|
||||||
|
|
||||||
## Example Introduction
|
|
||||||
|
|
||||||
This example shows how to use```spring-cloud-starter-tencent-polaris-circuitbreaker```in Spring Cloud project for its features.
|
|
||||||
|
|
||||||
This example contains callee-service```polaris-circuitbreaker-callee-service```、```polaris-circuitbreaker-callee-service2```and caller-service```polaris-circuitbreaker-feign-example```、```polaris-circuitbreaker-gateway-example```、```polaris-circuitbreaker-webclient-example```.

# Spring Cloud Polaris Discovery example
|
|
||||||
|
|
||||||
## Example Introduction
|
|
||||||
|
|
||||||
This example shows how to use ```spring-cloud-starter-tencent-polaris-discovery`` in Spring Cloud project for its features.
|
|
||||||
|
|
||||||
This example is divided to two microservice, discovery-caller-service and discovery-callee-service. In these two microservices, discovery-caller-service invokes discovery-callee-service.
|
|
||||||
|
|
||||||
## Instruction
|
|
||||||
|
|
||||||
### Configuration
|
|
||||||
|
|
||||||
The configuration is as the following shows. ${ip} and ${port} are Polaris backend IP address and port number.
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
spring:
|
|
||||||
application:
|
|
||||||
name: ${application.name}
|
|
||||||
cloud:
|
|
||||||
polaris:
|
|
||||||
address: ${ip}:${port}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Launching Example
|
|
||||||
|
|
||||||
#### Launching Polaris Backend Service

|
|
||||||
|
|
||||||
#### Launching Application
|
|
||||||
|
|
||||||
- IDEA Launching
|
|
||||||
|
|
||||||
Launching ```spring-cloud-tencent-examples/polaris-discovery-example/discovery-caller-service```'s ```DiscoveryCallerService``` and ```spring-cloud-tencent-examples/polaris-discovery-example/discovery-callee-service```'s ```DiscoveryCalleeService```
|
|
||||||
|
|
||||||
- Maven Package Launching
|
|
||||||
|
|
||||||
Execute under ```spring-cloud-tencent-examples/polaris-discovery-example```
|
|
||||||
|
|
||||||
```sh
|
|
||||||
mvn clean package
|
|
||||||
```
|
|
||||||
|
|
||||||
Then at ```discovery-caller-service``` and ```discovery-callee-service``` find the package that generates jar, and run it
|
|
||||||
|
|
||||||
```
|
|
||||||
java -jar ${app.jar}
|
|
||||||
```
|
|
||||||
|
|
||||||
Launch application, change ${app.jar} to jar's package name

|
||||||
```shell
|
|
||||||
curl -L -X GET 'http://localhost:48080/discovery/service/caller/feign?value1=1&value2=2'
|
|
||||||
```

# Spring Cloud Polaris Gateway example
|
|
||||||
|
|
||||||
## Example Introduction
|
|
||||||
|
|
||||||
This example shows how to use ```spring-cloud-tencent-polaris-gateway``` in Spring Cloud project for its features.
|
|
||||||
|
|
||||||
This example contains ```gateway-zuul-service```, ```gateway-scg-service``` and ```gateway-callee-service```. ```gateway-zuul-service``` and ```gateway-scg-service``` invoke ```gateway-callee-service```.
|
|
||||||
|
|
||||||
## Instruction
|
|
||||||
|
|
||||||
### Configuration
|
|
||||||
|
|
||||||
The configuration is as the following shows. ${ip} and ${port} are Polaris backend IP address and port number.
|
|
||||||
|
|
||||||
```yaml
|
|
||||||
spring:
|
|
||||||
application:
|
|
||||||
name: ${application.name}
|
|
||||||
cloud:
|
|
||||||
polaris:
|
|
||||||
address: ${ip}:${port}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Launching Example
|
|
||||||
|
|
||||||
#### Launching Polaris Backend Service
|
|
||||||
|
|
||||||
Reference to [Polaris Getting Started](https://github.com/PolarisMesh/polaris#getting-started)
|
|
||||||
|
|
||||||
#### Launching Application
|
|
||||||
|
|
||||||
- IDEA Launching
|
|
||||||
|
|
||||||
Launching ```spring-cloud-tencent-examples/polaris-gateway-example/gateway-zuul-service```'s ```GatewayZuulService```, ```spring-cloud-tencent-examples/polaris-gateway-example/gateway-scg-service```'s ```GatewayScgService``` and ```spring-cloud-tencent-examples/polaris-gateway-example/gateway-callee-service```'s ```GatewayCalleeService```
|
|
||||||
|
|
||||||
- Maven Package Launching
|
|
||||||
|
|
||||||
Execute under ```spring-cloud-tencent-examples/polaris-gateway-example```
|
|
||||||
|
|
||||||
```sh
|
|
||||||
mvn clean package
|
|
||||||
```
|
|
||||||
|
|
||||||
Then find the jars under ```gateway-zuul-service```, ```gateway-scg-service``` and ```gateway-callee-service```, and run it:
|
|
||||||
|
|
||||||
```
|
|
||||||
java -jar ${app.jar}
|
|
||||||
```
|
|
||||||
|
|
||||||
Launch application, change ${app.jar} to jar's package name.
|
|
||||||
|
|
||||||
### Verify
|
|
||||||
|
|
||||||
#### Zuul Invoke
|
|
||||||
|
|
||||||
```shell
|
|
||||||
curl -L -X GET 'http://localhost:48082/GatewayCalleeService/gateway/example/callee/echo' -H 'SCT-CUSTOM-METADATA: {"b": 2}'
|
|
||||||
```
|
|
||||||
|
|
||||||
Expected return rate
|
|
||||||
|
|
||||||
```
|
|
||||||
{"a":"1","b":2}
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Spring-Cloud-Gateway Invoke
|
|
||||||
|
|
||||||
```shell
|
|
||||||
curl -L -X GET 'http://localhost:48083/GatewayCalleeService/gateway/example/callee/echo' -H 'SCT-CUSTOM-METADATA: {"b": 2}'
|
|
||||||
```
|
|
||||||
|
|
||||||
Expected return rate
|
|
||||||
|
|
||||||
```
|
|
||||||
{"a":"1","b":2}
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Gateway Rate Limit
|
|
||||||

# Spring Cloud Polaris RateLimit Example
|
|
||||||
|
|
||||||
## Project Explanation
|
|
||||||
|
|
||||||
This project shows how to use ratelimit feature of Polaris to complete Spring Cloud application's rate limit
|
|
||||||
|
|
||||||
## Example
|
|
||||||
|
|
||||||
### How to access
|
|
||||||
|
|
||||||
Before showcasing the project, let's get to know how to access Polaris rate limit component
|
|
||||||
|
|
||||||
> ** note: this chapter is to help you understand different ways to access, the codes in the example has been executed, you don't need to re-edit.**
|
|
||||||
|
|
||||||
1, first, change document `pom.xml`, introduce Polaris ratelimit starter
|
|
||||||
|
|
||||||
```xml
|
|
||||||
<dependency>
|
|
||||||
<groupId>com.tencent.cloud</groupId>
|
|
||||||
<artifactId>spring-cloud-starter-tencent-polaris-ratelimit</artifactId>
|
|
||||||
</dependency>
|
|
||||||
```
|
|
||||||
|
|
||||||
2. Launch Application
|
|
||||||
|
|
||||||
Examples provided by Polaris all support to run at IDE, or compile and run with orders
|
|
||||||
|
|
||||||
- Launch Polaris locally
|
|
||||||
|
|
||||||
- at Polaris end, through control panel, under namespace Product, add RateLimitCalleeService
|
|
||||||
|
|
||||||
- Launch callee server:
|
|
||||||
|
|
||||||
1. Launch IDE directly: First find `RateLimitCalleeService`, execute main then launch application
|
|
||||||
2. compile package then launch: first execute `mvn clean package` compile the package, then execute `java -jar ratelimit-callee-sevice-${verion}.jar` execute the application
|
|
||||||
|
|
||||||
- After launching, one can watch server instance from Polaris control panel
|
|
||||||
|
|
||||||
3. Invoke Service
|
|
||||||
|
|
||||||
After visiting http://127.0.0.1:48081/business/invoke, one can see the following information:
|
|
||||||
|
|
||||||
````
|
|
||||||
hello world for ratelimit service 1
|
|
||||||
hello world for ratelimit service 2
|
|
||||||
hello world for ratelimit service 3
|
|
||||||
...
|
|
||||||
````
|
|
||||||
|
|
||||||
4. Configuration rate limit and verification
|
|
||||||
Polaris provide three wats to conduct rate limit configuration (control panel, HTTP port and local files)
|
|
||||||
|
|
||||||
this example is HTTP configuration. One can figure with the following steps:
|
|
||||||
|
|
||||||
````
|
|
||||||
curl -X POST -H "Content-Type:application/json" 127.0.0.1:8090/naming/v1/ratelimits -d @rule.json
|
|
||||||
````
|
|
||||||
|
|
||||||
5. Verify rate limit result
|
|
||||||
continue visit http://127.0.0.1:48081/business/invoke, one can see, after 10 invokes, rate limit will start:
|
|
||||||
|
|
||||||
````
|
|
||||||
hello world for ratelimit service 1
|
|
||||||
hello world for ratelimit service 2
|
|
||||||
|
|
||||||
````
