# 学习记录问题诊断清单
|
|||
|
|
|
|||
|
|
## 1. 检查后端是否重新编译
|
|||
|
|
|
|||
|
|
### 问题症状
|
|||
|
|
- 后台管理系统显示的进度还是 57% 或 78.33%
|
|||
|
|
- 而不是 11.11%（3/27）
|
|||
|
|
|
|||
|
|
### 解决方案
|
|||
|
|
```bash
|
|||
|
|
cd C:\Users\Administrator\Desktop\Project\ry_study-v_03\Study-Vue-redis
|
|||
|
|
mvn clean package -DskipTests
|
|||
|
|
# 重启后端服务
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 验证方法
|
|||
|
|
查看后端日志，应该看到：
|
|||
|
|
```
|
|||
|
|
课程 1 进度计算完成: 3个已完成 / 27个有效课件 = 11.11%
|
|||
|
|
```

|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 验证方法
|
|||
|
|
查看App日志，应该看到：
|
|||
|
|
```
|
|||
|
|
[课程学习] 检测到filePath包含profile/前缀，已自动去除
|
|||
|
|
[课程学习] 完整URL: http://192.168.1.164:30091/profile/upload/...

|
## 3. 检查数据库数据
|
|||
|
|
|
|||
|
|
### 执行SQL
|
|||
|
|
```sql
|
|||
|
|
-- 1. 查看课件时长
|
|||
|
|
SELECT id, name, type, duration
|
|||
|
|
FROM courseware
|
|||
|
|
WHERE course_id = 1
|
|||
|
|
ORDER BY id;
|
|||
|
|
|
|||
|
|
-- 2. 查看学习详情
|
|||
|
|
SELECT
|
|||
|
|
id,
|
|||
|
|
courseware_id,
|
|||
|
|
video_end_position as video_position,
|
|||
|
|
duration,
|
|||
|
|
learn_time
|
|||
|
|
FROM learning_detail
|
|||
|
|
WHERE student_id = 452 AND course_id = 1
|
|||
|
|
ORDER BY learn_time DESC
|
|||
|
|
LIMIT 10;
|
|||
|
|
|
|||
|
|
-- 3. 查看学习记录
|
|||
|
|
SELECT
|
|||
|
|
id,
|
|||
|
|
progress,
|
|||
|
|
total_duration,
|
|||
|
|
learn_count,
|
|||
|
|
last_learn_time
|
|||
|
|
FROM learning_record
|
|||
|
|
WHERE student_id = 452 AND course_id = 1;
|
|||
|
|
```
|

|||
|
|
```bash
|
|||
|
|
# 后端

|||
|
|
cd Study-Vue-redis
|
|||
|
|
mvn clean
|
|||
|
|
|
|||
|
|
# 前端UI

cd ry-study-ui
|
|||
|
|
rm -rf node_modules/.cache
