1.添加mybatis-generator插件，打开pom.xml文件 在project节点下添加：
<build>
<plugins>
<!-- MyBatis代码生成 -->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<verbose>true</verbose>
<overwrite>true</overwrite>
<configurationFile>src_config/generatorConfig.xml</configurationFile>
</configuration>
</plugin>
</plugins>
<resources>
<!-- 配置多个资源文件夹 -->
<resource>
<directory>src_config</directory>
</resource>
</resources>
</build>
2.maven默认的资源文件是放在：src/main/resources下的，笔者习惯放在src_config下，所以上面使用了resources节点配置多个资源文件夹
3.添加generatorConfig.properties文件，内容如下：
#数据库驱动jar
drive.class.path=C:/Users/think/.m2/repository/mysql/mysql-connector-java/5.1.30/mysql-connector-java-5.1.30.jar #数据库连接参数
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/trip?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=root #包路径配置
model.package=com.trip.model
dao.package=com.trip.dao
xml.mapper.package=resources\mybatis\mappers
target.project=src/main/java
注意：mysql-connector-java-5.1.30.jar路径 使用/ ，key-value后面不要有多余的空格，否则会报找不到jdbc驱动。
4.添加generatorConfig.xml文件，内容如下：
<?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>
<!-- 配置文件路径 -->
<properties resource="generatorConfig.properties"/>
<!--数据库驱动包路径 -->
<classPathEntry location="${drive.class.path}"/> <context id="MySQLTables" targetRuntime="MyBatis3">
<!--关闭注释 -->
<commentGenerator>
<property name="suppressDate" value="true"/>
</commentGenerator> <!--数据库连接信息 -->
<jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}"
password="${jdbc.password}">
</jdbcConnection> <!--生成的model 包路径 -->
<javaModelGenerator targetPackage="${model.package}" targetProject="${target.project}">
<property name="enableSubPackages" value="ture"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator> <!--生成xml mapper文件 路径 -->
<sqlMapGenerator targetPackage="mybatis/mappers" targetProject="src_auth">
<property name="enableSubPackages" value="ture"/>
</sqlMapGenerator> <!-- 生成的Dao接口 的包路径 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="${dao.package}" targetProject="${target.project}">
<property name="enableSubPackages" value="ture"/>
</javaClientGenerator> <!--对应数据库表名 -->
<table tableName="auth_user"> </table>
</context>
</generatorConfiguration>
5.运行mybatis-generator插件
2.输入命令：mybatis-generator:generate
3.生成成功
