# 第一步：引入依赖 #

同样要注意位置，不要写到它自己生成的那个插件标签中，自己重新写一个

<plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.3.2</version>
            <configuration>
              <verbose>true</verbose>
              <overwrite>false</overwrite>
            </configuration>
            <dependencies>
              <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.21</version>
              </dependency>
            </dependencies>
          </plugin>

# 第二步：引入配置文件并修改相关参数（generatorConfig.xml） #

这里有几个要修改的地方：

1.domain生成的地址（包）

2.mapper接口生成的地址

3.mapper.xml生成的地址

4.要生成哪一个表（最后指定的，名字要和数据库的表明一致）

5.数据库的连接信息：用户名：密码：数据库名

    		<sqlMapGenerator targetPackage="com.ctbu.mapper"
    						 targetProject="src/main/java">
    			
    			<property name="enableSubPackages" value="true" />
    		</sqlMapGenerator>
    
    		
    		<javaClientGenerator targetPackage="com.ctbu.mapper"
    							 type="XMLMAPPER" targetProject="src/main/java">
    			<property name="enableSubPackages" value="true" />
    		</javaClientGenerator>
    
    		<table tableName="customer"></table>
    
    	</context>
    </generatorConfiguration>

# 第三步:创建好对应的包名并执行插件生成相应的代码 #
