com.google.api.server.spi.auth.EspAuthenticator沒有找到

Question

我工作的谷歌端點API 2.0，並嘗試使用this

部分文檔的集成火力認證。我遇到了一個奇怪的問題，那就是我添加到pom.xml的依賴項com.google.api.server.spi.auth.EspAuthenticator.class沒有顯示出來。還有其他驗證器可用，例如GoogleJwtAuthenticator和GoogleOAuth2Authenticator，但EspAuthenticator不可用於導入。它不被認可。這是我的pom.xml

請告訴我，如果有什麼問題的pom.xml或有一些正在EspAuthenticator.class不可用其他一些問題。

需要包含Endpoints Framework Auth依賴項。看看這個文檔： https://cloud.google.com/endpoints/docs/frameworks/java/adding-api-management
