maven自动生成mapper和实体类

maven自动生成mapper和实体类

pom.xml文件添加以下配置

<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
		</plugin>
		
		<plugin>
		
			<!-- 自动生成dao vo mapper文件 -->
			<groupId>org.mybatis.generator</groupId>
               <artifactId>mybatis-generator-maven-plugin</artifactId>
               <version>1.3.5</version>
               <configuration>
                   <!--允许移动生成的文件 -->
                   <verbose>true</verbose>
                   <!--允许覆盖生成的文件 -->
                   <overwrite>true</overwrite>
               </configuration>
               
		</plugin>
	</plugins>
</build>

配置generatorConfig.xml文件

generatorConfig.xml文件放在resouces目录下
