SPring cloud （3）A Ribbon 负载均衡 配置初步

1.引用pom

　　　　 <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-ribbon</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

2.修改yml

server:
  port: 80


eureka:
  client:
    register-with-eureka: false
    service-url:
      detaultZone: http://eureka7001.com:7001/eureka/

3.配置类

package com.service.config;

import com.netflix.loadbalancer.IRule;
import com.netflix.loadbalancer.RetryRule;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

@Configuration
public class Dept_Config {

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

    @Bean
    public IRule myRule(){

        return new RetryRule();
    }
}

 4.启动类

@SpringBootApplication
@EnableEurekaClient
public class Dept_Custor {
    public static void main(String[] args){
        SpringApplication.run(Dept_Custor.class,args);
    }
}
