</configuration> 3.导入mysqljdbc驱动和mybatis jar包文件 4.新建pojo即普通的java类Student 代码略过，一堆getset，注意定义构造方法 5.新建sqlSessionFactoryUtil类，注意该类中是静态方法，和hibernate相似 代码如下：
package com.java1234.util;
import java.io.InputStream;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
public class SqlSessionFactoryUtil {
private static SqlSessionFactory SqlSessionFatory;
public static SqlSessionFactory getSqlSessionFactory(){
if(SqlSessionFatory==null){
InputStream inputStream=null;
try{
inputStream=Resources.getResourceAsStream("mybatis-config.xml");
SqlSessionFatory=new SqlSessionFactoryBuilder().build(inputStream);
}catch(Exception e){
e.printStackTrace();
}
}
return SqlSessionFatory;
}
public static SqlSession openSession(){
return getSqlSessionFactory().openSession();
}
}
6.新建mapper接口和mapper映射文件 代码如下：
package com.java1234.mappers;
import com.java1234.model.Student;
public interface StudentMapper {
public int add(Student student);
}
=======
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
<mapper namespace="com.java1234.mappers.StudentMapper">
<insert id="add" parameterType="Student" >
insert into t_student values(null,#{name},#{age})
</insert>
< /mapper> 7.最后测试 代码如下
package com.java1234.service;
import org.apache.ibatis.session.SqlSession;
import com.java1234.mappers.StudentMapper;
import com.java1234.model.Student;
import com.java1234.util.SqlSessionFactoryUtil;
public class StudentTest {
public static void main(String[] args) {
// TODO Auto-generated method stub
SqlSession sqlSession=SqlSessionFactoryUtil.openSession();
StudentMapper studentMapper= sqlSession.getMapper(StudentMapper.class);
Student student=new Student("梁方明",30);
int result= studentMapper.add(student);
sqlSession.commit();
if(result>0){
System.out.println("添加成功");
}
}
}
8.这样就向mysql数据库添加了一条记录。
