2-13-Gateway网关-快速入门

搭建网关

1.新建springboot项目

2.将新建项目作为模块加入原有体系

            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>

            <scope>test</scope>
        </dependency>

        <!--网关-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>

        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

3.配置nacos相关信息便于服务注册发现

server:
  port: 10088
spring:
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
        cluster-name: HZ
  application:
    name: mygateway

网关路由

1.配置服务路由

注意:当路由有多个的时候 可能会出现异常 原因暂时未知 但是应该可以通过一个微服务一个前缀来实现隔离

spring:
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
        cluster-name: HZ
    gateway:
      routes:
        - id: userservice
          uri: lb://userservice
          predicates:
            - Path=/user/**
        - id: orderservice
          uri: lb://orderservice
          predicates:
#            - Path=/order/**
            - Path=/feignOrder/**
#            - Path=/restOrder/**
