1. Abstract
1.1 System introduction
The online course teaching system based on JAVA+Vue+SpringBoot+MySQL includes course type module, course file module, class file module, class collection module, class comment module, and also includes the system's own user management, department management, and role management. , menu management, log management, data dictionary management, file management, chart display and other basic modules, the online course teaching system has role-based access control for students, teachers, and university administrators. The permissions can be precise to the button level. You can Customize roles and assign permissions, and the system is suitable for designing precise permission restriction requirements.

2. Research content
The IT online course system is a system for students to learn online. The IT training online course system is used by universities or training institutions. It supports the two roles of teachers and students. Teachers can maintain training course types, training course files, and training course files. During the class period, students can watch the course videos, collect and comment on their favorite classes, and complete interactive operations.
module. The basic module of the system includes basic user management, file management, log management, and data dictionary management. The training course module includes a training course type module and a training course archive module, which are used to add, delete, modify, check and maintain data. Class hours are sub-contents under training courses. A course will have multiple class hours for students to learn. The course interaction module includes collection and comment functions for students and teachers to interact.
In general, the IT training online course system can realize students' online learning, conforms to the digital teaching concept, and can reduce teachers' workload.
2.1 Course type management module
The course type management module is used by administrators to maintain course type data, including type name, status, sorting value, remarks, creation time, creator, last updated time, and last updated person information.
2.2 Course Management Module
The course management module is used by administrators to maintain course data, including course name, course classification, course introduction, instructor, pictures, notes, creator, creation time and other information.
2.3 Class management module
The class management module is used by administrators to maintain class data, including class name, class introduction, courses, knowledge points, videos, notes, creator, creation time and other information.
2.4 Course interactive module
The course interaction module is used by administrators to maintain class interaction information, which mainly includes class comments and class collections. The class collection module includes course name, class name, collector, collection time, creation time, creator, last update time, and last updater information; the class comment module includes course name, class name, reviewer, comment time, creation time, Creator, last updated time, comment content information.
2.5 System basic modules
The basic modules of the system include user management, department management, file management, authority management and data dictionary management modules. Since the basic modules of the system are built into the development framework, there is no need to carry out system logic design.

5.1 New course types
@RequestMapping(value = "/insert", method = RequestMethod.POST)
@ApiOperation(value = "新增培训课程类型")
public Result<TrainType> insert(TrainType trainType){
if(trainType.getSortOrder() == null || Objects.equals(0,trainType.getSortOrder().compareTo(BigDecimal.ZERO))) {
trainType.setSortOrder(BigDecimal.valueOf(iTrainTypeService.count() + 1));
}
iTrainTypeService.saveOrUpdate(trainType);
return new ResultUtil<TrainType>().setData(trainType);
}
5.2 Website login
@RequestMapping(value = "/loginOnWeb", method = RequestMethod.GET)
@ApiOperation(value = "网站前台登陆")
public Result<String> loginOnWeb(@RequestParam String userName, @RequestParam String password){
QueryWrapper<User> qw = new QueryWrapper<>();
qw.eq("username",userName);
List<User> userList = iUserService.list(qw);
if(userList.size() < 1) {
return ResultUtil.error("用户不存在");
}
User user = userList.get(0);
if(!new BCryptPasswordEncoder().matches(password, user.getPassword())){
return ResultUtil.error("密码不正确");
}
String accessToken = securityUtil.getToken(user.getUsername(), true);
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(new SecurityUserDetails(user), null, null);
SecurityContextHolder.getContext().setAuthentication(authentication);
return new ResultUtil<String>().setData(accessToken);
}
5.3 Lesson Collection
@RequestMapping(value = "/addOne", method = RequestMethod.GET)
@ApiOperation(value = "新增收藏")
public Result<TrainCollection> addOne(@RequestParam String id){
TrainItem ti = iTrainItemService.getById(id);
if(ti == null) {
return ResultUtil.error("课时不存在");
}
User currUser = securityUtil.getCurrUser();
QueryWrapper<TrainCollection> qw = new QueryWrapper<>();
qw.eq("user_id",currUser.getId());
qw.eq("item_id",ti.getId());
if(iTrainCollectionService.count(qw) > 0L) {
return ResultUtil.success("您已收藏");
}
TrainCollection tc = new TrainCollection();
tc.setItemId(ti.getId());
tc.setItemName(ti.getTitle());
tc.setVideo(ti.getVideo());
tc.setUserId(currUser.getId());
tc.setUserName(currUser.getNickname());
tc.setTime(DateUtil.now());
iTrainCollectionService.saveOrUpdate(tc);
return ResultUtil.success();
}
5.4 Class comments
@RequestMapping(value = "/addOne", method = RequestMethod.GET)
@ApiOperation(value = "新增评论")
public Result<TrainComment> addOne(@RequestParam String id,@RequestParam String content){
TrainItem item = iTrainItemService.getById(id);
if(item == null) {
return ResultUtil.error("课时不存在");
}
User currUser = securityUtil.getCurrUser();
TrainComment tc = new TrainComment();
tc.setItemId(item.getId());
tc.setItemName(item.getTitle());
tc.setUserId(currUser.getId());
tc.setUserName(currUser.getNickname());
tc.setTime(DateUtil.now());
tc.setContent(content);
iTrainCommentService.saveOrUpdate(tc);
return ResultUtil.success();
}
