### 功能点
* 注册&登录
* 多会话(多角色)
* 图片生成(文生图、修图、图生图)
* 提示词
* 额度控制
* 自定义openai secret_key
* 基于大模型的知识库RAG

### 如何部署
#### 初始化
初始化数据库
* 创建数据库aideepin
* 执行docs/create.sql
* 填充openai的secret\_key
```plaintext
update adi_sys_config set value = 'my_chatgpt_secret_key' where name = 'secret_key'
```
* 修改配置文件
* postgresql: application-[dev|prod].xml中的spring.datasource
* redis: application-[dev|prod].xml中的spring.data.redis
* mail: application.xml中的spring.mail
#### 编译及运行
* 进入项目
```plaintext
cd langchain4j-aideepin
```
* 打包:
```
mvn clean package -Dmaven.test.skip=true
```
* 运行
a. jar包启动
```plaintext
cd adi-chat/target
nohup java -jar -Xms768m -Xmx1024m -XX:+HeapDumpOnOutOfMemoryError adi-chat-0.0.1-SNAPSHOT.jar --spring.profiles.active=[dev|prod] dev/null 2>&1 &
```
b. docker启动
```plaintext
cd adi-chat
docker build . -t aideepin:0.0.1
docker run -d \
--name=aideepin \
-e APP_PROFILE=[dev|prod] \
-v="/data/aideepin/logs:/data/logs" \
aideepin:0.0.1
```
