test.java

package test;  

import java.io.Reader;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;


/** 
 * myBatis数据库连接测试 
 */  
public class test {  

    public static void main(String[] args) throws Exception {  
        //使用MyBatis提供的Resources类加载mybatis的配置文件（它也加载关联的映射文件）
        Reader reader = Resources.getResourceAsReader("poseidon.xml");  
        //构建sqlSession的工厂
        SqlSessionFactoryBuilder ssfBuilder = new SqlSessionFactoryBuilder();  
        SqlSessionFactory sqlSessionFactory = ssfBuilder.build(reader); 
        //创建能执行映射文件中sql的sqlSession
        SqlSession sqlSession = sqlSessionFactory.openSession();  
        //查询语句
        int count = sqlSession.selectOne("com.kyl.oracle.selectEmpCount");
        System.out.println("count:" + count);  
        sqlSession.close();  
    }  
} 

运行test文件里的main方法，可检验结果
