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
