Maven使用Mybatis Generator插件生成Mapper接口 xml和实体

pom.xml

添加插件

<!-- 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>
<!-- 默认src/main/resources下 -->
<configurationFile>src/main/resources/mybatis-generator/generatorConfig.xml</configurationFile>
</configuration>
<!--插件添加依赖驱动，generatorConfig.xml无需配置classPathEntry-->
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.26</version>
</dependency>
</dependencies>
</plugin>

配置了mysql的驱动的依赖，无需配置generatorConfig.xml里的classPathEntry

jdbc.properties

数据库配置

validationQuery=SELECT 1
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/db_test?useUnicode=true&characterEncoding=utf-8
jdbc.username=kuaizihui_test
jdbc.password=kuaizihui123

generatorConfig.xml

在src/main/resources/mybatis-generator下创建

<?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>
<!-- 数据库配置文件路径 -->
<properties resource="conf/jdbc.properties" />

<!--数据库驱动包路径，mysql-connector-java-5.1.34.jar所在路径 -->  <!-- 如果pom插件里主动依赖了驱动，无需手动指定classPathEntry-->
<!-- 	<classPathEntry
location="C:/Users/lw/.m2/repository/mysql/mysql-connector-java/5.1.34/mysql-connector-java-5.1.34.jar" /> -->

<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="s.s.m.domain"
targetProject="src/main/java">
<property name="enableSubPackages" value="ture" />
<property name="trimStrings" value="true" />
</javaModelGenerator>

<!--生成xml mapper文件 路径 -->
<sqlMapGenerator targetPackage="s.s.m.dao"
targetProject="src/main/java">
<property name="enableSubPackages" value="ture" />
</sqlMapGenerator>

<!-- 生成的Dao接口 的包路径 -->
<javaClientGenerator type="XMLMAPPER"
targetPackage="s.s.m.dao" targetProject="src/main/java">
<property name="enableSubPackages" value="ture" />
</javaClientGenerator>

<!--对应数据库表名 ，指定生成的方法-->
<table schema="db_test" tableName="goods_back"
domainObjectName="GoodsBack" enableSelectByPrimaryKey="true"
enableInsert="true" enableUpdateByPrimaryKey="true"
enableDeleteByPrimaryKey="true" enableCountByExample="false"
enableUpdateByExample="false" enableDeleteByExample="false"
enableSelectByExample="false" selectByExampleQueryId="false">

</table>
</context>
</generatorConfiguration>

配置好以上之后，cmd切换到项目目录,运行maven命令：mvn mybatis-generator:generate

运行成功，就会生成了Mapper 接口和xml,还有model.
