SpringCloud微服务(基于Eureka+Feign+Hystrix+Zuul)
一、搭建注册中心
1.1、创建一个cloud-service项目

1 package com.tiandy.myclient;
2
3 import org.springframework.boot.SpringApplication;
4 import org.springframework.boot.autoconfigure.SpringBootApplication;
5 import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
6 import org.springframework.cloud.netflix.hystrix.EnableHystrix;

8 @EnableEurekaClient
9 @EnableHystrix
10 @SpringBootApplication
11 public class MyClientApplication {
12
13 public static void main(String[] args) {
14 SpringApplication.run(MyClientApplication.class, args);
15 }
16 }
说明：@EnableEurekaClient是开启Eureka服务注册中心功能注解，@EnableHystrix是开始Hystrix功能注解
1.5：启动MyClientApplication 服务
服务启动成功后，访问http://127.0.0.1:8761/
二、spring cloud创建服务提供者

10
11 hystrix:
12 command:
13 default:
14 execution:
15 isolation:
16 thread:

2.4：实例类VO-User

5
6 @Data
7 public class User implements Serializable {

18 "id='" + id + '\'' +
19 ", name='" + name + '\'' +
20 ", age=" + age +
21 '}';
22 }
23 }
2.5：HelloController业务控制类
1 package com.tiandy.myclient.controller;
2 import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;
3 import com.tiandy.myclient.vo.User;
4 import org.springframework.web.bind.annotation.PathVariable;
5 import org.springframework.web.bind.annotation.RequestMapping;
6 import org.springframework.web.bind.annotation.RestController;
7 @RestController
8 public class HelloController {
9
10 @RequestMapping("/hello/{fallback}")
11 @HystrixCommand(fallbackMethod="fallbackMethod")/*调用方式失败后调用helloFallbackMethod*/
12 public String hello(@PathVariable("fallback") String fallback){
13 if("1".equals(fallback)){
14 throw new RuntimeException("...");
15 }
16 return "走网关了: hello zuul !";
17 }
18
19 public String fallbackMethod(String fallback){
20 return "【触发了Hystrix熔断机制,调用了fallbackMethod方法...】";
21 }
22
23 @RequestMapping("/getUserById/{fallback}")
24 public String getUserById(@PathVariable("fallback") String fallback){
25 User user=new User();
26 user.setId("101");
27 user.setAge(32);
28 user.setName("司藤");
29 if(!fallback.equals("101")){
30 throw new RuntimeException("...");
31 }
32 String userInfo=user.toString();
33 System.out.println(userInfo);
34 return userInfo;
35 }
36 }
2.6：服务启动类MyClientApplication
1 package com.tiandy.myclient;
2
3 import org.springframework.boot.SpringApplication;
4 import org.springframework.boot.autoconfigure.SpringBootApplication;
5 import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
6 import org.springframework.cloud.netflix.hystrix.EnableHystrix;
7
8 @EnableEurekaClient
9 @EnableHystrix
10 @SpringBootApplication
11 public class MyClientApplication {
12
13 public static void main(String[] args) {
14 SpringApplication.run(MyClientApplication.class, args);
15 }
16 }
2.7：启动服务，看服务product-client是否注册到了注册中心
启动成功后，访问http://127.0.0.1:8761/
三、spring cloud创建服务消费者
3.1、创建一个my-consumert项目
3.2：POM文件依赖

3.3：application.yml配置文件
1 server:
2 port: 8082
3 spring:
4 application:
5 name: consumer-client #为你的应用起个名字，该名字将注册到eureka注册中心
6 eureka:
7 client:
8 serviceUrl:
9 defaultZone: http://localhost:8761/eureka/ #去哪里注册，eureka服务地址
3.4：远程接口调用HelloService
1 package com.tiandy.myconsumer.service;
2
3 import org.springframework.cloud.netflix.feign.FeignClient;
4 import org.springframework.web.bind.annotation.PathVariable;
5 import org.springframework.web.bind.annotation.RequestMapping;
6
7 @FeignClient("product-client") //product-client提供接口工程的服务名
8 public interface HelloService {
9
10 @RequestMapping("/hello/{fallback}")
11 public String hello(@PathVariable("fallback") String fallback);
12
13 @RequestMapping("/getUserById/{fallback}")
14 public String getUserById(@PathVariable("fallback") String fallback);
15 }
注意：@FeignClient注解就是开启远程调用的功能，提供的接口必须和product-client工程服务中提供的接口名称、参数、返回值一样
3.5：业务控制类HelloController
1 package com.tiandy.myconsumer.controller;
2
3 import com.tiandy.myconsumer.service.HelloService;
4 import org.springframework.beans.factory.annotation.Autowired;
5 import org.springframework.web.bind.annotation.PathVariable;
6 import org.springframework.web.bind.annotation.RequestMapping;
7 import org.springframework.web.bind.annotation.RestController;
8
9 @RestController
10 public class HelloController {
11
12 @Autowired
13 private HelloService helloServcie;
14
15 @RequestMapping("/test/{fallback}")
16 public String hello(@PathVariable("fallback") String fallback){
17 String res=helloServcie.hello(fallback);
18 return "结果为:"+res;
19 }
20
21 @RequestMapping("/getUserById/{fallback}")
22 public String getUserById(@PathVariable("fallback") String fallback){
23 String userString=helloServcie.getUserById(fallback);
24 System.out.println("==结果：==="+userString);
25 return userString;
26 }
27 }
3.6：启动类MyConsumerApplication
1 package com.tiandy.myconsumer;
2
3 import org.springframework.boot.SpringApplication;
4 import org.springframework.boot.autoconfigure.SpringBootApplication;
5 import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
6 import org.springframework.cloud.netflix.feign.EnableFeignClients;
7 import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
8
9 @SpringBootApplication
10 @EnableEurekaClient
11 @EnableZuulProxy
12 @EnableFeignClients
13 public class MyConsumerApplication {
14
15 public static void main(String[] args) {
16 SpringApplication.run(MyConsumerApplication.class, args);
17 }
18 }
注意：@EnableZuulProxy是开启网关功能的注解
3.7：启动服务，看服务consumer-client是否注册到了注册中心
启动成功后，访问http://127.0.0.1:8761/ 
四：启动服务测试
把cloud-service、my-client、my-consumer三个服务都启动成功后，访问
http://127.0.0.1:8082/test/1
http://127.0.0.1:8082/test/2
http://127.0.0.1:8082/getUserById/101
http://192.168.100.50:8761/techouse/usersystem/getUserById/101
注意：我们可以使用统一入口，调用PRODUCT-CLIENT服务：
访问的url： http://127.0.0.1:8761/techouse/usersystem/hello/2 其中techouse/usersystem是cloud-service项目中zuul配置的网关和路由(perfix和path)
至此,以上便是一个简单完成的SpringCloud微服务架构了！
