更新時(shí)間：2022年07月25日 14:13:27 作者：沉河不浮

這篇文章主要為大家詳細(xì)介紹了springboot實(shí)現(xiàn)學(xué)生管理系統(tǒng)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了SpringBoot實(shí)現(xiàn)學(xué)生管理系統(tǒng)，供大家參考，具體內(nèi)容如下

一、創(chuàng)建springboot項(xiàng)目

點(diǎn)擊下一步，再點(diǎn)擊完成

修改pom.xml如下

修改resources目錄下的application.yml，代碼如下

spring:
? thymeleaf:
? ? prefix: classpath:/templates/
? ? suffix: .html
? mvc:
? ? view:
? ? ? static-path-pattern: /static/**
? datasource:
? ? url: jdbc:mysql://localhost:3306/springboot?useSSL=false&serverTimezone=UTC
? ? username: root
? ? password: 3fa4d180
? ? driver-class-name: com.mysql.cj.jdbc.Driver
mybatis:
? mapper-locations: classpath:mapper/*.xml

我們在我們創(chuàng)建的目錄下，創(chuàng)建pojo軟件包，在該包下創(chuàng)建Student.java

public class Student {
? ? private Integer id;
? ? private String name;
? ? private String grade;
? ? private String major;
? ? public Integer getId() {
? ? ? ? return id;
? ? }
? ? public void setId(Integer id) {
? ? ? ? this.id = id;
? ? }
? ? public String getName() {
? ? ? ? return name;
? ? }
? ? public void setName(String name) {
? ? ? ? this.name = name;
? ? }
? ? public String getGrade() {
? ? ? ? return grade;
? ? }
? ? public void setGrade(String grade) {
? ? ? ? this.grade = grade;
? ? }
? ? public String getMajor() {
? ? ? ? return major;
? ? }
? ? public void setMajor(String major) {
? ? ? ? this.major = major;
? ? }
? ? @Override
? ? public String toString(){
? ? ? ? return "Student{id="+id+",name="+name+
? ? ? ? ? ? ? ? ",grade="+grade+",major="+major+
? ? ? ? ? ? ? ? "}";
? ? }
}

我們在創(chuàng)建一個(gè)mapper軟件包，創(chuàng)建StudentMapper接口

@Mapper
public interface StudentMapper {
? ? List<Student>listStudent();
? ? List<Student>queryStudentByValue(String value);
? ? int saveStudent(Student student);
? ? int deleteStudent(Integer id);
? ? int updateStudent(Student student);
}

創(chuàng)建一個(gè)service軟件包，創(chuàng)建StudentService

@Service
public class StudentService {
? ? @Autowired
? ? private StudentMapper studentMapper;
? ? public List<Student>listStudent(){
? ? ? ? return studentMapper.listStudent();
? ? }
? ? public List<Student>queryStudentByValue(String value){
? ? ? ? return studentMapper.queryStudentByValue(value);
? ? }
? ? public int saveStudent(Student student){
? ? ? ? return studentMapper.saveStudent(student);
? ? }
? ? public int deleteStudent(Integer id){
? ? ? ? return studentMapper.deleteStudent(id);
? ? }
? ? public int updateStudent(Student student){
? ? ? ? return studentMapper.updateStudent(student);
? ? }
}

創(chuàng)建一個(gè)controller軟件包，創(chuàng)建StudentController

@RestController
@RequestMapping("/student")
public class StudentController {
? ? @Autowired
? ? private StudentService studentService;
? ? @RequestMapping("/listStudent")
? ? public ModelAndView listStudent(){
? ? ? ? List<Student>studentList=studentService.listStudent();
? ? ? ? ModelAndView modelAndView=new ModelAndView();
? ? ? ? modelAndView.addObject("studentList",studentList);
? ? ? ? modelAndView.setViewName("/listStudent");
? ? ? ? return modelAndView;
? ? }
? ? @RequestMapping("/queryStudentByValue")
? ? public ModelAndView queryStudentByValue(String value){
? ? ? ? List<Student>studentList=studentService.queryStudentByValue(value);
? ? ? ? ModelAndView modelAndView=new ModelAndView();
? ? ? ? modelAndView.addObject("studentList",studentList);
? ? ? ? modelAndView.setViewName("/listStudent");
? ? ? ? return modelAndView;
? ? }
? ? @RequestMapping("/saveStudent")
? ? public ModelAndView saveStudent(Student student){
? ? ? ? ModelAndView modelAndView=new ModelAndView();
? ? ? ? studentService.saveStudent(student);
? ? ? ? modelAndView.setViewName("forward:/student/listStudent");
? ? ? ? return modelAndView;
? ? }
? ? @RequestMapping("/updateStudent")
? ? public ModelAndView updateStudent(Student student){
? ? ? ? ModelAndView modelAndView=new ModelAndView();
? ? ? ? studentService.updateStudent(student);
? ? ? ? modelAndView.setViewName("forward:/student/listStudent");
? ? ? ? return modelAndView;
? ? }
? ? @RequestMapping("/deleteStudent")
? ? public ModelAndView deleteStudent(Integer id){
? ? ? ? ModelAndView modelAndView=new ModelAndView();
? ? ? ? studentService.deleteStudent(id);
? ? ? ? modelAndView.setViewName("forward:/student/listStudent");
? ? ? ? return modelAndView;
? ? }
}

在resources目錄下，創(chuàng)建mapper目錄，在該目錄下，放入我們的StudentMapper.xml配置

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
? ? ? ? PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
? ? ? ? "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.young.springboot04.mapper.StudentMapper">
? ? <select id="listStudent" resultType="com.young.springboot04.pojo.Student">
? ? ? ? select * from student
? ? </select>
? ? <select id="queryStudentByValue" parameterType="string" resultType="com.young.springboot04.pojo.Student">
? ? ? ? select * from student
? ? ? ? where id like '%${value}%' or name like '%${value}%' or grade like '%${value}%'
? ? ? ? or major like '%${value}%'
? ? </select>
? ? <insert id="saveStudent" parameterType="com.young.springboot04.pojo.Student">
? ? ? ? insert into student
? ? ? ? values(#{id},#{name},#{grade},#{major})
? ? </insert>
? ? <delete id="deleteStudent" parameterType="int">
? ? ? ? delete from student
? ? ? ? where id=#{id}
? ? </delete>
? ? <update id="updateStudent" parameterType="com.young.springboot04.pojo.Student">
? ? ? ? update student
? ? ? ? set name=#{name},grade=#{grade},major=#{major}
? ? ? ? where id=#{id}
? ? </update>
</mapper>

在我們的static目錄下，放入我們需要的css目錄，我這里用的是pio框架的css目錄
接著我們在templates目錄下創(chuàng)建listStudent.html，用于顯示內(nèi)容

運(yùn)行效果如下：
