使用spring-cloud与zuul实现网关反向代理服务demo_spring

1.首先，我们的项目是springboot项目，所以我们必须引入spring-boot-starter-parent
2.另外，我们的项目是web项目，因此引入spring-boot-starter-web

2.2.创建服务类

package com.gaoxinfu.demo.spring.cloud.zuul;

import org.springframework.web.bind.annotation.*;

/**
 * @Description:
 * @Author: gaoxinfu
 * @Date: 2020-10-23 16:16
 */
@RestController
public class HelloController {

    @RequestMapping(value = "/say/{message}",method = RequestMethod.GET)
    @ResponseBody
    public String say(@PathVariable String message){
        return "HelloController.say = "+message;
    }
}

2.3.配置文件:application.yml

server:
  port: 8080
spring:
  application:
    name: zuul-bussiness

1.服务的端口是8080，项目名称zuul-bussiness

2.4.创建启动类

package com.gaoxinfu.demo.spring.cloud.zuul;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @Description:
 * @Author: gaoxinfu
 * @Date: 2020-10-23 16:13
 */
@SpringBootApplication
public class ZuulBussinessApp {

    public static void main(String[] args) {
        SpringApplication.run(ZuulBussinessApp.class,args);
    }
}

2.6.启动验证

​​http://127.0.0.1:8080/say/hello​​

3.创建一个zuul网关：demo-spring-cloud-zuul-gateway

使用spring-cloud与zuul实现网关反向代理服务demo_maven_03

1.由于我们这里需要使用zuul进行网关的代理路由配置，所以我们引入了spring-cloud-starter-netflix-zuul

3.2.配置文件:application.yml

server:
  port: 8079
spring:
  application:
    name: zuul-gateway


#zuul related configuration
zuul:
  routes:
    zuul-bussiness:
      url: http://localhost:8080

ribbon:
  eureka:
    enabled=false:

1.zuul网关项目的端口8079

使用spring-cloud与zuul实现网关反向代理服务demo_spring_04

3.3.创建Filter过滤器：SimpleFilter

package com.gaoxinfu.demo.spring.cloud.zuul;

import javax.servlet.http.HttpServletRequest;
import com.netflix.zuul.context.RequestContext;
import com.netflix.zuul.ZuulFilter;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


/**
 * @Description:
 * @Author: gaoxinfu
 * @Date: 2020-10-23 15:56
 */
public class SimpleFilter extends ZuulFilter {

    private static Logger log = LoggerFactory.getLogger(SimpleFilter.class);

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

    @Override
    public int filterOrder() {
        return 1;
    }

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

    @Override
    public Object run() {
        RequestContext ctx = RequestContext.getCurrentContext();
        HttpServletRequest request = ctx.getRequest();

        log.info(String.format("%s request to %s", request.getMethod(), request.getRequestURL().toString()));

        return null;
    }

}

3.3.1.filterType

filterType

描述

pre

filters run before the request is routed.

route

filters can handle the actual routing of the request.

post

filters run after the request has been routed.

error

filters run if an error occurs in the course of handling the request.

3.4.创建启动类:NacosZuulGatewayApp

package com.gaoxinfu.demo.spring.cloud.zuul;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.context.annotation.Bean;

/**
 * @Description:
 * @Author: gaoxinfu
 * @Date: 2020-10-23 15:41
 */
@SpringBootApplication
@EnableZuulProxy
public class NacosZuulGatewayApp {

    public static void main(String[] args) {
        SpringApplication.run(NacosZuulGatewayApp.class,args);
    }


    /**
     * 应用启动的时候，我们将SimpleFilter注册到Spring容器之中
     * @return
     */
    @Bean
    public SimpleFilter simpleFilter(){
        return new SimpleFilter();
    }
}

3.5.验证
