springcloud搭建（十三）Zuul API路由網關

1.創建microservice-zuul-3001項目並添加依賴

<dependency>
    <groupId>com.java1234.springcloud</groupId>
    <artifactId>microservice-common</artifactId>
    <version>${project.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- zuul路由網關 -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zuul</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<!-- actuator監控 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<!-- hystrix容錯 -->

</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>

<!-- 修改後立即生效，熱部署 -->

2.application.yml

server:
  port: 3001
  context-path: /

spring:
  application:
    name: microservice-zuul

eureka:
  instance:
    instance-id: microservice-zuul:3001 #客戶端實例名稱
    prefer-ip-address: true #顯示IP
  client: 
    service-url: 
      defaultZone: http://eureka2001.java1234.com:2001/eureka/,http://eureka2002.java1234.com:2002/eureka/,http://eureka2003.java1234.com:2003/eureka/ # 集羣

3.啓動類

package com.java1234;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
 
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
@EnableZuulProxy
public class ZuulApplication_3001 {
 
    public static void main(String[] args) {
        SpringApplication.run(ZuulApplication_3001.class, args);
    }
     
}

 4.啓動三個eureka，一個服務提供者，一個zuul，請求地址：zuul.java1234.com:3001/microservice-student/student/list，其中zuul.java1234.com爲訪問域名，需要自行配置
