+# Keploy Sample Java - JWT Token Verification and Spring Boot
+
+This repository contains a sample project that demonstrates the integration of Keploy with JWT (JSON Web Token) authentication in a Spring Boot application.
+
+## Prerequisites
+
+Before getting started, make sure you have the following installed:
+
+- Latest version of JDK
+- Install [Keploy](https://keploy.io/docs/server/installation/)
+- Postman for testing APIs
+
+## Getting Started
+
+To get started, clone the repository:
+
+```bash
+git clone https://github.com/jaiakash/samples-java.git
+cd spring-boot-jwt
+```
+
+## API Endpoints
+
+The following API endpoints are available:
+
+#### Login
+
+- POST `/users/login`
+
+  Authenticate a user and receive a JWT token.
+

+  {
+    "username": "your_username",
+    "password": "your_password"
+  }
+  ```

+  {
+    "isValid": true
+  }
+  ```
+
+## Integration with Keploy
+
+#### RECORD Mode
+
+1. To run the application, run
+
+   ```
+   keploy run -c "./mvnw spring-boot:run" --delay 240
+   ```
+
+2. To generate testcases, you can make API calls using Postman or `curl`:
+
+- Login
+
+  ```bash
+  curl --location --request POST 'http://localhost:8080/users/login' \
+  --header 'Content-Type: application/json' \
+  --data-raw '{
+    "username": "[email protected]",
+    "password": "password"
+  }'
+  ```
+
+- Verify
+
+  ```bash
+  curl --location --request POST 'http://localhost:8080/users/verify' \
+  --header 'Content-Type: application/json' \
+  --data-raw '{
+    "token": "your_jwt_token_here"
+  }'
+  ```
+
+#### TEST mode
+
+To test the application, start Keploy in test mode. In the root directory, run the following command:
+
+```bash
+keploy test -c "./mvnw spring-boot:run" --delay 240
+```
+
+This command will run the tests and generate the report in the `Keploy/reports` directory in the current working directory.
