            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>

        <!--项目基础依赖-->

2、添加hystrix 熔断器配置、Ribbon 程序入口和服务消费者实现Controller

package com.zzg.config;

import com.netflix.loadbalancer.IRule;
import com.netflix.loadbalancer.RandomRule;
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 RibbonConfig {
    @Bean
    @LoadBalanced //负载均衡标识
    RestTemplate restTemplate() {
        return new RestTemplate();
    }
}

package com.zzg.controller;

import com.zzg.model.User;
import com.zzg.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/list")
    public List<User> get() {
        List<User> list = userService.selectAll();
        return list;
    }
}

package com.zzg.service;

import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;
import com.zzg.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;

import java.util.List;


@Service
public class UserServiceImpl implements  UserService {
    @Autowired
    RestTemplate template;

    @Override
    @HystrixCommand(fallbackMethod = "ServiceError")
    public List<User> selectAll() {
        String url ="http://provider1/provider/list";
        return template.getForObject(url, List.class);
    }

    public List<User> ServiceError() {
        System.out.println("熔断机制启动, Provider 服务提供者异常");
        return null;
    }

}

package com.zzg;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.hystrix.EnableHystrix;

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

3、添加application.properties 配置文件?

server.port=8085
server.servlet.context-path=/consumer-ribbon
spring.application.name=consumer-ribbon
eureka.client.service-url.defaultZone=http://127.0.0.1:8081/eureka/

smart-medical-consumer-feign 基于Feign 服务消费者

1、项目结构截图：

2、pom.xml 文件添加? 添加eureka 客户端jar 包依赖、hystrix 熔断器jar包依赖和智慧医疗通用模块依赖

        </dependency>
    </dependencies>

</project>

2、添加hystrix 熔断器配置、Feign程序入口和服务消费者实现Controller

package com.zzg.controller;

import com.zzg.model.User;
import com.zzg.service.UserServiceFeign;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
public class UserFeignController {
    @Autowired
    UserServiceFeign userServiceFeign;

    @RequestMapping(value = "/list")
    public List<User> selectAll() {
        return userServiceFeign.selectAll();
    }

}

package com.zzg.hystric;

import com.zzg.model.User;
import com.zzg.service.UserServiceFeign;
import org.springframework.stereotype.Component;

import java.util.List;

@Component
public class UserServiceHystric implements UserServiceFeign {
    @Override
    public List<User> selectAll() {
        System.out.println("熔断机制启动, Provider 服务提供者异常");
        return null;
    }
}

package com.zzg.service;

import com.zzg.hystric.UserServiceHystric;
import com.zzg.model.User;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.GetMapping;

import java.util.List;

@FeignClient(value = "provider1",fallback = UserServiceHystric.class)
@Service
public interface UserServiceFeign {
    @GetMapping("/provider/list")
    List<User> selectAll();
}

package com.zzg;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.openfeign.EnableFeignClients;

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

3、添加application.properties 配置文件?

server.port=8086
spring.application.name=consumer-feign
eureka.client.service-url.defaultZone=http://127.0.0.1:8081/eureka/
# ??????
feign.hystrix.enabled=true

smart-medical-zuul 网关服务

1、项目截图：

2、添加zuul 网关服务程序入口

package com.zzg;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

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

3、添加application.properties 配置文件

server.port=8087
