Introduction

An extension of spring cloud gateway circuit breaker realizes the fusing of a single instance without affecting other same applications

Spring cloud gateway circuit breaker difference

• Spring cloud gateway circuit breaker will use the same fuse for the same args.name. As long as there is a problem with one instance, the service under the fuse cannot be accessed. In particular, when the "loadbalancerclientfilter" is used for load balancing, configure the fuse. When an instance under load balancing has a problem, triggering the fuse will cause other instances to be inaccessible.

• The instance circuit breaker implements separate fuse calculation for each instance of specific access. When there is a problem in one instance of the same application, the access of other instances will not be affected.

Explanation of terms

In order to prevent conceptual conflicts, special interpretation

• Same application: indicates an application with the same name in the registration center
• Instance: each startup of the application is an instance, and different ports of the same IP are different instances

Instructions

• Add spring-cloud-circuitbreaker-instances dependency

  • Maven:

    <dependency>
        <groupId>com.manymobi</groupId>
        <artifactId>spring-cloud-circuitbreaker-instances</artifactId>
        <version>1.0</version>
    </dependency>

  • Gradle

    compile group: 'com.manymobi', name: 'spring-cloud-circuitbreaker-instances', version: '1.0'

• Example application.yml

  spring:
    cloud:
      gateway:
        routes:
        - id: instancescircuitbreaker_route
          uri: https://example.org
          filters:
          - InstancesCircuitBreaker=myCircuitBreaker
  

• See official documents for other ways of use Just replace filters.name "CircuitBreaker" with "InstancesCircuitBreaker"
