# Spring Cloud Polaris Quickstart example
English | [简体中文](./README-zh.md)
---
## Introduction
This example shows how to make application integrated with spring-cloud-tencent rapidly.
## Instruction
### Configuration
Modify ```bootstrap.yml```, ${ip} and ${port} is the address of polaris server.
```yaml
spring:
application:
name:EchoService
cloud:
polaris:
address:grpc://${ip}:${port}
```
### Start Application
#### Start Provider
- Start in IDEA
Find main class ```EchoServerApplication``` in project ```polaris-quickstart-example/quickstart-provider```, and execute the main method.
- Start by fatjar
Run build command in ```polaris-quickstart-example/quickstart-provider```:
```sh
mvn clean package
```
find the generated fatjar, run:
```
java -jar ${app.jar}
```
${app.jar} replace to the built jar name.
#### Start Consumer
- Start in IDEA
Find main class ```EchoClientApplication``` in project ```polaris-quickstart-example/quickstart-consumer```, and execute the main method.
- Start by fatjar
Run build command in ```polaris-quickstart-example/quickstart-consumer```:
```sh
mvn clean package
```
find the generated fatjar, run:
```
java -jar ${app.jar}
```
${app.jar} replace to the built jar name.
### Verify
#### Invoke by http call
Consumer and Provider application use random generated port, so you need to record the consumer port from start log.
```
11:26:53 [main] INFO o.s.b.w.e.tomcat.TomcatWebServer - Tomcat started on port(s): 58838 (http) with context path ''
```
Invoke http call，replace `${app.port}` to the consumer port.
```shell
curl -L -X GET 'http://localhost:47080/quickstart/feign?msg=hello_world''
