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

大家好，又见面了，我是你们的朋友全栈君。

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：

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：

代码语言：javascript复制

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

	</build>

</project>

2.新建一个Eurake子工程

如图，右键父项目New-Module

Pom文件如下：

配置文件：

代码语言：javascript复制

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

代码语言：javascript复制

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

配置文件如下：

代码语言：javascript复制

server:
  port: 8083

spring:
  application:
    name: zhx-license
  redis:
    # Redis数据库索引（默认为0）
    database: 10

      # 连接池中的最小空闲连接
      min-idle: 0
      # 连接超时时间（毫秒）
      timeout: 100

eureka:
  instance:
    prefer-ip-address: true
  client:
    service-url:
      defaultZone: http://localhost:8082/eureka/ #注册中心地址

登录和退出类：

代码语言：javascript复制

package com.license.java.controller.login;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;

@RestController
@RequestMapping("/user")
public class LoginController {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;


    @GetMapping("/Login")
    public String Login(String userName,String password){

        stringRedisTemplate.opsForValue().set(userName,password);

        return "登陆成功";
    }

    @GetMapping("/Logout")
    public String Logout(HttpServletRequest request){

        String token = request.getHeader("Authorization");
        stringRedisTemplate.delete(token);
        return "退出成功";
    }


}

启动类：

代码语言：javascript复制

package com.license.java;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableDiscoveryClient
@SpringBootApplication
public class ZhxLicenseApplication {

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

}

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：

用zhx账号退出，成功并从Redis删除zhx记录：

重复退出，由于登录信息已删除，则返回鉴权失败：
