通用mapper批量新增
一、tk.mapper 4.0版本之前
tk.mybatis.mapper.common.MySqlMapper中没有添加@tk.mybatis.mapper.annotation.RegisterMapper 这个注解,需要将该类配置到mappers中:
修改后的通用接口扫描代码:
@Bean public MapperScannerConfigurer mapperScannerConfigurer(){ Properties properties=new Properties(); properties.put("mappers","tk.mybatis.mapper.common.Mapper,tk.mybatis.mapper.common.MySqlMapper"); MapperScannerConfigurer msc=new MapperScannerConfigurer(); msc.getMapperHelper().setProperties(properties); msc.setBasePackage(DataSourceConfig.PACKAGE); msc.setSqlSessionFactoryBeanName(DataSourceConfig.SESSION_FACTORY_BEAN_NAME); return msc; }
参考:https://www.cnblogs.com/yql1986/p/9459478.html
然后dao继承该接口就可以了:
public interface UserSystemMessageDao extends Mapper<UserSystemMessagePo>, MySqlMapper<UserSystemMessagePo> {
使用如下:
// 批量添加用户系统消息 userSystemMessageDao.insertList(addList);
一、tk.mapper 4.0版本之后
tk.mybatis.mapper.common.MySqlMapper中添加了@tk.mybatis.mapper.annotation.RegisterMapper,该注解会自动注入当前mapper,源码如下:

dao类直接继承MySqlMapper进行批量添加就可以,跟上面一样;
带着疑问去思考,然后串联,进而归纳总结,不断追问自己,进行自我辩证,像侦查嫌疑案件一样看待技术问题,漆黑的街道,你我一起寻找线索,你就是技术界大侦探福尔摩斯
