本文介绍了如何将Java Gateway与Nacos进行整合，详细讲解了配置步骤，包括POM文件和YML文件的添加。同时，讨论了Gateway的限流策略，提供了配置文件的内容，并进一步探讨了Nacos的自定义分组限流，涉及到配置类的修改以及在provider控制器层面的应用。

1.gateway整合nacos

添加pom文件

    <dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba.csp</groupId>
            <artifactId>sentinel-spring-cloud-gateway-adapter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
    </dependencies>

yml文件

server:
  port: 8180
spring:
  application:
    name: gateway
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true
    nacos:
      discovery:
        server-addr: localhost:8848
management:
  endpoints:
    web:
      exposure:
        include: "*"

2.gateway限流

配置文件

package cn.qf.gateway.config;
