这样的映射器类（Mapper class）来说，还有另一招来处理。它们的映射的语句可以不需要用 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}") manually or automatically with PDFmyURL 也可以指定一个包名，MyBatis 会在包名下面搜索需要的 Java Bean，比如: <package name="domain.blog"/> 每一个在包 domain.blog 中的 Java Bean，在没有注解的情况下，会使用 Bean 的首字母小写的非限定类名来作为它的别名。 属性中也同时指定，则注解方式将被忽略。 最后，可以让 MyBatis 为你查找类型处理器： <package name="org.mybatis.example"/> 注意在使用自动检索（autodiscovery）功能的时候，只能通过注解方式来指定 JDBC 的类型。
