Spring Cloud Gateway
Spring Cloud Gateway 筆記
Spring Cloud Gateway 簡介
Spring生態系統之上構建的API網關，包括：Spring 5，Spring Boot 2和Project Reactor。Spring Cloud Gateway旨在提供一種簡單而有效的方法來路由到API，並基於Filter 提供 gateway的基本功能，例如：安全性，監視/指標和彈性。
Spring Cloud Gateway 監控
添加依賴 - build.gradle
implementation 'org.springframework.cloud:spring-cloud-starter-gateway'
implementation 'org.springframework.boot:spring-boot-starter-actuator'
implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
配置文件 - application.properties OR application.yml
該/gateway驅動器的端點允許監視和使用Spring的雲網關應用程序進行交互。為了可遠程訪問，必須在應用程序屬性中通過HTTP或JMX啟用和公開端點。
application.properties
# default value
management.endpoint.gateway.enabled=true
management.endpoints.web.exposure.include=gateway
application.yml
management:
endpoint:
gateway:
enabled: true
endpoints:
web:
exposure:
include: gateway
得到所有route的資訊
{IP}/actuator/gateway/routes
[
{
"predicate": "Paths: [/hollword/**], match trailing slash: true",
"route_id": "holl-word",
"filters": [],
"uri": "lb://holl-word",
"order": 0
},
{
"predicate": "Paths: [/hollJava/**], match trailing slash: true",
"route_id": "holl-Java",
"filters": [],
"uri": "lb://holl-Java",
"order": 0
}
]
| Path | Type | Description |
|---|---|---|
route_id | String | The route id. 路由代號 |
route_object.predicate | Object | The route predicate. |
route_object.filters | Array | The GatewayFilter factories applied to the route. 過濾器 |
order | Number | The route order. 路線順序 |
得到某個route的資訊
{IP}/actuator/gateway/routes/{id}
{
"predicate": "Paths: [/wealth/**], match trailing slash: true",
"route_id": "wealth",
"filters": [],
"uri": "lb://wealth-system",
"order": 0
}
所有Gateway actuator可以用的列表
/actuator/gateway/{ID}
| ID | HTTP Method | Description |
|---|---|---|
| globalfilters | GET | Displays the list of global filters applied to the routes. |
| routefilters | GET | Displays the list of GatewayFilter factories applied to a particular route. |
| refresh | POST | Clears the routes cache. |
| routes | GET | Displays the list of routes defined in the gateway. |
| routes/{id} | GET | Displays information about a particular route. |
