编程

1 导入pom

<!--一定要保证安装的zookeeper版本和导入的包版本一致-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            <exclusions>
                <!--先排除自带的zookeeper3.5.3-->
                <exclusion>
                    <groupId>org.apache.zookeeper</groupId>
                    <artifactId>zookeeper</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <!--添加zookeeper3.4.9版本-->
        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.6</version>
        </dependency>

2 编写yml文件

spring:
  application:
    name: cloud-consumer-order
  cloud:
    zookeeper:
    # 注册到zookeeper地址
      connect-string: localhost:2181

3 在启动类上面开启注解 

@EnableDiscoveryClient

package com.shi.order;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
@EnableDiscoveryClient
public class OrderApplication {
    public static void main(String[] args) {
        SpringApplication.run(OrderApplication.class, args);
    }
}

4 .使用restTemplat进行测试

package com.shi.order.config;
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 ConfigApplication {
    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate() {
        return new RestTemplate();
    }
}

5 . Controller 测试代码

package com.shi.order.controller;
import com.shi.order.entity.CommonResoult;
import com.shi.order.entity.Payment;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
public class OrderController {
    private static String preUrl = "http://cloud-payment-service";
    @Autowired
    private RestTemplate restTemplate;
    @RequestMapping("/consumer/getPort")
    public CommonResoult<String> getPort(){
        CommonResoult<String> resoult = restTemplate.postForObject(preUrl + "/product/getPort",null,CommonResoult.class);
        return resoult;
    }
}
