如何使用mybatis 自动生成代码

回答（1）：

利用mybatis-generator自动生成代码
一、在pom.xml中添加plugin

org.mybatis.generator
mybatis-generator-maven-plugin
1.3.2

src/main/resources/mybatis-generator/generatorConfig.xml
true
true

Generate MyBatis Artifacts

generate

org.mybatis.generator
mybatis-generator-core
1.3.2

其中generatorConfig.xml的位置，自行调整。
二、generatorConfig.xml配置文件

PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

location="C:/Oracle/Middleware/wlserver_10.3/server/lib/ojdbc6.jar"/>

connectionURL="jdbc:oracle:thin:@172.20.16.***:1521:CARGO" userId="***"
password="***"/>

targetProject="D:/yangjm/Code/CTAS/JAVAEE/CTAS2CCSP/src/main/java">

targetProject="D:/yangjm/Code/CTAS/JAVAEE/CTAS2CCSP/src/main/java">

targetProject="D:/yangjm/Code/CTAS/JAVAEE/CTAS2CCSP/src/main/java" type="XMLMAPPER">

enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false">

几个要点：
a) 因为生成过程中需要连接db，所以第3行指定了驱动jar包的位置
b) 15-17行为连接字符串
c) 19-33行指定生成“entity实体类、mybatis映射xml文件、mapper接口”的具体位置
d) 40-46行为具体要生成的表，如果有多个表，复制这一段，改下表名即可
三、使用方式
mvn mybatis-generator:generate
如果是在intellij 环境，直接鼠标点击即可
