第八天、点播管理模块（二）

一、发布课程-创建课程大纲

1、课程章节接口

实现课程章节的列表、添加、修改和删除功能

1.1、编写章节Controller

@RestController
@RequestMapping(value="/admin/vod/chapter")
@CrossOrigin
public class ChapterController {

    @Autowired
    private ChapterService chapterService;

    //获取章节小结列表
    @ApiOperation("嵌套章节数据列表")
    @GetMapping("getNestedTreeList/{courseId}")
    public Result getNestedTreeList(
            @ApiParam(value = "课程ID", required = true)
            @PathVariable Long courseId){

        List<ChapterVo> chapterVoList = chapterService.getNestedTreeList(courseId);
        return Result.ok(chapterVoList);
    }

    //2 添加章节
    @PostMapping("save")
    public Result save(@RequestBody Chapter chapter) {
        chapterService.save(chapter);
        return Result.ok(null);
    }

    //3 修改-根据id查询
    @GetMapping("get/{id}")
    public Result get(@PathVariable Long id) {
        Chapter chapter = chapterService.getById(id);
        return Result.ok(chapter);
    }

    //4 修改-最终实现
    @PostMapping("update")
    public Result update(@RequestBody Chapter chapter) {
        chapterService.updateById(chapter);
        return Result.ok(null);
    }

    //5 删除章节
    @DeleteMapping("remove/{id}")
    public Result remove(@PathVariable Long id) {
        chapterService.removeById(id);
        return Result.ok(null);
    }
}
