这个问题在这里已经有了答案：

在Tomcat10上部署SpringMVC5…部署问题（1个答案）
19小时前关门。

总结

我试图从头开始创建一个基本的spring启动应用程序，构建一个.war文件并在tomcat中运行它。我实现了在intellij中运行它，但它不是在tomcat中运行的。

我在下面解释如何重现我的问题。如果我遗漏了任何相关内容，请写一条评论。

如何创建项目？

在上生成项目https://start.spring.io/ 使用以下选项

点击按钮 Generate . 档案 demo.zip 已下载。将其解压缩为目录 demo . 它应包含以下文件：

├── HELP.md
├── demo.iml
├── mvnw
├── mvnw.cmd
├── pom.xml
└── src
    ├── main
    │   ├── java
    │   │   └── com
    │   │       └── example
    │   │           └── demo
    │   │               ├── DemoApplication.java
    │   │               └── ServletInitializer.java
    │   └── resources
    │       ├── application.properties
    │       ├── static
    │       └── templates
    └── test
        └── java
            └── com
                └── example
                    └── demo
                        └── DemoApplicationTests.java

src/main/java/com/example/demo/demoapplication.java

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

src/main/java/com/example/demo/servletilizer.java

package com.example.demo;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

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

}
``` `src/main/resources/application.properties` 是空的
添加文件 `src/main/java/com/example/demo/HelloWorldController.java` 心满意足

package com.example.demo;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloWorldController {
@RequestMapping("/")
public String index() {
return "Greetings from Spring Boot!";
}
}


#### 如何在intellij中运行项目？

在intellij中打开并加载maven项目。在菜单中选择 `Run` 及 `Run 'DemoApplication'` . 您应该在控制台中看到如下内容：

. ____ _ __ _ _
/\ / ' __ _ () __ __ _ \ \ \
( ( )__ | '_ | '| | ' / ` | \ \ \
\/ __)| |)| | | | | || (| | ) ) ) )
' || .__|| ||| |_, | / / / /

打开http://localhost:8080/ 在浏览器中。你应该看到

Greetings from Spring Boot!


#### 如何在intellij中构建.war？

挑选 `View > Tool Windows > Maven` 在菜单中，单击“运行生命周期” `clean` 及 `package` ![](https://i.stack.imgur.com/mHvuC.png)
在其他文件中，有一个 `target/demo-0.0.1-SNAPSHOT.war` 是创建的。

#### 如何在tomcat中运行项目？

注意：我在下面使用docker，以使环境尽可能重现。然而，我也尝试过用brew将tomcat安装在另一台mac上，但也遇到了同样的问题。
在终端中运行（在项目根目录中）

docker run --rm -p 8081:8080
-v ${PWD}/target/demo-0.0.1-SNAPSHOT.war:/usr/local/tomcat/webapps/demo.war
tomcat:10-jdk8

您应该获得类似以下内容的输出：

也出现在这里，但它不见了。
打开http://localhost:8081/demo/ 在浏览器中。我希望看到

正如评论中所指出的，运行Tomcat9而不是10是可行的

docker run --rm -p 8081:8080 \
  -v ${PWD}/target/demo-0.0.1-SNAPSHOT.war:/usr/local/tomcat/webapps/demo.war \
  tomcat:9-jdk8
