I don't see anything glaringly wrong with what you have. I have an app that I deploy both as a jar and war simultaneously in different environments (they differ only by packaging); I have a ServletInitializerequivalent to yours and it works without issue with one primary difference.

我看不出你所拥有的有什么明显的错误。我有一个应用程序，我在不同的环境中同时部署为 jar 和 war（它们仅在包装上有所不同）；我有一个ServletInitializer和你的等价的，它可以正常工作，但有一个主要区别。

I use a maven run configuration with spring-boot:runas the "Command line" value. With that I can do no more than change the pom to reflect jar or war, run, and go. I've faced problems when switching back and forth and using a config that invokes mainin the app class. For example, just for fun I just ran an instance of the app with jar packaging and running main. Wouldn't even launch. This is just after having it jar packaged and launched using the maven config I mentioned above.

我使用 maven 运行配置spring-boot:run作为“命令行”值。有了这个，我只能更改 pom 以反映 jar 或 war、run 和 go。在来回切换和使用main在应用程序类中调用的配置时，我遇到了问题。例如，为了好玩，我只是运行了一个带有 jar 打包和运行的应用程序实例main。甚至不会启动。这是在使用我上面提到的 maven 配置将它 jar 打包并启动之后。

I would recommend starting with creating that maven run configuration and see what the results are. Here's the way to do it in Intellij so you don't have to use the command line interface.

我建议从创建该 maven 运行配置开始，看看结果是什么。这是在 Intellij 中执行此操作的方法，因此您不必使用命令行界面。

1. Choose "Edit configurations..." from the dropdown next to the play button.
2. Press the green +in the upper left-hand corner.
3. Choose to create a maven configuration.
4. Name it.
5. Add spring-boot:runto the "Command line" entry.
6. Optionally, make it "Share"d or "Single instance only".

1. 从播放按钮旁边的下拉菜单中选择“编辑配置...”。
2. 按+左上角的绿色。
3. 选择创建 maven 配置。
4. 命名它。
5. 添加spring-boot:run到“命令行”条目。
6. 或者，将其设为“共享”或“仅单个实例”。

I'm not an eclipse/sts user but I'm sure there's a similar way to do it.

我不是 eclipse/sts 用户，但我确信有类似的方法可以做到。

I don't think you need your ServletInitializer

我不认为你需要你的 ServletInitializer

your InternetMovieDatabaseApplicationwith the @SpringBootApplicationannotation should be sufficient.

您InternetMovieDatabaseApplication的@SpringBootApplication注释应该足够了。

Apparently, you're going to package your application as war, that's fine but the problem is that you're running your application through the mainmethod in InternetMovieDatabaseApplicationclass. Instead, you should either deploy your application to a Standalone Servlet Container, like Tomcator Jetty, or run the application using the mvn spring-boot:runcommand.

显然，您要将应用程序打包为war，这很好，但问题是您正在通过类中的main方法运行应用程序InternetMovieDatabaseApplication。相反，您应该将应用程序部署到独立 Servlet 容器，例如Tomcat或Jetty，或者使用mvn spring-boot:run命令运行应用程序。

If packaging your application as wararchive is not a strict requirement, i recommend to make jar, not war. In order to doing so, first remove the packagingin your pom.xml:

如果将您的应用程序打包为war存档不是一个严格的要求，我建议制作 jar 而不是 war。为此，首先删除packaging您的pom.xml：

<packaging>war</packaging>

Then remove the spring-boot-starter-tomcatdependency:

然后删除spring-boot-starter-tomcat依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

And finally remove the ServletInitializerclass and run the mainmethod in your InternetMovieDatabaseApplicationclass.

最后删除ServletInitializer该类并main在您的InternetMovieDatabaseApplication类中运行该方法。

I was having this problem, it was fixed by removing this dependency:

我遇到了这个问题，它是通过删除此依赖项来解决的：

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>

Although an answer has been accepted, still this might help:

尽管已接受答案，但这仍然可能有所帮助：

Are you trying to run the application from Intellij from Run menuor by right click and run on the class where your main is defined and you are getting above issue and the application works fine from command line?

您是尝试从运行菜单中的Intellij 运行应用程序，还是通过右键单击并在定义 main 的类上运行，并且您遇到了上述问题并且应用程序从命令行正常运行？

If above is the case, I see your pom.xmlhave dependency with providedscope.

如果是上述情况，我看到您的pom.xml依赖于提供的范围。

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-tomcat</artifactId>
   <scope>provided</scope>
</dependency>

When running the application from run menu in intellij, dependencies with provided scope are not available by default.

从 intellij 中的运行菜单运行应用程序时，默认情况下不提供具有提供范围的依赖项。

To fix this,

为了解决这个问题，

Go to Run Menu -> Edit Configuations and then select Include dependencies with provided scope

转到运行菜单 -> 编辑配置，然后选择包含具有提供范围的依赖项

Image for reference:

图片供参考：

And try to run again. This should fix the issue.

并尝试再次运行。这应该可以解决问题。

Good luck.

祝你好运。

I think you forgot add main-class in properties your pom.xml

我想你忘了在 pom.xml 的属性中添加主类

<properties>
    <start-class>org.infoowl.InternetMovieDatabaseApplication</start-class>
    <java.version>1.8</java.version>
</properties>

and modify your class as follow:

并按如下方式修改您的课程：

@SpringBootApplication
public class InternetMovieDatabaseApplication extends SpringBootServletInitializer {
   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
      return application.sources(DemoApplication.class);
   }
    public static void main(String[] args) {
        SpringApplication.run(InternetMovieDatabaseApplication.class, args);
    }
}

and open a command console, execute:

并打开命令控制台，执行：

mvn clean package

then, deploy warinto Tomcat, demo here

然后，部署war到Tomcat，demo在这里
