SpringCloud使用Sentinel 代替 Hystrix

本文基于springboot-2.0.6RELEASE+cloud-F.SR2

Feign环境下:只需两步
1.在原使用hystrix的模块中添加如下依赖:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-alibaba-sentinel</artifactId>
    <version>0.2.1.RELEASE</version>
</dependency>
2.在application.yml 中添加feign.sentinel.enabled=true 即可为Feign启用Sentinel支持:

# 去掉
# feign.hystrix.enabled: true
# 改为如下即可
feign.sentinel.enabled: true
Ribbon环境下:
1.先去除Spring Cloud Netflix Hystrix( spring-cloud-starter-netflix-hystrix )的依赖,再添加sentinel依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-alibaba-sentinel</artifactId>
    <version>0.2.1.RELEASE</version>
</dependency>
2.再在构造RestTemplate的时候加上@SentinelRestTemplate注解即可

@Bean
@SentinelRestTemplate
public RestTemplate restTemplate() {
    return new RestTemplate();
}
