# JavadocViewerService
|
|
|
|
## Preface
|
|
|
|
This project Spring Boot web service that automatically fetches, manages, and serves Javadoc documentation for Maven artifacts.
|
|
|
|
If you encounter any bugs or find missing features, feel free to report them on
|
|
the [Github Issues page](https://github.com/th-schwarz/JavadocViewerService/issues).
|
|
|
|
## Features
|
|
|
|
- Fetches Javadoc JARs from Maven Central or custom Maven repositories
|
|
- Tracks multiple Maven artifacts with version detection
|
|
- Serves generated Javadoc via a simple Bootstrap web UI
|
|
- Scheduled updates via configurable cron expression
|
|
- Persists metadata in an embedded H2 database (Liquibase-managed)
|
|
|
|
## Requirements
|
|
|
|
JRE-21 or docker
|
|
|
|
## Start
|
|
### ... with Java
|
|
|
|
```bash
|
|
java -jar jdvc-<version>.jar --spring.config.import=file:./jdvs.yml
|
|
```
|
|
|
|
### .. with Docker
|
|
|
|
```yaml
|
|
services:
|
|
jvs-dockerized:
|
|
image: git.mein-gateway.de/thischwa/javadocviewerservice:develop
|
|
volumes:
|
|
- /opt/javadocviewerservice-dockerized/jdvs.yml:/app/jdvs.yml:ro
|
|
- /opt/javadocviewerservice-dockerized/database:/app/database
|
|
- /opt/javadocviewerservice-dockerized/javadoc-storage:/app/javadoc-storage
|
|
restart: unless-stopped
|
|
ports:
|
|
- "127.0.0.1:8086:8080"
|
|
```
|
|
|
|
Volume mapping:
|
|
|
|
| Mount | Purpose |
|
|
|---|---|
|
|
| `jdvs.yml:/app/jdvs.yml:ro` | Injects the repository configuration (which artifacts to track) as read-only — the only file you need to edit |
|
|
| `database:/app/database` | Persists the H2 database so tracked version metadata survives restarts and image updates |
|
|
| `javadoc-storage:/app/javadoc-storage` | Persists generated Javadoc HTML so it is not lost on container recreation |
|
|
|
|
|
|
## Configuration
|
|
|
|
### `application.yml`
|
|
|
|
Key defaults:

|
| Property | Default | Description |

|
|
| `jdvs.base-dir` | `./javadoc-storage` | Storage root for generated Javadoc |
|
|
| `jdvs.cron` | `0 0/30 * * * ?` | Update schedule (every 30 min) |
|
|
| `jdvs.clean-on-start` | `false` | Wipe storage and DB on startup |
|
|
| `jdvs.run-on-start` | `false` | Run update immediately on startup |
|
|

|
|

|
### `jdvs.yml`
|
