Vue.js+SpringBoot开发计算机机房作业管理系统-五、核心代码

5.1 查询课程数据

@RequestMapping(value = "/getByPage", method = RequestMethod.GET)
@ApiOperation(value = "查询课程")
public Result<IPage<Course>> getByPage(@ModelAttribute Course course ,@ModelAttribute PageVo page){
    QueryWrapper<Course> qw = new QueryWrapper<>();
    if(!ZwzNullUtils.isNull(course.getTitle())) {
        qw.like("title",course.getTitle());
    }
    if(!ZwzNullUtils.isNull(course.getTeacherName())) {
        qw.like("teacher_name",course.getTeacherName());
    }
    IPage<Course> data = iCourseService.page(PageUtil.initMpPage(page),qw);
    return new ResultUtil<IPage<Course>>().setData(data);
}

5.2 新增课时

@RequestMapping(value = "/insert", method = RequestMethod.POST)
@ApiOperation(value = "新增课时")
public Result<ClassHour> insert(ClassHour classHour){
    Course course = iCourseService.getById(classHour.getCourseId());
    if(course == null) {
        return ResultUtil.error("课程不存在");
    }
    classHour.setCourseName(course.getTitle());
    iClassHourService.saveOrUpdate(classHour);
    return new ResultUtil<ClassHour>().setData(classHour);
}

5.3 提交作业

@RequestMapping(value = "/upload", method = RequestMethod.GET)
@ApiOperation(value = "提交作业")
public Result<Task> upload(@RequestParam String id,@RequestParam String url){
    Task task = iTaskService.getById(id);
    if(task == null) {
        return ResultUtil.error("作业不存在");
    }
    task.setUploadTime(DateUtil.now());
    task.setTask(url);
    iTaskService.saveOrUpdate(task);
    return ResultUtil.success();
}

5.4 批阅作业

@RequestMapping(value = "/check", method = RequestMethod.GET)
@ApiOperation(value = "批阅作业")
public Result<Task> check(@RequestParam String id,@RequestParam BigDecimal grade){
    Task task = iTaskService.getById(id);
    if(task == null) {
        return ResultUtil.error("作业不存在");
    }
    User currUser = securityUtil.getCurrUser();
    task.setCheckId(currUser.getId());
    task.setCheckName(currUser.getNickname());
    task.setCheckTime(DateUtil.now());
    task.setGrade(grade);
    iTaskService.saveOrUpdate(task);
    return ResultUtil.success();
}
