# 一、从hystrix迁移 #

### 1.pom文件替换 ###

<dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
                <version>2.0.0.RELEASE</version>
            </dependency>

使用sentinel替换hystrix

### 2.注解替换 ###

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

使用@SentinelRestTemplate替换@@LoadBalanced

# 二、迁移hystrix-dashboard至sentinel-dashboard #

### 1.下载sentinel-dashoard ###

[https://github.com/alibaba/Sentinel/releases][https_github.com_alibaba_Sentinel_releases]

建议下载源码包

### 2.application.propertres ###

spring.cloud.sentinel.transport.dashboard=localhost:7001

在consumer中添加，这样dashboard就可以自动识别了。

### 3.效果 ###

# 三、项目地址 #

我的项目地址：[https://github.com/sustly/blog\_vue\_server/tree/springcloud\_alibaba][https_github.com_sustly_blog_vue_server_tree_springcloud_alibaba]

注意是springcloud\_alibaba分支，springcloud\_netflix是已经完善的
