一、pom配置
<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>
<dependencies>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
</plugin>
二、在resources目錄下創建generatorConfig.xml文件
<?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>
<!-- 本地數據庫驅動程序jar包的全路徑 -->
<classPathEntry location="E:\WebChat\target\webchat\file\jar\mysql-connector-java-5.1.25.jar"/>
<context id="context" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="false"/>
<property name="suppressDate" value="true"/>
</commentGenerator>
<!-- 數據庫的相關配置 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/test"
userId="root"
password="123"/>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 實體類生成的位置 -->
<javaModelGenerator targetPackage="org.tuliu.landtransfer.model" targetProject="./src/main/java">
<property name="enableSubPackages" value="false"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- *Mapper.xml 文件的位置 -->
<sqlMapGenerator targetPackage="org.tuliu.landtransfer.mapper" targetProject="./src/main/java">
<property name="enableSubPackages" value="false"/>
</sqlMapGenerator>
<!-- Mapper 接口文件的位置 -->
<javaClientGenerator targetPackage="org.tuliu.landtransfer.mapper" targetProject="./src/main/java" type="XMLMAPPER">
<property name="enableSubPackages" value="false"/>
</javaClientGenerator>
<!-- 相關表的配置 -->
<table tableName="test01" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
enableUpdateByExample="false"/>
</context>
</generatorConfiguration>
主要配置幾點，基本的mysql的jar包，數據庫的連接配置，然后最主要的4個路徑，實體類，mapper接口，mapper的sql，及表名。
三、添加maven命令
working dictionry為項目的所在位置
配置上述步驟后，在右側的maven列表中會出現
運行generate命令即可自動生成代碼。
可能遇到的問題，如若出現
[ERROR] No plugin found for prefix 'mybatis-generator' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\yamat\.m2\repository), central (http://repo.maven.apache.org/maven2)] -> [Help 1]

出現這個問題可能是因為maven命令的工作目錄沒有寫對，如下
如我開始寫的是fencheng-v2，沒有jspxcms，而fencheng-v2只是個目錄，只有在jspxcms下面才有pom，src，resources等目錄。
若有不對歡迎指出。
