package com.ycz.mapper;

import com.ycz.entity.Emp;

import org.apache.ibatis.annotations.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;

import java.util.List;

/**
 * (Emp)表数据库访问层
 *
 * @author makejava
 * @since 2021-12-13 15:57:41
 */
@Mapper
public interface EmpMapper extends tk.mybatis.mapper.common.Mapper<Emp>, MySqlMapper<Emp> {

    Emp queryById(Integer id);
}

server层

    @Override
    public Object queryAll() {
        return empMapper.selectAll();
    }

controller层

    @RequestMapping("/all")
    @ResponseBody
    public Object getAll(){
        return empService.queryAll();
    }
