特性的描述，那么你能做的最好的事情莫过于去研究它并把文档写出来。 该文档 xdoc 格式的源码文件可通过项目的 Git 代码库 来获取。Fork 该源码库，做出更新，然后提交一个 pull request 吧。 你将成为本文档的最佳作者，MyBatis 的用户定会过来查阅的。 当前的国际化版本 当前的国际化版本 MyBatis 的其他语言版本： English Español 日本語 한국어 SqlSession 里被请求的。尽管如此，映射器实例的最佳范围是方法范围。也就是说，映射器 实例应该在调用它们的方法中被请求，用过之后即可废弃。并不需要显式地关闭映射器实例，尽管在整个请求范围（request scope） 保持映射器实例也不会有什么问题，但是很快你会发现，像 SqlSession 一样，在这个范围上管理太多的资源的话会难于控制。所以要 PDFmyURL - the best online 制,你可以使用回滚选择来使它成为可能。 NOTE NOTE MyBatis-Spring and MyBatis-Guice provide declarative transaction handling.
