语句可以不需要用 XML 来做，取而 代之的是可以使用 Java 注解。比如，上面的 XML 示例可被替换如下： package org.mybatis.example; public interface BlogMapper { @Select("SELECT * FROM blog WHERE id = #{id}") Blog selectBlog(int id); } 模块会使用自带的管理器来覆盖前面的配置。 这两种事务管理器类型都不需要任何属性。它们不过是类型别名，换句话说，你可以使用 TransactionFactory 接口的实现类的完全限 定名或类型别名代替它们。 public interface TransactionFactory { void setProperties(Properties props); Transaction newTransaction(Connection } 任何在 XML 中配置的属性在实例化之后将会被传递给 setProperties() 方法。你也需要创建一个 Transaction 接口的实现类，这个接 口也很简单： public interface Transaction { Connection getConnection() throws SQLException; void commit() throws SQLException;
