添加配置文件

在项目resource目录下创建mybatis-generator文件夹

在文件夹下创建generatorConfig.xml，配置需要生成代码的数据表

<?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="mybatis-generator/generator.properties"/> <!-- 连接数据库jar包的路径--> <!--<classPathEntry location="d:/java/JavaTools/mysql-connector-java-5.1.48/mysql-connector-java-5.1.48-bin.jar"/>--> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <!-- 是否去除自动生成的注释 true：是 ： false:否 --> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--数据库连接参数 --> <jdbcConnection driverClass="${driverClassName}" connectionURL="${url}" userId="${username}" password="${password}"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!-- 实体类的包名和存放路径 --> <javaModelGenerator targetPackage="com.shop.order.bean" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!-- 生成映射文件*.xml的位置--> <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!-- 生成DAO的包名和位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.shop.order.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!-- tableName：数据库中的表名或视图名；domainObjectName：生成的实体类的类名--> <table tableName="book" domainObjectName="Book" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"/> <!-- 可以添加多个需要生产代码的实体--> <!-- <table tableName="xxx" domainObjectName="xxx" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"/> ... <table tableName="xxx" domainObjectName="xxx" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"/> --> </context></generatorConfiguration>

在文件夹下创建generator.properties配置文件

driverClassName=com.mysql.jdbc.Driverurl=jdbc:mysql://localhost:3306/store?useUnicode=true&characterEncoding=UTF-8&relaxAutoCommit=true&zeroDateTimeBehavior=convertToNullusername=rootpassword=root

配置Maven

pom.xml中引入依赖

<build> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.5</version> <configuration> <configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile> <verbose>true</verbose> <overwrite>true</overwrite> </configuration> <executions> <execution> <id>Generate MyBatis Artifacts</id> <goals> <goal>generate</goal> </goals> </execution> </executions> <dependencies> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency> </dependencies> </plugin> </plugins> </build>

执行Maven插件

双击运行mybatis-generator:generate

控制台输出结果，生产mapper和bean文件
