使用MyBatis-Generator自動(dòng)生成映射文件
生成的方式一共有三種
1、使用cmd命令方式生成。
首先在generator.xml中指定數(shù)據(jù)庫(kù)驅(qū)動(dòng)包位置，然后在mybatis-generator-core-1.3.1包下創(chuàng)建一個(gè)src文件夾（否則生成的文件沒(méi)地方放）
生產(chǎn)的Mapper.xml文件與domain類放在一個(gè)報(bào)下面（否則無(wú)法映射）
E:/>java -jar E:/mybatis-generator-core-1.3.1/lib/mybatis-generator-core-1.3.1.jar -configfile E:/mybatis-generator-core-1.3.1/generator.xml -overwritegenerator.xml

Command line:
mybatis-generator:generateeclipse下
pom.xml配置同上
Goals
mybatis-generator:generate注意：maven方式啟動(dòng)的話，上面geterator.properties里的project與resource 需要去掉項(xiàng)目名稱。
generatorConfig.xml里面targetRuntime與自定義注釋的java文件配置的是修改完源碼導(dǎo)入到項(xiàng)目中jar的路徑。
3、如果開(kāi)發(fā)工具為eclipse，可以安裝Generator的插件，然后生成generatorConfig.xml進(jìn)行修改配置。
最后通過(guò)右鍵就可以運(yùn)行。
