五、核心代码
5.1 一键生成实验
@RequestMapping(value = "/oneCreateExp", method = RequestMethod.GET) @ApiOperation(value = "一键生成实验") public Result<Object> oneCreateExp(@RequestParam String id){ ExperimentCurriculum curriculum = iExperimentCurriculumService.getById(id); if(curriculum == null) { return ResultUtil.error("实验不存在"); } // 删除原来的 QueryWrapper<Experiment> oldQw = new QueryWrapper<>(); oldQw.eq("curriculum_id",curriculum.getId()); iExperimentService.remove(oldQw); // 生成新的 QueryWrapper<User> userQw = new QueryWrapper<>(); userQw.eq("type",0); List<User> studentList = iUserService.list(userQw); for (User stu : studentList) { Experiment e = new Experiment(); e.setCurriculumId(curriculum.getId()); e.setCurriculumName(curriculum.getTitle()); e.setStudentId(stu.getId()); e.setStudentName(stu.getNickname()); e.setExpResult(""); e.setExpReport(""); e.setUploadTime(""); e.setGrade(BigDecimal.ZERO); e.setCheckFlag(false); e.setCheckTime(""); e.setCheckUser(""); iExperimentService.saveOrUpdate(e); } return ResultUtil.success(); }
5.2 提交实验
@RequestMapping(value = "/upload", method = RequestMethod.GET) @ApiOperation(value = "提交实验") public Result<Object> upload(@RequestParam String id,@RequestParam String result,@RequestParam String url){ Experiment exp = iExperimentService.getById(id); if(exp == null) { return ResultUtil.error("实验不存在"); } exp.setExpResult(result); exp.setExpReport(url); exp.setUploadTime(DateUtil.now()); iExperimentService.saveOrUpdate(exp); return ResultUtil.success(); }
5.3 批阅实验
@RequestMapping(value = "/check", method = RequestMethod.GET) @ApiOperation(value = "批阅实验") public Result<Object> check(@RequestParam String id,@RequestParam BigDecimal grade){ Experiment exp = iExperimentService.getById(id); if(exp == null) { return ResultUtil.error("实验不存在"); } User currUser = securityUtil.getCurrUser(); exp.setGrade(grade); exp.setCheckFlag(true); exp.setCheckTime(DateUtil.now()); exp.setCheckUser(currUser.getNickname()); iExperimentService.saveOrUpdate(exp); return ResultUtil.success(); }
5.4 新增实验资源
@RequestMapping(value = "/insert", method = RequestMethod.POST) @ApiOperation(value = "新增实验资源") public Result<ExperimentResources> insert(ExperimentResources experimentResources){ ExperimentCurriculum curriculum = iExperimentCurriculumService.getById(experimentResources.getCurriculumId()); if(curriculum == null) { return ResultUtil.error("实验课程不存在"); } experimentResources.setCurriculumName(curriculum.getTitle()); String fileUrl = experimentResources.getFileUrl(); if(!ZwzNullUtils.isNull(fileUrl)) { String[] split = fileUrl.split("/"); File f = iFileService.getById(split[split.length - 1]); if(f != null) { experimentResources.setFileId(f.getId()); experimentResources.setFileName(f.getName()); experimentResources.setFileSize(f.getSize()); } } iExperimentResourcesService.saveOrUpdate(experimentResources); return new ResultUtil<ExperimentResources>().setData(experimentResources); }
5.5 查询实验课程
@RequestMapping(value = "/getByPage", method = RequestMethod.GET) @ApiOperation(value = "查询实验课程") public Result<IPage<ExperimentCurriculum>> getByPage(@ModelAttribute ExperimentCurriculum experimentCurriculum ,@ModelAttribute PageVo page){ QueryWrapper<ExperimentCurriculum> qw = new QueryWrapper<>(); User currUser = securityUtil.getCurrUser(); QueryWrapper<User> userQw = new QueryWrapper<>(); userQw.eq("id",currUser.getId()); userQw.inSql("id","SELECT user_id FROM a_user_role WHERE del_flag = 0 AND (role_id = '1536606659751841795' OR role_id = '1536606659751841799')"); if(iUserService.count(userQw) < 1L) { qw.eq("teacher_id",currUser.getId()); } if(!ZwzNullUtils.isNull(experimentCurriculum.getTitle())) { qw.like("title",experimentCurriculum.getTitle()); } if(!ZwzNullUtils.isNull(experimentCurriculum.getContent1())) { qw.like("content1",experimentCurriculum.getContent1()); } if(!ZwzNullUtils.isNull(experimentCurriculum.getTeacherName())) { qw.like("teacher_name",experimentCurriculum.getTeacherName()); } IPage<ExperimentCurriculum> data = iExperimentCurriculumService.page(PageUtil.initMpPage(page),qw); return new ResultUtil<IPage<ExperimentCurriculum>>().setData(data); }
