第一步:pom.xml
<dependencies> <dependency> <groupId>com.macro.mall</groupId> <artifactId>mall-common</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <!-- MyBatis 生成器 --> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.3</version> </dependency> <!-- MyBatis--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> <!--Mysql数据库驱动--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.15</version> </dependency> </dependencies>
第二步:generatorConfig.xml
<?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> <properties resource="generator.properties"/> <context id="MySqlContext" targetRuntime="MyBatis3" defaultModelType="flat"> <property name="beginningDelimiter" value="`"/> <property name="endingDelimiter" value="`"/> <property name="javaFileEncoding" value="UTF-8"/> <!-- 为模型生成序列化方法--> <plugin type="org.mybatis.generator.plugins.SerializablePlugin"/> <!-- 为生成的Java模型创建一个toString方法 --> <plugin type="org.mybatis.generator.plugins.ToStringPlugin"/> <commentGenerator type="com.macro.mall.CommentGenerator"> <!-- 是否去除自动生成的注释 true:是 : false:否 --> <property name="suppressAllComments" value="true"/> <property name="suppressDate" value="true"/> <property name="addRemarkComments" value="true"/> </commentGenerator> <jdbcConnection driverClass="${jdbc.driverClass}" connectionURL="${jdbc.connectionURL}" userId="${jdbc.userId}" password="${jdbc.password}"> <!--解决mysql驱动升级到8.0后不生成指定数据库代码的问题--> <property name="nullCatalogMeansCurrent" value="true" /> </jdbcConnection> <javaModelGenerator targetPackage="com.macro.mall.model" targetProject="mall-mbg\src\main\java"/> <sqlMapGenerator targetPackage="com.macro.mall.mapper" targetProject="mall-mbg\src\main\resources"/> <javaClientGenerator type="XMLMAPPER" targetPackage="com.macro.mall.mapper" targetProject="mall-mbg\src\main\java"/> <!--生成全部表tableName设为%--> <table tableName="%"> <generatedKey column="id" sqlStatement="MySql" identity="true"/> </table> </context> </generatorConfiguration>
第三步:generator.properties
jdbc.driverClass=com.mysql.jdbc.Driver jdbc.connectionURL=jdbc:mysql://localhost:3306/mall?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai jdbc.userId=root jdbc.password=123456
第四步:Generator
