01_4_插入一个实体对象

1. 配置映射配置

<insert id="insertStudent" parameterClass="Student">

  insert into Student(sid, name, major, birth, score) values(#sid#, #name#, #major#, #birth#, #score#)

  </insert>

2. 实现方法类

public void addStudent(Student student) {

try {

sqlMapClient.insert("insertStudent", student);

} catch (SQLException e) {

e.printStackTrace();

}

}

3. 调试及其结果

public static void main(String[] args) {

IStudentDAO dao = new IStudentDAOImpl();

Student student = new Student();

student.setSid(6);

student.setName("fengge");

student.setScore(100);

dao.addStudent(student);

for(Student stu : dao.queryAllStudent()) {

System.out.println(stu);

}

}
