SpringBoot聚合項目配置Eurake和Gateway

本文簡單說名了Eurake、Gateway和Redis的配置及使用，聚合項目內相關包未做精簡規劃，Pom配置僅供參考
Redis默認只允許本機IP訪問，如果測試時Redis安裝地址與項目地址不一致，需要修改Redis配置文件，詳細說明參考另一篇Redis安裝教程即可

一、版本信息：

 SpringBoot		<version>2.2.6.RELEASE</version>

 SpringCloud	<spring-cloud.version>Hoxton.SR1</spring-cloud.version>

二、開始配置一個聚合項目

1.先建一個父級工程：

最終pom.xml配置如下：

<?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">
	<modelVersion>4.0.0</modelVersion>
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.2.6.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.demo</groupId>
	<artifactId>zhx-parent</artifactId>
	<version>0.0.1-SNAPSHOT</version>

			<plugin>

				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

</project>

2.新建一個Eurake子工程

如圖，右鍵父項目New-Module

Pom文件如下：

<?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"

		</repository>
	</repositories>
</project>

配置文件：

server:
  port: 8082 #服務註冊中心端口號

spring:
  application:
    name: zhx-eurake

eureka:
  instance:
    hostname: 127.0.0.1 #服務註冊中心IP地址
  client:
    registerWithEureka: true #是否向服務註冊中心註冊自己
    fetchRegistry: false #是否檢索服務
    serviceUrl: #服務註冊中心的配置內容，指定服務註冊中心的位置
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
  server:
    renewal-percent-threshold: 0.5 #留存的服務示例低於多少比例進入保護模式
    enable-self-preservation: true #是否開啓保護模式

啓動類要加上Eureka註解

package com.demo.eurake;

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

/**
 * 啓動一個服務註冊中心
 */
@EnableEurekaServer
@SpringBootApplication
public class ZhxEurakeApplication {

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

}

3.再建一個Gateway子工程

Pom文件如下：

4.增加一個登陸模塊![在這裏插入圖片描述](https://img-blog.csdnimg.cn/2020050622054755.png?x-oss-

配置文件如下：

server:

spring:
  application:
    name: zhx-license
  redis:
    # Redis數據庫索引（默認爲0）
    database: 10

      timeout: 100

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

登錄和退出類：

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 "登陸成功";
    }

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

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


}

啓動類：

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、測試

1.打開瀏覽器並訪問：http://127.0.0.1:8082/

2.用Gateway轉發的路徑訪問：http://localhost:8081/eurake/

3.用Postman進行登錄、退出測試

將zhx存入Authorization

用其他賬號退出，鑑權失敗：

用zhx賬號退出，成功並從Redis刪除zhx記錄：

重複退出，由於登錄信息已刪除，則返回鑑權失敗：

SpringBoot集成Eurake、Gateway和Redis+Token驗證攔截器實現

一、版本信息：

二、開始配置一個聚合項目

三、測試
