- 下载安装 可以参考 springcloud 整合新版本seata、nacos
- 注意事项：
springcloud 整合新版本seata、nacos，如果只整合 nacos,则只需要参考nacos 配置。有关 seata的不用管
如果没有修改 startup.cmd 的 MODE值（set MODE=“standalone”），在单机的情况下，会出现：

因为 nacos 默认是集群环境， 如果是本机开发使用的情况下，则需要更改 moded
springcloud整合 nacos 的注册，并通过网关访问- 版本要求： spring-cloud-dependencies Hoxton.SR9； spring-cloud-alibaba-dependencies 2.2.6.RELEASE； spring-boot-starter-parent 2.3.2.RELEASE；整合的时间版本如果不一致，则会出现各种各样的奇怪问题
- 新建父项目： parent, pom文件：
4.0.0 org.springframework.boot spring-boot-starter-parent 2.3.2.RELEASE com.example parent 0.0.1 parent 父项目 pom gateway project 1.8 org.springframework.cloud spring-cloud-dependencies Hoxton.SR9 pom import com.alibaba.cloud spring-cloud-alibaba-dependencies 2.2.6.RELEASE pom import org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-maven-plugin
- 新建 gateway 子服务： pom文件：
4.0.0 com.example parent 0.0.1 com.example gateway 0.0.1 gateway 网关 1.8 com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery org.springframework.cloud spring-cloud-starter-gateway org.springframework.boot spring-boot-maven-plugin
配置文件为： application.yml
server:
port: 8001
spring:
application:
name: gateway
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
gateway:
routes:
# 认证中心
- id: project
uri: lb://project
predicates:
- Path=/project
@RestController
@RequestMapping("/testController")
@Slf4j
public class TestController {
@GetMapping("/test")
public String test(){
String str = "project 开始测试代码";
log.info(str);
return str;
}
@PostMapping("/test02")
public String test02(){
String str = "project 开始测试代码";
log.info(str);
return str;
}
}
新建完服务之后的目录结构
- 启动 nacos, 和gateway project这两个服务
则说明这两个服务已经注册成功 - 访问 http://localhost:8001/project/testController/test ， 测试之
出现此图，则说明测试成功
- 引入 gateway 依赖：
org.springframework.cloud
spring-cloud-starter-gateway
引入nacos依赖注册：
com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery
- 在gateway 服务中，如果依赖中有spring-boot-starter-web，则会出现一下异常
org.springframework.boot spring-boot-starter-web
Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. Please remove spring-boot-starter-web dependency.
