## 📖 Documentation

[![Vault Setup Guide](https://img.shields.io/badge/📘_Vault_Setup_Guide-Click_Here-blue?style=for-the-badge)](./VAULT_SETUP.md)




## 🚀 How to Run

1. **Start Vault** (See Documentation section above)

2. **Run the Application**

```sh

./gradlew bootRun

The application will start on http://localhost:8080

```




## 🔌 API Endpoints

### Test Endpoint

**GET** `http://localhost:8080/hello`

Returns the secret value from Vault.

### Refresh Configuration

**POST** `http://localhost:8080/actuator/refresh`

Refreshes the application configuration from Vault without restarting the application.

**Example with cURL:**

```bash

curl -X POST http://localhost:8080/actuator/refresh

```

📸 Click to see the refresh response



The response shows which configuration properties were successfully reloaded from Vault.




## 🔄 Dynamic Configuration Update

This project uses `@RefreshScope` to enable dynamic configuration updates:

Update your secret value in Vault

Call the refresh endpoint: POST http://localhost:8080/actuator/refresh

The new value will be reflected immediately without restarting the application

**Example Flow:**

```sh

# 1. Check current value

curl http://localhost:8080/hello

# 2. Update value in Vault UI

# 3. Refresh configuration

curl -X POST http://localhost:8080/actuator/refresh

# 4. Check updated value

curl http://localhost:8080/hello

```
