, introduce Polaris ratelimit starter
<dependency>
<groupId>com.tencent.cloud</groupId>
<artifactId>spring-cloud-starter-tencent-polaris-ratelimit</artifactId>
</dependency>
- Launch Application
Examples provided by Polaris all support to run at IDE, or compile and run with orders
-

-
at Polaris end, through control panel, under namespace Product, add RateLimitCalleeService
-
Launch callee server:
- Launch IDE directly: First find
RateLimitCalleeService
, execute main then launch application - compile package then launch: first execute
mvn clean package
compile the package, then executejava -jar ratelimit-callee-sevice-${verion}.jar
execute the application
- After launching, one can watch server instance from Polaris control panel
- Invoke Service
After visiting http://127.0.0.1:48081/business/invoke, one can see the following information:
