MyBatis --generator

使用代码生成器的步骤以下：

1.建立生成数据的数据源，即数据库表；咱们须要对某一张表或者多张表生成xx.mapper、xx.mappering、xx.bean文件。以下是我在navicat中建立好的部分表。

2.在pom.xml中添加mybatis-generator-core

3.在pom.xml中添加链接mysql的驱动jar包

4.maven依赖包显示以下

5.建立配置文件generator.xml

6.备注

须要注意的有数据库驱动、数据库URL、用户名、密码、生成模型的包名和位置、生成映射文件的包名和位置、生成DAO的包名和位置以及最后须要生成的表名和对应的类名。

7.运行

须要经过CMD命令行方式来运行，首先能够先准备一个运行的脚本，这里使用的脚本是：java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

须要注意的是：mybatis-generator-core-1.3.2.jar为下载的对应版本的jar，generatorConfig.xml 为配置文件名，若是不为这个能够在这里进行修改。

启动cmd进入到“F:\soft\mybatis-generator-core-1.3.2\lib”这个目录下，如图：
