Spring Cloud中怎么實現(xiàn)zuul網(wǎng)關(guān)服務(wù)，針對這個問題，這篇文章詳細(xì)介紹了相對應(yīng)的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。

# 目標(biāo)主機(jī)的最大連接數(shù)，默認(rèn)值為200

# 所有路由的默認(rèn)Hystrix隔離模式（ExecutionIsolationStrategy）為SEMAPHORE。如果此隔離模式是首選，則zuul.ribbonIsolationStrategy可以更改為THREAD
ribbon-isolation-strategy: thread
# 這個屬性意思，指定忽略的服務(wù)列表 * 代表忽略所有服務(wù)
ignored-services: '*'
# 字段比較敏感，不希望傳遞給下游微服務(wù)。 設(shè)置空沒有要忽略的敏感字段。全部傳給下游服務(wù)
sensitive-headers: X-ABC
ribbon:
eager-load:
# 強制加載，不設(shè)置會進(jìn)行懶加載。spring 第一次請求會非常慢
enabled: true
```
#### 參數(shù)
- zuul.host.max-total-connections 目標(biāo)主機(jī)的最大連接數(shù)。
- zuul.host.max-per-route-connections 每個主機(jī)的初始連接數(shù)。
這個倆個參數(shù)是zuul的優(yōu)化后的屬性值，如果想有適合的配置，還需要根據(jù)業(yè)務(wù)情況而定
因為我們有倆個業(yè)務(wù)服務(wù) 一個服務(wù)提供者 一個是服務(wù)消費者我們配置倆個服務(wù)的分別路由 discovery-server、client-common
- path 是請求路徑匹配規(guī)則
- serviceId 是我們服務(wù)的spring.application.name 對應(yīng)的值。
- sensitiveHeaders 字段比較敏感，不希望傳遞給下游微服務(wù)。 設(shè)置空沒有要忽略的敏感字段。全部傳給下游服務(wù)這個字段可以是全局設(shè)置也可以是單個服務(wù)配置。
- ribbon-isolation-strategy 所有路由的默認(rèn)Hystrix隔離模式（ExecutionIsolationStrategy）為SEMAPHORE。如果此隔離模式是首選，則zuul.ribbonIsolationStrategy可以更改為THREAD
- ignored-services 忽略所有微服務(wù)，只路由指定的微服務(wù)。
- ribbon.eager-load.enabled true 強制加載 false 默認(rèn)懶加載
true日志打印效果 false 將不打印這段日志

將三個服務(wù)全部啟動。服務(wù)提供者和服務(wù)消費者還有zuul 服務(wù)
在控制臺 輸入命令 curl http://localhost:9083/client/client/test
我們看到打印效果，請求通過網(wǎng)關(guān)服務(wù)成功轉(zhuǎn)發(fā)到了我們的下游服務(wù)上。并返回
- ribbon-isolation-strategy
- ignored-services
