1.在pom文件内添加plugin
<build>
<finalName>KenShrio</finalName>
<defaultGoal>compile</defaultGoal>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<!--指定配置文件位置-->
<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>
<dependencies>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.5</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
2.generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration

<!-- 配置 tableName,使用 Run As Maven build 生成 dao model 层 -->

<!-- 配置文件路径

<!--数据库驱动包路径 -->

<table tableName="T_USER"></table>
<table tableName="T_ROLE"></table>
<table tableName="T_USER_ROLE"></table>
<table tableName="T_PERMISSION"></table>
</context>
</generatorConfiguration>
3.用Maven命令mvn mybatis-generator:generate生成
