SpringBoot集成Eurake、Gateway和Redis+Token验证拦截器实现

SpringBoot聚合项目配置Eurake和Gateway

本文简单说名了Eurake、Gateway和Redis的配置及使用,聚合项目内相关包未做精简规划,Pom配置仅供参考
Redis默认只允许本机IP访问,如果测试时Redis安装地址与项目地址不一致,需要修改Redis配置文件,详细说明参考另一篇Redis安装教程即可

一、版本信息:

  1.  SpringBoot		2.2.6.RELEASE
    
  2.  SpringCloud	Hoxton.SR1
    
  3.  项目目录如图:

二、开始配置一个聚合项目

1.先建一个父级工程:

最终pom.xml配置如下:



	4.0.0
	
		org.springframework.boot
		spring-boot-starter-parent
		2.2.6.RELEASE
		 
	
	com.demo
	zhx-parent
	0.0.1-SNAPSHOT
	zhx-parent
	Demo project for Spring Boot

	
		1.8
	

	
		
			org.springframework.boot
			spring-boot-starter-web
		

		
			org.springframework.boot
			spring-boot-devtools
			runtime
			true
		
		
			org.projectlombok
			lombok
			true
		
		
			org.springframework.boot
			spring-boot-starter-test
			test
			
				
					org.junit.vintage
					junit-vintage-engine
				
			
		
	

	
		
			
				org.springframework.boot
				spring-boot-maven-plugin
			
		
	



2.新建一个Eurake子工程

如图,右键父项目New-Module
SpringBoot集成Eurake、Gateway和Redis+Token验证拦截器实现_第2张图片
Pom文件如下:



	4.0.0
	
		org.springframework.boot
		spring-boot-starter-parent
		2.2.6.RELEASE
		 
	
	com.demo
	zhx-eurake
	0.0.1-SNAPSHOT
	zhx-eurake
	Demo project for Spring Boot

	
		UTF-8
		UTF-8
		1.8
		Hoxton.SR1
	

	
		
		
			org.springframework.cloud
			spring-cloud-starter-netflix-eureka-server
		
		
			org.springframework.boot
			spring-boot-autoconfigure
		
		
			org.springframework.boot
			spring-boot-starter-web
		

		
			org.springframework.boot
			spring-boot-starter-test
			test
			
				
					org.junit.vintage
					junit-vintage-engine
				
			
		
	
	
		
			
				org.springframework.cloud
				spring-cloud-dependencies
				${spring-cloud.version}
				pom
				import
			
		
	
	
		
			
				org.springframework.boot
				spring-boot-maven-plugin
			
		
	
	
		
			spring-milestones
			Spring Milestones
			https://repo.spring.io/milestone
			
				false
			
		
	


配置文件:

server:
  port: 8082 #服务注册中心端口号

spring:
  application:
    name: zhx-eurake

eureka:
  instance:
    hostname: 127.0.0.1 #服务注册中心IP地址
  client:
    registerWithEureka: true #是否向服务注册中心注册自己
    fetchRegistry: false #是否检索服务
    serviceUrl: #服务注册中心的配置内容,指定服务注册中心的位置
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
  server:
    renewal-percent-threshold: 0.5 #留存的服务示例低于多少比例进入保护模式
    enable-self-preservation: true #是否开启保护模式


启动类要加上Eureka注解

package com.demo.eurake;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * 启动一个服务注册中心
 */
@EnableEurekaServer
@SpringBootApplication
public class ZhxEurakeApplication {

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

}

3.再建一个Gateway子工程

Pom文件如下:



	4.0.0
	
		org.springframework.boot
		spring-boot-starter-parent
		2.2.6.RELEASE
		 
	
	com.demo
	zhx-gateway
	0.0.1-SNAPSHOT
	zhx-gateway
	Demo project for Spring Boot

三、测试

1.打开浏览器并访问:http://127.0.0.1:8082/

2.用Gateway转发的路径访问:http://localhost:8081/eurake/

3.用Postman进行登录、退出测试

将zhx存入Authorization

用其他账号退出,鉴权失败:
