spring cloud之ribbon

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
eureka该jar中已集成ribbon，无需在引用，若非引用也无碍

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
</dependency>

代码如下
@Configuration
public class ApplicationContextConfig {

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

修改ribbon负载均衡策略（默认轮询）--配置不能被被@ComponentScan扫描（@SpringBootApplication中包含@ComponentScan）

1随机

代码如下

@Configuration
public class MySelfRule {

    @Bean
    public IRule myRule(){
        //TODO 定义为随机
        return new RandomRule();
    }

}
