配置文件（configuration XML）中包含了对 MyBatis 系统的核心设置，包含获取数据库连接实例的数据源（DataSource）和 决定事务范围和控制方式的事务管理器（TransactionManager）。XML 配置文件的详细内容后面再探讨，这里先给出一个简单的示 例： <transactionManager type="JDBC"/> typeAliases 类型命名 typeHandlers 类型处理器 objectFactory 对象工厂 plugins 插件 environments 环境 environment 环境变量 transactionManager 事务管理器 dataSource 数据源 databaseIdProvider 数据库厂商标识 mappers 映射器 properties 这些属性都是可外部配置且可动态替换的，既可以在典型的

default = "default_environment _name"> <transactionManager type = "JDBC/MANAGED"/> elements. To configure the environment, we are provided with two sub tags namely transactionManager and dataSource. transactionManager tag MyBatis supports two transaction managers namely JDBC and MANAGED If practice − <transactionManager type = "JDBC"/>
