39.SpringCloud—配置管理nacos、远程调用Feign、服务网关Gateway
在Spring Cloud中,使用Nacos作为配置管理和服务注册中心,Feign用于远程调用服务,Spring Cloud Gateway作为服务网关,可以配置路由规则,以下是简化的示例代码:
- 引入相关依赖(
pom.xml
):
<dependencies>
<!-- Spring Cloud Alibaba Nacos -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<!-- Spring Cloud OpenFeign -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
<!-- Spring Cloud Gateway -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
</dependencies>
- Nacos配置管理(
bootstrap.properties
):
spring.application.name=my-service
spring.cloud.nacos.config.server-addr=127.0.0.1:8848
spring.cloud.nacos.config.namespace=your-namespace
spring.cloud.nacos.config.group=DEFAULT_GROUP
spring.cloud.nacos.config.extension-configs[0].data-id=my-service-dev.properties
spring.cloud.nacos.config.extension-configs[0].group=DEFAULT_GROUP
spring.cloud.nacos.config.extension-configs[0].refresh=true
- 使用Feign进行远程服务调用(
FeignClient
):
@FeignClient(name = "other-service", url = "http://other-service-host:port")
public interface OtherServiceClient {
@GetMapping("/api/resource")
String getResource();
}
- 服务网关配置(
application.yml
):
spring:
cloud:
gateway:
routes:
- id: other_service_route
uri: lb://other-service
