java spring spring boot loadbalancer 引入与使用

在消费中pom中引入

org.springframework.cloud

spring-cloud-starter-loadbalancer

请求调用加+ @LoadBalanced 注解

进行服务调用

默认负载均衡是轮训模式

 想要切换为随机模式需要重写restTemplate

@Configuration@LoadBalancerClient(         //下面的value值大小写一定要和consul里面的名字一样，必须一样         value = "cloud-payment-service",configuration = RestTemplateConfig.class)public class RestTemplateConfig {     @Bean    @LoadBalanced //使用@LoadBalanced注解赋予RestTemplate负载均衡的能力    public RestTemplate restTemplate(){         return new RestTemplate();     }     @Bean     ReactorLoadBalancer randomLoadBalancer(Environment environment,                                                             LoadBalancerClientFactory loadBalancerClientFactory) {         String name = environment.getProperty(LoadBalancerClientFactory.PROPERTY_NAME);         return new RandomLoadBalancer(loadBalancerClientFactory.getLazyProvider(name, ServiceInstanceListSupplier.class), name);     } }
