無法啓動jHipster微服務網關開箱即用

Question

所以我建立了一個開箱即用的jHipster微服務網關。我有jHipster 4.5.2。除了回答設置問題之外，我沒有做任何事情（你可以在下面看到我的答案）。我分配它在localhost：8082上運行。我也安裝了可以工作的Tomcat 8.5.15;當我打開它時，我在localhost：8080上看到服務器頁面。

我曾嘗試做運行網關如下：

/Users/jimstewart/apache-maven-3.3.9/bin/mvn -Pprod package 
java -jar target/data-gateway-0.0.1-SNAPSHOT.war 

當它試圖啓動，我得到以下警告早就：

Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/DataGateway/dev/master": Connection refused; nested exception is java.net.ConnectExc 

但Tomcat服務器正在運行：當我去localhost：8080頁面在那裏。

有大量的樣板，數百行，所以我不會複製它們。但在以下錯誤中繼續重複

2017-06-03 22:48:58.671 ERROR 1271 --- [   main] c.n.d.s.t.d.RedirectingEurekaHttpClient : Request execution error 

2017-06-03 22:48:58.674 WARN 1271 --- [   main]

message: java.net.ConnectException: Connection refused 

2017-06-03 22:48:58.675 ERROR 1271 --- [   main]

c.n.d.s.t.d.RetryableEurekaHttpClient : Request execution failed with message: java.net.ConnectException: Connection refused 

最終它只是關閉而不開始。

我也嘗試通過從NetBeans運行它來啓動它。當我打開Tomcat時，它會退出，因爲「無法啓動Tomcat：端口8080已被使用。」所以，很好，在Tomcat關閉的情況下啓動它，這樣它就可以打開它。然後它不會啓動，因爲「連接被拒絕」。

如何讓我的應用程序啓動？

Answer 1

在此處顯示的錯誤：

Could not locate PropertySource: I/O error on GET request for "http://localhost:8761/config/DataGateway/dev/master": Connection refused; nested exception is java.net.ConnectExc

這意味着你沒有啓動JHipster登記。 對於這一點，你有2個解決方案：

1）泊塢窗，只需啓動：docker-compose -f src/main/docker/jhipster-registry.yml up -d

2）克隆項目https://github.com/jhipster/jhipster-registry，然後yarn install並啓動註冊表：./mvwn

然後，嘗試登錄成http://localhost:8761

PS：我因爲您的網關已經使用嵌入式Undertow，所以不太瞭解您在這裏如何使用Tomcat，因此您不需要另一臺服務器。
