无法在IntelliJ Idea中启动spring-boot应用程序

Question

总览

我可以使用spring-boot的maven插件运行该应用程序，但不能在IDE中运行它。以下几行提供有关我的程序的一些详细信息。

应用程序类如下：

package com.blss.retailServices.dataExportRouter;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.velocity.VelocityAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude = { VelocityAutoConfiguration.class })
public class DataExportRouterApplication {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(DataExportRouterApplication.class, args);
    }
}

异常堆栈跟踪如下：

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

我使用@SpringbootApplication但无济于事。

因此，如果有人可以帮助我解决此问题，我将不胜感激。

Answer 1

我猜想您有一个war与Maven一起打包的项目，并且已标记了所提供的servlet引擎（tomcat）。

不幸的是，IntellIJIDEA并未在运行时类路径中添加provided依赖项，这就是为什么从IDE运行项目时项目无法工作的原因。

根据Giorgio：

他们在“应用程序运行配置”中添加了一个复选框，以“包括具有“已提供”作用域的依赖项”
