1 在resources文件夹下创建generatorConfig.xml文件来做相关配置
<?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>
<!--本机数据库驱动jar包存放目录-->
<classPathEntry location="E:\maven\repository\mysql\mysql-connector-java\5.1.46\mysql-connector-java-5.1.46.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--数据库驱动,数据库地址及表名,账号,密码-->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="12345">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!--生成Model类的包名及存放位置-->
<javaModelGenerator targetPackage="com.fengyuntec.domain" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!--生成映射文件的包名及存放位置-->
<sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!--生成Dao类的包名及存放位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.fengyuntec.dao" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!--生成对应表及类名,domainObjectName是设置实体类的名字的-->
<table tableName="user" domainObjectName="User" enableCountByExample="true" enableUpdateByExample="true" enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="true"></table>
</context>
</generatorConfiguration>
2 在pom.xml中添加相应的依赖和插件
依赖:
<!--mybatis-generator核心包-->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.2</version>
</dependency> 插件:
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<!--配置文件的位置-->
<configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
<executions>
<execution>
<id>Generate MyBatis Artifacts</id>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
</plugin>
3 如果在ecplise中使用,则右击工程,maven build,添加命令mybatis-generator:generate,代码生成完毕!
如果在idea中 如下图:
运行此命令即可。
