mybatis官网上下载generator需要jar包 https://github.com/mybatis/generator/releases
数据库的驱动以及配置generatorConfig.xml都准备好就可以了,操作非常简单
目录如下:
generatorConfig.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!-- 数据库驱动包位置 -->
<classPathEntry location="/soft/java/workspace/permission/generator/mysql-connector-java-5.1.34.jar" /> <!-- 1 -->
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 数据库链接URL、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1:3306/authorization?characterEncoding=utf8" userId="root" password="*****"> <!-- 2 -->
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- 生成模型的包名和位置 --> <!-- 3 -->
<javaModelGenerator targetPackage="cn.qblank.model" targetProject="/soft/java/workspace/permission/generator/src">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- 生成的映射文件包名和位置 --> <!-- 4 -->
<sqlMapGenerator targetPackage="cn.qblank.mapper" targetProject="/soft/java/workspace/permission/generator/src">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- 生成DAO的包名和位置 --> <!-- 5 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="cn.qblank.dao" targetProject="/soft/java/workspace/permission/generator/src">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- 要生成那些表(更改tableName和domainObjectName就可以) --><!-- 6 -->
<table tableName="sys_user" domainObjectName="SysUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="sys_dept" domainObjectName="SysDept" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="sys_acl" domainObjectName="SysAcl" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="sys_acl_module" domainObjectName="SysAclModule" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="sys_role" domainObjectName="SysRole" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="sys_role_acl" domainObjectName="SysRoleAcl" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="sys_role_user" domainObjectName="SysRoleUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="sys_log" domainObjectName="SysLog" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
</context>
</generatorConfiguration>
修改配置，用户名，密码，数据库名和表名
打开终端输入命令:
java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite
就能生成对应所以文件了
这样逆向工程大大减少了开发时间和提高了开发效率,简单直接
