從Spring Boot應用程序導出jar並部署到ubuntu服務器

Question

我已經開發了一個spring-boot應用程序，我想將此應用程序部署在ubuntu服務器中，但是當我嘗試導出jar文件並在我的PC中對其進行測試時，它不起作用，這是我的應用程序類

@SpringBootApplication
@EnableScheduling
public class Application extends SpringBootServletInitializer{

     @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(Application.class);
        }

    public static void main(String[] args) {
        // TODO Auto-generated method stub
          SpringApplication.run(Application.class, args);
    }
}

這是我的pom.xml

我將項目導出為帶有Eclipse的Runnable Jar文件，當我嘗試使用java -jar執行時，顯示錯誤

Answer 1

大聲笑，我現在有一個非常相似的問題。

不確定是否有必要，因為如果安裝了很多ide彈簧插件，它們可能會為您完成工作，但是由於我們使用的是maven，所以我很確定您必須使用maven來構建項目，以便做對了。

如果您使用的是eclipse，請嘗試運行方式> Maven build ...>目標：打包 （或僅使用命令行對其進行打包）

至少那是我通常所做的。 但是我在Maven的錯誤和問題上記錄很長，從不真正想花費更多的時間來學習似乎如此...不穩定的東西。（一旦我的所有依賴項在一夜之間損壞了，我不得不重新下載其中的三個修復所有LOC標頭錯誤的時間）因此，如果這對您不起作用，請不要感到驚訝。

這不是一個真正的答案，但是在我有50個代表之前，stackoverflow不會讓我發表評論。
