mybatis原始碼解析第一課-mybatis原始碼匯入idea執行
阿新 • • 發佈：2018-12-15
從本篇部落格開始，進入mybatis的原始碼學習，本篇部落格主要是講解mybatis原始碼的下載，並將原始碼匯入到idea，可以用來除錯；
一、下載mybatis原始碼
版本：mybatis-3-mybatis-3.4.6.zip，下載地址：https://github.com/mybatis/mybatis-3
<parent> <groupId>org.mybatis</groupId> <artifactId>mybatis-parent</artifactId> <version>29</version> <relativePath /> </parent>
二、下載mybatis-parent
三、將以上兩個工程匯入到idea編譯除錯
匯入後效果如下：
<!-- 指定maven編譯的jdk版本 --> <profile> <id>jdk-1.8</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.8</jdk> </activation> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion> </properties> </profile>
3、實際在上編譯過程中還遇到了其它問題，這裡就不一一說明，反正最後就是對pom.xml檔案做了修改之後就可以了 mybatis的pom.xml檔案內容如下：
