Spring Boot 集成 Apollo 報 [Cause: [status code: 404] Could not find config for namespace

Spring Boot 集成 Apollo 報以下異常：

10:11:21.891 [main] WARN  c.c.f.a.i.RemoteConfigRepository - Load config failed, will retry in 1 SECONDS. appId: 201909261015778899, cluster: platform-tw, namespaces: application

開始有點奇怪，我在項目中並未使用application命名空間，application.properties配置以下：

# 應用全局惟一的身份標識
app.id = 20190926778899
# Apollo Meta Server 地址
apollo.meta = http://127.0.0.1:8011
# 自定義本地配置文件緩存路徑
# apollo.cacheDir = ./config
apollo.cluster = platform-tw
# 設置在應用啓動階段就加載 Apollo 配置
apollo.bootstrap.enabled = true
# 注入 application namespace
apollo.bootstrap.namespaces = redis

經查看源碼，開啓阿波羅配置註解@EnableApolloConfig()，默認命名空間爲application，此處需注入命名空間爲redis屬性配置，天然會出現不能加載異常，正常作法爲把註解修改成：@EnableApolloConfig(value = {"redis"})
