使用步骤
1、引入依赖 spring-cloud-starter-netflix-zuul
2、使用注解 @EnableZuulProxy
3、配置 yml
4、测试：访问zuul所在的IP:端口号 + 你需要的服务名 + 你需要的路由地址来实现

# bootstrap.yml spring: application: name: api-gateway cloud: config: discovery: enabled: true service-id: CONFIG profile: dev eureka: client: service-url: defaultZone: http://localhost:8761/eureka/ zuul: routes: # 自定义路由地址 # /myProduct/product/list -> /product/product/list aaaaaa: path: /myProduct/** serviceId: product # sensitiveHeaders是敏感头的配置，如果需要传递敏感信息如cookie，将其设置为空。默认是过滤掉 cookie，解除过滤 cookie sensitiveHeaders: # 简洁写法 # product: /myProduct/** # 排除某些路由（路由禁用配置套路，支持通配符） ignored-patterns: - /**/product/listForOrder management: security: enabled: false
查看所有路由规则，首先需要配置：management.security.enabled: false（查看路由权限打开）
较新版本的配置：
# 新版本中management.security.enabled配置已经过时，改用下面的配置
# 放开请求路径，这样才能在启动日志里面看到隐藏的请求 management.endpoints.web.exposure.include=*
# 新版本查看routes规则，不再是application/routes 而是/actuator/routes
package com.imooc.apigateway; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.cloud.context.config.annotation.RefreshScope; import org.springframework.cloud.netflix.zuul.filters.ZuulProperties; import org.springframework.stereotype.Component; @Component public class ZuulConfig { @ConfigurationProperties("zuul") @RefreshScope public ZuulProperties zuulProperties() { return new ZuulProperties(); } }
或
package com.imooc.apigateway; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.zuul.EnableZuulProxy; @SpringBootApplication @EnableZuulProxy public class ApiGatewayApplication { public static void main(String[] args) { SpringApplication.run(ApiGatewayApplication.class, args); } @ConfigurationProperties("zuul") @RefreshScope public ZuulProperties zuulProperties() { return new ZuulProperties(); } }
- 这样配置后再到 git 上配置对应的，就可以实现自动刷新啦！
