SpringCloud zuul简单路由实现

SpringCloudZuul

• 创建各微服务（eureka，producer，zuul）
• producer简单的接口提供，返回string
• zuul 网关服务配置

1. pom

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-zuul</artifactId>
</dependency>

1. application.properties配置

spring.application.name= service-zuul
server.port= 9300
eureka.client.serviceUrl.defaultZone= http://localhost:9000/eureka
#service-producer 为需调用服务名称，有几个配置几个
zuul.routes.service-producer.path=/service-producer/**
zuul.routes.service-producer.serviceId=service-producer

1. ZuulFilter配置

public class ZuulDebugFilter extends ZuulFilter {

private static final Logger LOGGER = LoggerFactory.getLogger(ZuulDebugFilter.class);

@Override
public String filterType() {return "post";}

@Override
public int filterOrder() {return 999;}

@Override
public boolean shouldFilter() {return true;}

@Override
public Object run() {
RequestContext ctx = RequestContext.getCurrentContext();
HttpServletRequest request = ctx.getRequest();
LOGGER.info(String.format("URL: %s", request.getRequestURL().toString()));
return null;
}

• 启动测试
  浏览器访问zuul 服务，zuul实现服务转发
  http://127.0.0.1:9300/service-producer/test?name=username
