初识MyBatis-Generator

Posted 2021-11-28 wicher-lsl

详细请见: http://www.mybatis.org/generator/quickstart.html

使用mybatis-generator-core-x.x.x.jar加上配置文件来生成

1. 建立配置文件D:\temp\test.xml  (详细配置见官网)

说明:connectionURL中jdbc:sqlserver://192.168.xx.xx:端口;databaseName=WicherTest

用的sqlserver, 192.168.xx.xx:端口表示sqlserver服务端所在的ip及侦听的端口

WicherTest为数据库名,记得 databaseName关键字与前面的分隔符是分号(; ),自己有次写错了,结果。。。

2. 下载mybatis-generator-core-1.3.6.jar包 (通过maven下载的,使用的版本为 1.3.6)

  路径为:    C:\Users\wicher\.m2\repository\org\mybatis\generator\mybatis-generator-core\1.3.6

maven的pom.xml添加了

<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.6</version>
</dependency>

3. 执行DOS命令

java -jar C:\Users\wicher\.m2\repository\org\mybatis\generator\mybatis-generator-core\1.3.6\mybatis-generator-core-1.3.6.jar -configfile D:\temp\test.xml -overwrite
生成的文件就在 D:\WorkTest\wicherspringmfcfirst\src\main\java下,要留意执行结果
