############Zuul简单使用################

1、pom.xml

            </plugin>

        </plugins>

    </build>

</project>

2、添加注解

package com.test.eurekaclientfeign;

import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.web.servlet.ServletRegistrationBean;

import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;

import org.springframework.cloud.netflix.hystrix.EnableHystrix;

import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

import org.springframework.cloud.openfeign.EnableFeignClients;

import org.springframework.context.annotation.Bean;

@SpringBootApplication

@EnableFeignClients

@EnableCircuitBreaker

@EnableHystrixDashboard

@EnableHystrix

@EnableZuulProxy

public class EurekaClientFeignHystrixZuulApplication {

    public static void main(String[] args) {

        SpringApplication.run(EurekaClientFeignHystrixZuulApplication.class, args);

    }

    @Bean

    public ServletRegistrationBean getServlet(){

        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();

        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);

        registrationBean.setLoadOnStartup(1);

        registrationBean.addUrlMappings("/actuator/hystrix.stream");

        registrationBean.setName("HystrixMetricsStreamServlet");

        return registrationBean;

    }

}

3、application.yml配置文件

spring:

  application:

    name: eureka-client-feign-hystrix-zuul  #应用名

logging:  #logging日志配置

  level:

    root: INFO

    org.hibernate: INFO

server:

  port: 8669   #服务端口

eureka:

  instance:

    hostname: localhost

    prefer-ip-address: true

    instance-id: ${spring.application.name}:${spring.application.instance_id:${server.port}}

  client:

    serviceUrl:

      defaultZone: http://${eureka.instance.hostname}:8661/eureka

management:

  endpoints:

    web:

      exposure:

        include: '*'

  endpoint:

    health:

      show-details: always

这样就完成了，只是这种方式访问，需要添加serviceID访问

例如：

#不使用Zuul访问

http://192.168.137.1:8664/user/1

#使用Zuul访问,其中eureka-client-user为serviceId

http://192.168.137.1:8669/eureka-client-user/user/4

###############自己配置Zuul##################

在application.yml添加如下的配置

spring:

                      application:

                        name: eureka-client-feign-hystrix-zuul  #应用名

                      logging:  #logging日志配置

                        level:

                          root: INFO

                          org.hibernate: INFO

                      server:

                        port: 8669   #服务端口

                      eureka:

                        instance:

                          hostname: localhost

                          prefer-ip-address: true

                          instance-id: ${spring.application.name}:${spring.application.instance_id:${server.port}}

                        client:

                          serviceUrl:

                            defaultZone: http://${eureka.instance.hostname}:8661/eureka

                      management:

                        endpoints:

                          web:

                            exposure:

                              include: '*'

                        endpoint:

                          health:

                            show-details: always

zuul:

  routes:

    eureka-client-user: /myuser/**  #将serviceID = eureka-client-user 简化为 /myuser
