springcloud 中gateway的搭建

1. 创建maven工程添加pom依赖

   <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>2.3.7.RELEASE</version>
   </parent>
   <!--  还需要添加springcloud依赖  -->
   <dependencyManagement>
       <dependencies>
           <!--      springcloud      -->
           <dependency>
               <groupId>org.springframework.cloud</groupId>
               <artifactId>spring-cloud-dependencies</artifactId>
               <version>${springcloud.version}</version>
               <type>pom</type>
               <scope>import</scope>
           </dependency>
       </dependencies>
   </dependencyManagement>
   
   <dependencies>
       <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-gateway</artifactId>
       </dependency>
       <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
       </dependency>
   </dependencies>
   <build>
       <plugins>
           <plugin>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-maven-plugin</artifactId>
           </plugin>
       </plugins>
   </build>
   
   

2. 修改启动类

   @SpringBootApplication
   @EnableEurekaClient
   public class GatewayApplication {
       public static void main(String[] args) {
           SpringApplication.run(GatewayApplication.class, args);
       }
   }
   
   

3. 创建Resources 资源目录，创建application.yml文件，并添加如下配置

   server:
     port: 7004
   spring:
     application:
       name: gateway
     cloud:
       gateway:
         globalcors:
           cors-configurations:
             '[/**]': # 匹配所有请求
               allowCredentials: true
               allowedOrigins: "*" # 支持跨域，允许所有的域
               allowedMethods: "*" # 支持的方法,允许所有的方法
               allowedHeaders: "*"
         discovery:
           locator:
             enabled: true
         routes:
           - id: CLIENT01
             uri: lb://CLIENT01
             predicates:
               - Path=/CLIENT01/user/**
             filters:
               - StripPrefix=1
   eureka:
     client:
       service-url:
         defaultZone: http://127.0.0.1:7001/eureka
     instance:
       prefer-ip-address: true
   
   

4. 启动eureka启动gateway即可
