求助，spring与ibatis整合问题

Question

Answer 1

student的model如下：
public class Ss_student {
String studentno;
String name;
String sex;
String classno;
String password;

public String getStudentno() {
return studentno;
}
public void setStudentno(String studentno) {
this.studentno = studentno;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getClassno() {
return classno;
}
public void setClassno(String classno) {
this.classno = classno;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}dao的实现类如下
package com.daiq.dao;import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import org.springframework.stereotype.Component;import com.daiq.dto.Ss_student;@Component
public class Student_daoImpl extends SqlMapClientDaoSupport implements Student_dao{ public boolean insertStudent(Ss_student student) {
getSqlMapClientTemplate().insert("getStudentPassword.insertStudent",student);
System.out.println("insert success");
return true;
}}service如下：
@Component("Student_service")
public class Student_service {

@Resource
Student_daoImpl student_daoImpl;

public void printStudent(){
System.out.println("print success");
}

public boolean insertStudent(Ss_student student){
return student_daoImpl.insertStudent(student);
}
}
测试类如下：
public class test { /**
 * @param args
 */
public static void main(String[] args) {
Ss_student student = new Ss_student();
student.setStudentno("004");
student.setName("xiaoming");
student.setSex("1");
student.setClassno("999");
student.setPassword("12345");

ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"config/beans.xml"});
Student_service student_service = (Student_service)context.getBean("Student_service");
student_service.insertStudent(student);

}}

Answer 2

修改成这样就行了 
@Component ("Student_dao")
public class Student_daoImpl extends SqlMapClientDaoSupport implements Student_dao{
 
    public boolean insertStudent(Ss_student student) {
        getSqlMapClientTemplate().insert("getStudentPassword.insertStudent",student);
        System.out.println("insert success");
        return true;
    }
 
}
@Component("Student_service")
public class Student_service {
     
    @Resource ("Student_dao")
    Student_daoImpl student_daoImpl;
     
    public void printStudent(){
        System.out.println("print success");
    }
     
    public boolean insertStudent(Ss_student student){
        return student_daoImpl.insertStudent(student);
    }
}
