mapper 接口

package com.example.mapper;

import com.example.bean.Emplyee;
import org.apache.ibatis.annotations.Select;

import java.util.List;


public interface EmplyeeMapper {

    @Select("select * from emplyee\n" +
            "    where id = #{id}")
    Emplyee selectByPrimaryKey(Integer id);
    @Select(" select * from emplyee\n" +
            "    where logname = #{logname}\n" +
            "    and logpass=#{logpass}")
    Emplyee seleteEmpByNamePass(Emplyee u);


    @Select("select * from emplyee")
    List<Emplyee> selectAll();
}

service接口

import com.example.bean.Emplyee;


import java.util.List;


public interface UserService {

    /**
     * 查询所有人
     *
     * @return
     */
    List<Emplyee> selectAll();

}

实现类

@Service
public class UserServiceImpl implements UserService {

@Resource
private EmplyeeMapper emplyeeMapper;

@Override
public List<Emplyee> selectAllUser() {

    return emplyeeMapper.selectAllEmp();
}

}

controller

@Controller
@RequestMapping("*.do")
public class UserController {

    @Resource
    private UserService userService;

   

    @RequestMapping("/selectAll")
    public  String selectAll(HttpServletRequest request){
        List<Emplyee> users=userService.selectAllUser();
request.getSession().setAttribute("users",users);
 return "selectAll";
 }

    }

刚开始是无法直接建立jsp文件的,需要配置之后才能建立jsp
