mybatis入門實戰之CRUD

最近因爲項目中用到了mybatis，經過本身的實踐，但願將學到的東西分享給初學者html

Mybatis官網：http://www.mybatis.org/mybatis-3/zh/index.htmljava

推薦書籍： 深刻淺出MyBatis技術原理與實戰.pdfmysql

但願讀者在學習mybatis以前，最好先把官網與相關書籍瀏覽一下，加深我的的理解。sql

下面進入實戰：數據庫

先看看工程目錄mybatis

本工程爲maven工程，所需的jar包都在pom.xml文件中配置了，建議讀者本地將maven配置文件換成阿里雲鏡像，jar包下載速度有明顯提高app

     maven阿里雲鏡像配置maven

<mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.

    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
