例

包结构

数据库

在这里插入图片描述

bean层

package com.hsp.bean;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import org.springframework.stereotype.Component;

@Data
@ToString
@AllArgsConstructor
@NoArgsConstructor
@Component
public class Student {
    private int id;
    private String Name;
}

dao层

实现类

package com.hsp.dao.impl;

import com.hsp.bean.Student;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.stereotype.Repository;

import javax.annotation.Resource;
import java.util.List;
@Repository
public class StudentDao implements com.hsp.dao.StudentDaoa {
    @Resource
    private SqlSessionTemplate sqlSessionTemplate;
    public List<Student> getAll(){
        return sqlSessionTemplate.selectList("com.hsp.dao.StudentDaoa.getAll");
    }
}

接口

package com.hsp.dao;

import com.hsp.bean.Student;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface StudentDaoa {

    public List<Student> getAll();
}

Service层

package com.hsp.service.impl;


import com.hsp.bean.Student;
import com.hsp.dao.StudentDaoa;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

@Service
public class StudentService {
    @Resource
    private StudentDaoa dao;
    public List<Student> getAll(){
        return dao.getAll();
    }
}

控制层

package com.hsp.controller;

import com.hsp.bean.Student;
import com.hsp.service.impl.StudentService;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;


import javax.annotation.Resource;
import java.util.List;
@org.springframework.stereotype.Controller
public class Controller {
    @Resource
    private StudentService studentService;

    @RequestMapping("/text")
    public String getAll(ModelMap map){

        List<Student> students = studentService.getAll();
        for (Student student : students) {
            System.out.println(student);
        }
        map.addAttribute("stu",students);
        return "show";
    }
}
