使用mybatis命令工具生成映射文件

###如何通过 mybatis自动生成xml,dao,bean

###准备工具

mybatis-generator-core-1.3.2 工具jar包

mysql-connector-java-5.1.40 数据库连接jar包

mybatis-generate-config xml配置文件

###mybatis-generate-config

<?xml version="1.0" encoding="UTF-8"?>

</context>
</generatorConfiguration>

####注意： 在配置里面写的java 和resourse 目录必须存在也可以自己命名 ,工具放置好了



####生成文件,进入命令行输入相应得命令

java -jar mybatis-generator-core-1.3.2.jar -configfile mybatis-generate-config.xml -overwrite
