前言：

        本文使用springboot版本2.3.7，springCloud:Hoxton.SR9,springCloudAlibaba:2.2.6.RELEASE,使用时候需要注意版本搭配，否则可能出现奇怪问题

搭建步骤

1、使用idea搭建一个空白项目gateway

2、POM引入下面依赖

 <properties><java.version>11</java.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><spring-boot.version>2.3.7.RELEASE</spring-boot.version><spring-cloud.version>Hoxton.SR9</spring-cloud.version><spring-cloud-alibaba.version>2.2.6.RELEASE</spring-cloud-alibaba.version></properties><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter</artifactId></dependency><!--gateway网关--><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-gateway</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><!--nacos服务器注册发现--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId></dependency><!--nacos配置中心--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><scope>provided</scope></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>${spring-boot.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${spring-cloud-alibaba.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>

3、启动本地nacos

        ncaos可以是windows本地的或者linux的都可以，我这里使用本地nacos，启动后访问loalhost:8848 目前是没有服务的

4、添加启动类注解和nacos注册以及配置信息

        gateway启动类添加 @EnableDiscoveryClient 注解，亲测不添加也可以

        配置nacos注册中心地址，application.yml添加如下内容：

spring:cloud:nacos:discovery:server-addr: 127.0.0.1:8848

     配置nacos配置中心，在bootstrap.yml中添加如下内容，如果没有这个文件也可以直接在上面application.yml中添加。

spring:application:name: gatewaycloud:nacos:discovery:enabled: trueservice: ${spring.application.name}config:enabled: trueencode: UTF-8file-extension: yml

 5、在nacos中配置gateway的内容，方便实时更新，内容如下：

spring:cloud:gateway:routes:- id: baiduuri: https://www.baidu.compredicates:- Path=/- id: user-service-loginuri: lb://user-servicepredicates:- Path=/user-service/user/loginfilters:- StripPrefix=1
#            - PrefixPath=/- id: user-service-infouri: lb://user-servicepredicates:- Path=/user-service/user/infofilters:- StripPrefix=1- Auth

6、启动相关，观察nacos服务列表是否有gateway注册成功

出现如上图说明启动注册成功，可以访问网关配置观察路由配置是否成功
