您可以在pom文件中排除：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <artifactId>tomcat-embed-el</artifactId>
            <groupId>org.apache.tomcat.embed</groupId>
        </exclusion>
        <exclusion>
            <artifactId>tomcat-embed-core</artifactId>
            <groupId>org.apache.tomcat.embed</groupId>
        </exclusion>
        <exclusion>
            <artifactId>tomcat-embed-websocket</artifactId>
            <groupId>org.apache.tomcat.embed</groupId>
        </exclusion>
    </exclusions>
</dependency>

您可以通过屏幕截图关注此link
嵌入式servlet容器上的Spring文档

您可以按如下方式修改POM.xml文件：

<!-- Removing the dependency for the embedded tomcat -->
            <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>

另一种方法是将tomcat依赖项的scope标记为在pom.xml中提供的：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-websocket</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-core</artifactId>
        <scope>provided</scope>
    </dependency>

字符串

在<artificatId>的依赖项中添加<exclusions>标记为'spring-boot-starter-web'

<exclusions>
    <exclusion>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-tomcat</artifactId>
    </exclusion>
</exclusions>

字符串
你的最终依赖应该看起来像这样：

<dependencies>
        <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>
</dependencies>

型

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <excludeGroupIds>org.apache.tomcat.embed</excludeGroupIds>
    </configuration>
</plugin>

最好是提一下

pom.xml文件中提供的范围

在基于Sping Boot Maven的应用程序中排除嵌入式Tomcat服务器。

    <scope>provided</scope>
</dependency>

对于Sping Boot 2.7.12版本的示例在这里。如果您使用验证，不要忘记从排除。PS：不要从目标文件夹复制war文件。它有lib提供的文件夹。使用maven-war-plugin并从其输出文件夹复制。
