mybatis的操作是对于dao层接口对应mapper里的同名xml，接口中的方法名对应xml里的同名select/update/insert/delete标签的id值，方法参数对应的是parameterType/parameterMap，方法的返回值对应的是resultType/resultMap。

对于mybatis的批量导入，当dao层接口的方法参数中使用@Param(value="insertOtherList")注解时,会将foreach标签的collection默认的值list修改为insertOtherList，此时在xml中处理时的写法是

dao层代码

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.baomidou.mybatisplus.service.impl.ServiceImpl;
import com.nssolsh.boot.modular.system.dao.ExeclAndDBBodyMapper;
import com.nssolsh.boot.modular.system.model.PSiDocBody;
import com.nssolsh.boot.modular.system.service.ExeclAndDBBodyService;

@Service
public class ExeclAndDBBodyServiceImpl  extends ServiceImpl<ExeclAndDBBodyMapper, PSiDocBody> implements ExeclAndDBBodyService {

	@Resource
	ExeclAndDBBodyMapper eam;
	
	@Override
	public int insertOtherBody(List<PSiDocBody> insertOtherList) {
		int flag = eam.insertOtherBody(insertOtherList);
		return flag;
	}
	
	
	/*@Override
	public void insertExeclBody(List<PSiDocBody> allDataList) {
		// TODO Auto-generated method stub
		
	}*/

}

对应的xml
