我已经使用 Spring boot 编写了一个 spring 批处理应用程序。当我尝试在本地系统上使用命令行和类路径运行该应用程序时，它运行良好。但是，当我尝试在 linux 服务器上运行它时，它给了我以下异常
Unable to start web server; nested exception is
org.springframework.context.ApplicationContextException:
Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.
Below is the way I am running it:

Case 1:
情况1：
@SpringBootApplicationannotation missing in your spring boot starter class.
@SpringBootApplication您的 Spring Boot 入门类中缺少注释。
Case 2:
案例2：
For non web application, disable web application typein properties file:
对于非 Web 应用程序，请web application type在属性文件中禁用：
In application.properties:
在application.properties：
spring.main.web-application-type=none
If you use application.ymlthen add:
如果您使用application.yml然后添加：
spring:
main:
web-application-type: none
For web applications, extends *SpringBootServletInitializer*in main class.
对于 Web 应用程序，*SpringBootServletInitializer*在主类中扩展。
@SpringBootApplication
public class YourAppliationName extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(YourAppliationName.class, args);
}
}
Case 3:
案例3：
If you use spring-boot-starter-webfluxthen also add spring-boot-starter-webas dependency.
如果您使用spring-boot-starter-webfluxthen 也添加spring-boot-starter-web为依赖项。

Upgrading spring-boot-starter-parentin pom.xmlto the latest version fixed it for me.
升级spring-boot-starter-parent的pom.xml最新版本，固定对我来说。

I had this problem during migration to Spring Boot. I've found a advice to remove dependenciesand it helped. So, I removed dependency for jsp-apiProject had. Also, servlet-apidependency has to be removed as well.
我在迁移到 Spring Boot 时遇到了这个问题。我找到了删除依赖项的建议，它有所帮助。所以，我删除了对jsp-api项目的依赖。此外， 还必须删除servlet-api依赖项。

Probably you missing @SpringBootApplicationin your spring boot starter class.
可能您错过@SpringBootApplication了 Spring Boot 入门课程。
@SpringBootApplication
public class LoginSecurityAppApplication {
public static void main(String[] args) {
SpringApplication.run(LoginSecurityAppApplication.class, args);
}
}

I encountered this problem when attempint to run my web application as a fat jarrather than from within my IDE (IntelliJ).
当我尝试将我的 Web 应用程序作为一个胖 jar而不是从我的 IDE (IntelliJ) 中运行时，我遇到了这个问题。
This is what worked for me. Simply adding a default profile to the application.propertiesfile.
这对我有用。只需将默认配置文件添加到application.properties文件即可。
spring.profiles.active=default
You don't have to use default if you have already set up other specific profiles (dev/test/prod). But if you haven't this is necessary to run the application as a fat jar.
如果您已经设置了其他特定配置文件 (dev/test/prod)，则不必使用默认值。但是，如果您还没有，这对于将应用程序作为胖 jar 运行是必要的。

Annotate class public static void mainwith, for example: @SpringBootApplication

You probably use this in your project:
您可能会在您的项目中使用它：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
in which case you'll have to also add:
在这种情况下，您还必须添加：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
and the magic happens :)
奇迹发生了:)
PS: that's because Spring will use by default web-MVCinstead of web-fluxwhen both are available
PS：那是因为当两者都可用时，Spring 将默认使用web-MVC而不是web-flux

In my case, the problem was I didn't had a Tomcat server separately installed in my eclipse. I assumed my Springboot will start the server automatically within itself.
就我而言，问题是我的 eclipse 中没有单独安装 Tomcat 服务器。我假设我的 Springboot 会自动启动服务器。
Since my main class extends SpringBootServletInitializerand override configuremethod, I definitely need a Tomcat server installed in my IDE.
由于我的主类扩展SpringBootServletInitializer和覆盖configure方法，我肯定需要在我的 IDE 中安装一个 Tomcat 服务器。
To install, first download Apachce Tomcat (version 9 in my case) and create server using Servers tab.
要安装，首先下载 Apache Tomcat（在我的例子中是版本 9）并使用 Servers 选项卡创建服务器。
After installation, run the main class on server.
安装后，在服务器上运行主类。
Run As -> Run on Server

My solution had to do with a bad dependency. I had:
我的解决方案与不良依赖有关。我有：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
In my pom and I had to comment out the exclusion to get it working. It must look for this tomcat package for some reason.
在我的 pom 中，我不得不注释掉排除以使其正常工作。出于某种原因，它必须寻找这个 tomcat 包。
