下载jar包后
增加配置文件generatorConfig.xml：

无需其他关联配置

启动：

mybatis分页：

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
    @Override
    public PageInfo<DictBuildingWithBLOBs> getBuildingByPage(BuildingQueryDto queryDto) {
        PageHelper.startPage(queryDto.getPageNo(),queryDto.getPageSize());
        return new PageInfo(dictBuildingMapper.queryBuilding());
    }

			<groupId>com.github.pagehelper</groupId>
			<artifactId>pagehelper-spring-boot-starter</artifactId>
			<version>1.1.2</version>
		</dependency>
