数据库：

create table STUDENT(  STUID    NUMBER(9) not null,  SNAME    VARCHAR2(50) not null,  SEX      VARCHAR2(4),  ADDRESS  VARCHAR2(50),  BIRTHDAY DATE)

 目录结构：

Student类：

package com.bean;import java.io.Serializable;import java.util.Date;import oracle.jdbc.driver.OracleDriver;public class Student implements Serializable {		private Integer stuid;	private String sname;	private String sex;	private String address;	private Date birthday;	public Student() {		super();		// TODO Auto-generated constructor stub	}	public Student(Integer stuid, String sname, String sex, String address,			Date birthday) {		super();		this.stuid = stuid;		this.sname = sname;		this.sex = sex;		this.address = address;		this.birthday = birthday;	}	public Student(String sname, String sex, String address, Date birthday) {		super();		this.sname = sname;		this.sex = sex;		this.address = address;		this.birthday = birthday;	}	//set和get就不写了 		}

 IStudentMapper接口

package com.mapper;import com.bean.*;import java.util.*;public interface IStudentMapper {	public boolean save(Student st);	public boolean update(Student st);	public boolean delById(Integer sid);	public Student findById(Integer sid);	public List
     
       findAll();}
     

 StudentMapper.xml：

     
     	
      	
      	    
       	    
        		    
        		    
        		    
        		
      	
      
       		insert into student values(seqstu.nextval,#{sname},#{sex},#{address},#{birthday})	
      		
      
       		update student set sname=#{sname},sex=#{sex},address=#{address},birthday=#{birthday} where stuid=#{stuid}	
      		
      
       		delete from  student where stuid=#{sid}	
           
      		select * from student where stuid=#{sid} 	 
      
     

 TastAdd类：

package com.test;import com.bean.*;import java.io.*;import java.util.*;import org.apache.ibatis.io.Resources;import org.apache.ibatis.session.SqlSession;import org.apache.ibatis.session.SqlSessionFactory;import org.apache.ibatis.session.SqlSessionFactoryBuilder;import com.mapper.*;public class TastAdd {	/**	 * @param args	 */	public static void main(String[] args) {		try {			//获取资源文件的流			InputStream in=Resources.getResourceAsStream("mybatis-config.xml");						//获取SqlSessionFactory			SqlSessionFactory sqlSessionFactory=new SqlSessionFactoryBuilder().build(in);						//获取sqlSession			SqlSession session=sqlSessionFactory.openSession();						IStudentMapper dao=session.getMapper(IStudentMapper.class);						Student st=new Student("巨林", "男", "changshan", new Date());						boolean flag= dao.save(st);			if(flag){				System.out.println("保存成功！");				session.commit();			}else{				System.out.println("失败！");							}			session.close();					} catch (IOException e) {			// TODO Auto-generated catch block			e.printStackTrace();		}			}}

 mybatis-config.xml：

 然后运行就出错了。。。。

望有大神给出有效建议！！
