# where sid=#sid#</update>

 

3、main()调用：

public static void main(String[] agr0) throws  Exception{
	IStudentDAO dao = new IStudentDAOImpl();
	Student stu = new Student();
	stu.setSid(7);
	stu.setSname("yyy");
	stu.setMajor("fffff");
	stu.setBirth(Date.valueOf("2013-10-14"));
	stu.setScore(94);
	dao.updateStudentById(stu);
}
