项目报表 ## 从 XML 中构建 SqlSessionFactory  每个基于 MyBatis 的应用都是以一个 SqlSessionFactory 的实例为中心的。SqlSessionFactory 的实例可以通过 SqlSessionFactoryBuilder 获得。而 SqlSessionFactoryBuilder 则可以从 XML 配置文件或一个预先定制的 Configuration 的实例构建出 SqlSessionFactory 的实例。 从 XML 文件中构建 SqlSessionFactory 的实例非常简单，建议使用类路径下的资源文件进行配置。但是也可以使用任意的输入流 (InputStream) 实例，包括字符串形式的文件路径或者 file:// ybatis-config.xml"; InputStream inputStream = Resources.getResourceAsStream(resource); sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream); XML 配置文件（configuration XML）中包含了对 MyBatis

的运行环境等信息。mapper.xml 文件即 sql 映射文件，文件中配置了操作数据库的 sql 语句。此文件需要在 SqlMapConfig.xml 中加载。 2、通过 mybatis 环境等配置信息构造 SqlSessionFactory 即会话工厂 3、由会话工厂创建 sqlSession 即会话，操作数据库需要通过 sqlSession 进行。 4、mybatis 底层自定义了 Executor 执行器接口操作数据库，Executor ###### 1.6.7.1.3 测试程序： public class Mybatis_first { //会话工厂 private SqlSessionFactory sqlSessionFactory; @Before public void createSqlSessionFactory() throws IOException { // 配置文件 getResourceAsStream(resource); // 使用SqlSessionFactoryBuilder从xml配置文件中创建 SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder() .build(inputStream); } // 根据 id 查询用户信息
