錯誤：由於缺少EmbeddedServletContainerFactory bean而無法啟動EmbeddedWebApplicationContext

Question

我已經創建了一個Spring Boot應用程序，並且在Eclipse IDE中可以正常工作，但是當我嘗試使用maven將其構建為獨立的jar時，它給了我這個錯誤。

我的主要班級：

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);


    }

}

我發現，通過以下兩個命令創建的依賴關系

* mvn clean install    
* mvn clean compile assembly:single

導致具有依賴項的jar，但其中不包含普通jar。 幫助將不勝感激。

錯誤跟蹤：

Answer 1

我有同樣的問題。 我通過添加以下依賴項來解決它：

<properties>
    <jetty.version>9.2.17.v20160517</jetty.version>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
</properties>
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

希望這對您有所幫助（盡管您很久以前就遇到過此問題）。
