Mybatis工具类(MybatisUtil)

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 java.io.IOException;
import java.io.InputStream;

public class MybatisUtils {
    private static SqlSessionFactory sqlSessionFactory;

    static {
        String resource = "mybatis-config.xml";
        try {
            InputStream inputStream = Resources.getResourceAsStream(resource);
            sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static SqlSession getSqlSession(){
        return sqlSessionFactory.openSession();
    }
}

若想实现事务的自动提交，则getSqlSession()修改为以下实现

//获取SqlSession连接
public static SqlSession getSqlSession(){
	return getSqlSession(true); //事务自动提交
} 
public static SqlSession getSqlSession(boolean flag){
	return sqlSessionFactory.openSession(flag);
}
