依赖
<!-- mybatis-generator自动生成代码 -->
<dependency>
<groupId>org.mybatis.generator</groupId>

插件

在resources文件下创建generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<!-- 数据库驱动包位置 -->
<!-- 由于在pom.xml中加入插件时已经配置数据库驱动包,所以此处不必配置了-->
<!-- <classPathEntry
location="/Users/yehaixiao/Maven/mysql/mysql-connector-java/5.1.30/mysql-connector-java.jar"/> -->
<context id="my" targetRuntime="MyBatis3">

<property name="suppressAllComments" value="true" />

<!-- mysql数据库连接 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://127.0.0.1:3306/xx" userId="root"
password="123456" />
<!-- 生成model实体类文件位置 -->
<javaModelGenerator
targetPackage="com.xx.xx.entity"
targetProject="src/main/java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- 生成mapper.xml配置文件位置 -->
<sqlMapGenerator
targetPackage="mapper"
targetProject="src/main/resources">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- 生成mapper接口文件位置 -->
<javaClientGenerator
targetPackage="com.xx.xx.mapper"
targetProject="src/main/java"
type="XMLMAPPER">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- 需要生成的实体类对应的表名,多个实体类复制多份该配置即可 -->
<table tableName="数据库的表名" domainObjectName="创建类的名字"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false">
