springcloud服务消费端之从消费端直接到服务提供端-03

springcloud入门详细搭建微服务环境-01

springcloud服务提供端-02

springcloud消费端是在以上的基础上搭建的：

1.导入依赖的jar包

<!-- springBoot支持 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- spring boot 测试 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
        <!-- Eureka 客户端依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <!-- spring cloud 核心，自动配置 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>

2.写一个消费服务端的入口类

package cn.mesmile;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
 * @Created with IDEA
 * @author: Super Zheng
 * @Description: java类作用描述
 * @Date:2019/1/6
 * @Time:14:11
    这里演示 直接从 消费端到服务提供端
 */
@SpringBootApplication
public class UserConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(UserConsumerApplication.class);
    }
}

3.写一个config类

package cn.mesmile.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;
/**
 * @Created with IDEA
 * @author: Super Zheng
 * @Description: java类作用描述
 * @Date:2019/1/6
 * @Time:14:15
 */
@Configuration
public class ConfigBean {
    @Bean
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

4.写一个消费端controller类

package cn.mesmile.controller;
import cn.mesmile.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
/**
 * @Created with IDEA
 * @author: Super Zheng
 * @Description: java类作用描述
 * @Date:2019/1/6
 * @Time:14:12
 */
@RestController
@RequestMapping("/consumer")
public class UserController {
    @Autowired
    private RestTemplate restTemplate;
    @RequestMapping("/user/{id}")
    public User getUser(@PathVariable(name = "id") Long id){
        String url = "http://localhost:8001/provider/user/"+id;
        return restTemplate.getForObject(url, User.class);
    }
}

5.写配置文件

server:
  port: 9001
eureka:
  client:
    service-url:
     defaultZone: http://localhost:7001/eureka #告诉服务提供者要把服务注册到哪里
  instance:
    prefer-ip-address: true #显示客户端ip
spring:
  application:
    name: USER-CONSUMER #不要使用下划线
