Getway实现nacos注册及服务转发

首先创建一个module——kiba-getway，如下图：

我们新建的项目缺少resources文件夹，打开project structure——moudules，右键java，创建文件夹，如下图：

然后选择resources，再点击【mark a directory as a resources root】，设置resource root，如下图：

然后修改pom里的组件版本，文件代码如下：

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                            <goal>repackage</goal>

                </executions>
            </plugin>
        </plugins>
    </build>

</project>

然后在resources下添加bootstrap.yml文件，编写内容如下：

spring:
  application:
    name: kiba-gateway
  cloud:
    nacos:
      discovery:
        server-addr: 10.1.0.145:8848
        username: nacos
        password: nacos
        auto-register: true
        reactive:
          enabled: false #关闭响应式发现服务，不需要返回消息，增加注册速度，简化复杂度
    gateway:
      discovery:
        locator:
          enabled: true #网关能够通过特定的机制发现和使用其他服务。该配置会将其他服务自动根据服务名进行映射
      httpclient:
        max-header-size: 104857600
    loadbalancer:
      retry:
        enabled: true #启动负载均衡重试

上文设置了gateway.discovery.locator.enabled=true。所以会将其他服务自动根据服务名进行映射。

项目结构很简单，如下图：
