https://gitee.com/lmf-2021/SpringCloud2024/blob/master/SpringCloud%E7%AC%AC3%E5%AD%A32024.html

2.官方全套示例文档，比较简短，不适合新手，适合熟手复习

https://spring-cloud-alibaba-group.github.io/github-pages/2022/zh-cn/

五·Nacos：服务注册发现、配置管理中心

服务注册发现、配置管理中心；本身就是一个单独的微服务；同时也是所有分布式微服务组件的基础应用

<!--    Springcloud-nacos-服务注册中心整合依赖-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<!--	springcloud-nacos-config-配置中心整合依赖-->
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
<!--Springcloud-bootstrap容器整合依赖，可以使用bootstrap.yml配置文件-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

1.Nacos分阶段引入示例：

https://www.cnblogs.com/crazymakercircle/p/14231815.html

2.Nacos配置yml完整示例与解释：

补充1：Nacos服务跨分组调用

https://blog.csdn.net/m0_56287495/article/details/129240577

六·LoadBalancer：远程服务调用框架、客户端负载均衡工具

远程服务调用框架、客户端负载均衡工具（Nginx是服务端负载均衡工具）；需要依赖服务注册与发现；支持与多种http库集成

<!--        Springcloud-loadbalancer-远程服务调用、负载均衡整合依赖，可以单独使用-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-loadbalancer</artifactId>
</dependency>

https://www.cnblogs.com/itxiaoshen/p/16247702.html

七·Openfeign（推荐）：远程服务调用框架、客户端负载均衡工具

远程服务调用框架、客户端负载均衡工具（Nginx是服务端负载均衡工具）；需要依赖服务注册与发现，内部整合了LoadBalancer负载均衡，可以完全替代LoadBalancer组件

<!--Springcloud-openfeign-远程服务调用、负载均衡整合依赖，底层整合loadbalancer，因此需要该依赖-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
<!--        Springcloud-loadbalancer-远程服务调用、负载均衡整合依赖，可以单独使用-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-loadbalancer</artifactId>
</dependency><!-- 根据需要是否添加下面依赖，用于替换Openfeign底层的http请求为请求连接池-->
<!-- httpclient5-->
<dependency><groupId>org.apache.httpcomponents.client5</groupId><artifactId>httpclient5</artifactId>
</dependency>
<!-- feign-hc5-整合依赖-->
<dependency><groupId>io.github.openfeign</groupId><artifactId>feign-hc5</artifactId>
</dependency>

补充1：Openfeign各种属性配置官方文档

https://docs.spring.io/spring-cloud-openfeign/docs/current/reference/html/appendix.html

八·Gateway：微服务端网关路由

微服务端网关路由；本身就是一个单独的微服务；需要依赖服务注册与发现；Gateway服务配置路由之后，再访问Gateway服务，Gateway服务就可以把请求转发到其他具体微服务上面；

<!--        网关是响应式编程，必须删除掉 spring-boot-starter-web 场景dependency-->
<!--        Springcloud-gateway-网关路由整合依赖-->
<dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-gateway</artifactId>
</dependency><!--        根据需要添加：解决netty框架与mac系统m1芯片集成dns问题-->
<dependency><groupId>io.netty</groupId><artifactId>netty-resolver-dns-native-macos</artifactId>
<!--            <version>4.1.75.Final</version> &lt;!&ndash;版本号自己切&ndash;&gt;--><classifier>osx-aarch_64</classifier>
</dependency>

3.官方中文文档-最新版：

https://springdoc.cn/spring-cloud-gateway/#setrequestheader

补充1：Nginx网关与Gateway网关区分：

一般情况：将Nginx设置为流量网关，Gateway设置为业务网关，两者作用都是负载均衡作用，Gateway网关细腻度更低

https://developer.aliyun.com/article/1002990#slide-3

九·Sentinel：服务流量治理组件

服务流量治理组件；本身就是一个单独的微服务；A微服务配置注册到Sentinel服务之后，访问A微服务接口，请求的流量就会被Sentinel服务监控到

<!--	SpringCloud alibaba sentinel 服务流量治理组件-->
<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
</dependency>
