mybatis的辅助类

 package org.ssi.util;

 import java.io.InputStream;

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

 public class MyBatisUtil {
         /**
           * 获取SqlSessionFactory
           * @return SqlSessionFactory
           */
         public static SqlSessionFactory getSqlSessionFactory() {
              String resource = "conf.xml";
              InputStream is = MyBatisUtil.class.getClassLoader().getResourceAsStream(resource);
              SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(is);
              return factory;
          }

          /**
           * 获取SqlSession
           * @return SqlSession
           */
          public static SqlSession getSqlSession() {
              return getSqlSessionFactory().openSession();
          }

          /**
           * 获取SqlSession
           * @param isAutoCommit
           *         true 表示创建的SqlSession对象在执行完SQL之后会自动提交事务
           *         false 表示创建的SqlSession对象在执行完SQL之后不会自动提交事务，这时就需要我们手动调用sqlSession.commit()提交事务
           * @return SqlSession
           */
         public static SqlSession getSqlSession(boolean isAutoCommit) {
              return getSqlSessionFactory().openSession(isAutoCommit);
          }
 }

有了这个辅助类，获取sqlsession来进行数据的增删改查就不容自己再一遍一遍的写了
