5.1 查询课程
@RequestMapping(value = "/getByPage", method = RequestMethod.GET) @ApiOperation(value = "查询课程") public Result<IPage<Curriculum>> getByPage(@ModelAttribute Curriculum curriculum ,@ModelAttribute PageVo page){ QueryWrapper<Curriculum> qw = new QueryWrapper<>(); if(!ZwzNullUtils.isNull(curriculum.getTitle())) { qw.like("title",curriculum.getTitle()); } if(!ZwzNullUtils.isNull(curriculum.getType())) { qw.eq("type",curriculum.getType()); } if(!ZwzNullUtils.isNull(curriculum.getLevel())) { qw.eq("level",curriculum.getLevel()); } IPage<Curriculum> data = iCurriculumService.page(PageUtil.initMpPage(page),qw); return new ResultUtil<IPage<Curriculum>>().setData(data); }
5.2 新增学生选课
@RequestMapping(value = "/insert", method = RequestMethod.POST) @ApiOperation(value = "新增选课") public Result<CourseSelection> insert(CourseSelection courseSelection){ Curriculum curriculum = iCurriculumService.getById(courseSelection.getCurriculumId()); if(curriculum == null) { return ResultUtil.error("课程不存在"); } QueryWrapper<CourseSelection> oldQw = new QueryWrapper<>(); oldQw.eq("curriculum_id",courseSelection.getCurriculumId()); oldQw.eq("student_id",courseSelection.getStudentId()); if(iCourseSelectionService.count(oldQw) > 0L) { return ResultUtil.error("已完成选课"); } courseSelection.setTitle(curriculum.getTitle()); courseSelection.setType(curriculum.getType()); courseSelection.setContent(curriculum.getContent()); courseSelection.setKnowledgePoints(curriculum.getKnowledgePoints()); courseSelection.setWeeklyHours(curriculum.getWeeklyHours()); courseSelection.setLevel(curriculum.getLevel()); User student = iUserService.getById(courseSelection.getStudentId()); if(student == null) { return ResultUtil.error("学生不存在"); } courseSelection.setStudentName(student.getNickname()); courseSelection.setGrade(BigDecimal.ZERO); courseSelection.setGradeUser(""); courseSelection.setGradeTime(""); courseSelection.setMakeupExam(""); iCourseSelectionService.saveOrUpdate(courseSelection); return new ResultUtil<CourseSelection>().setData(courseSelection); }
5.3 编辑学生选课
@RequestMapping(value = "/update", method = RequestMethod.POST) @ApiOperation(value = "编辑选课") public Result<CourseSelection> update(CourseSelection courseSelection){ Curriculum curriculum = iCurriculumService.getById(courseSelection.getCurriculumId()); if(curriculum == null) { return ResultUtil.error("课程不存在"); } QueryWrapper<CourseSelection> oldQw = new QueryWrapper<>(); oldQw.eq("curriculum_id",courseSelection.getCurriculumId()); oldQw.eq("student_id",courseSelection.getStudentId()); if(iCourseSelectionService.count(oldQw) > 0L) { return ResultUtil.error("已完成选课"); } courseSelection.setTitle(curriculum.getTitle()); courseSelection.setType(curriculum.getType()); courseSelection.setContent(curriculum.getContent()); courseSelection.setKnowledgePoints(curriculum.getKnowledgePoints()); courseSelection.setWeeklyHours(curriculum.getWeeklyHours()); courseSelection.setLevel(curriculum.getLevel()); User student = iUserService.getById(courseSelection.getStudentId()); if(student == null) { return ResultUtil.error("学生不存在"); } courseSelection.setStudentName(student.getNickname()); iCourseSelectionService.saveOrUpdate(courseSelection); return new ResultUtil<CourseSelection>().setData(courseSelection); }
5.4 课程打分
@RequestMapping(value = "/check", method = RequestMethod.GET) @ApiOperation(value = "打分") public Result<CourseSelection> check(@RequestParam String id,@RequestParam BigDecimal grade){ CourseSelection cs = iCourseSelectionService.getById(id); if(cs == null) { return ResultUtil.error("选课不存在"); } User currUser = securityUtil.getCurrUser(); cs.setGrade(grade); cs.setGradeUser(currUser.getNickname()); cs.setGradeTime(DateUtil.now()); if(grade.compareTo(BigDecimal.valueOf(60)) >= 0) { cs.setMakeupExam("无需补考"); } else { cs.setMakeupExam("补考待安排"); } iCourseSelectionService.saveOrUpdate(cs); return ResultUtil.success(); }
5.5 安排补考
@RequestMapping(value = "/make", method = RequestMethod.GET) @ApiOperation(value = "安排补考") public Result<CourseSelection> make(@RequestParam String id,@RequestParam String makeupExam){ CourseSelection cs = iCourseSelectionService.getById(id); if(cs == null) { return ResultUtil.error("选课不存在"); } cs.setMakeupExam(makeupExam); iCourseSelectionService.saveOrUpdate(cs); return ResultUtil.success(); }
