经典项目学生信息管理系统SpringBoot+MyBatis-Plus+Layui (展示+源码）

项目简介

学生管理系统（student management system），前端使用Layui开发，后端使用Springboot + MyBatis plus 快速开发，项目实现了基本的增、（可批量）删、改以及分页条件查询。数据库使用常见MySQL。

Controller简单案例

@Controller
@RequestMapping("/student")
public class StudentController {

    @Autowired
    private IStudentService studentService;

    @GetMapping("/toView")
    public String index() {
        return "Student";
    }

    @GetMapping("/toEditView")
    public String toAddView() {
        return "Student_edit";
    }

    @GetMapping("/")
    @ResponseBody
    public ResultDto findAll() {
        ResultDto success = success(studentService.list());
        success.setCount((int) studentService.count());
        return success;
    }

    @PostMapping("/findByParamAndLimit")
    @ResponseBody
    public ResultDto findByParam(String studentString, Integer limit, Integer page) {
        Student student = JSONUtil.toBean(studentString, Student.class);
        QueryWrapper<Student> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq(student.getId() != null, "id", student.getId());
        queryWrapper.like(Strings.isNotBlank(student.getName()), "name", student.getName());
        queryWrapper.like(Strings.isNotBlank(student.getPassword()), "password", student.getPassword());
        queryWrapper.like(Strings.isNotBlank(student.getSex()), "sex", student.getSex());
        queryWrapper.like(Strings.isNotBlank(student.getPhone()), "phone", student.getPhone());
        queryWrapper.like(Strings.isNotBlank(student.getEmail()), "email", student.getEmail());
        queryWrapper.like(Strings.isNotBlank(student.getClassName()), "class_name", student.getClassName());
        Page<Student> studentPage = studentService.page(new Page<>(page, limit), queryWrapper);
        ResultDto success = success(studentPage.getRecords());
        success.setCount((int) studentPage.getTotal());
        return success;
    }

    @GetMapping("/{id}")
    @ResponseBody
    public ResultDto findById(@PathVariable String id) {
        return success(studentService.getById(id));
    }

    @PostMapping("/add")
    @ResponseBody
    public ResultDto add(@RequestBody Student student) {
        return success(studentService.save(student));
    }

    @PostMapping("/update")
    @ResponseBody
    public ResultDto update(@RequestBody Student student) {
        return success(studentService.updateById(student));
    }

    @GetMapping("/delete/{id}")
    @ResponseBody
    public ResultDto delete(@PathVariable String id) {
        return success(studentService.removeById(id));
    }

    @PostMapping("/deleteBatch")
    @ResponseBody
    public ResultDto delete(@RequestBody List<String> ids) {
        return success(studentService.removeBatchByIds(ids));
    }

}
