本文详细介绍如何在Eclipse中使用Maven配置Spring Boot项目，将其打包为WAR文件，并通过修改启动类支持外部Tomcat部署。包括配置pom.xml、调整资源路径、启用调度等步骤。

1、eclipse springboot打war包

1. 配置pom.xml文件

<packaging>war</packaging>

<!-- Spring boot springframework -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<!-- 移除嵌入式tomcat插件 -->
			<!-- <exclusions>
				<exclusion>
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-starter-tomcat</artifactId>
				</exclusion>
			</exclusions>-->
		</dependency>
		<dependency>
			<groupId>org.apache.tomcat</groupId>
			<artifactId>tomcat-servlet-api</artifactId>
			<version>8.0.36</version>
			<scope>provided</scope>
		</dependency>

<resources>
    <!-- 打包时将页面文件拷贝到META-INF目录下 -->
    <resource>
        <!-- 指定resources插件处理哪个目录下的资源文件 -->
        <directory>src/main/webapp</directory>
        <!--注意此次必须要放在此目录下才能被访问到 -->
        <targetPath>META-INF/resources</targetPath>
        <includes>
        <include>**/**</include>
        </includes>
    </resource> 
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/**</include>
        </includes>
        <filtering>false</filtering>
    </resource>
    <resource>
        <directory>src/main/java</directory>
        <excludes>
            <exclude>**/*.java</exclude>
        </excludes>
    </resource>
</resources>

2、修改springboot启动类, 添加@EnableScheduling注解, 继承SpringBootServletInitializer类, 新增configure方法

@EnableScheduling
public class DemoApplication extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
    /**
     *新增此方法
     */
     @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
       // 注意这里要指向原先用main方法执行的Application启动类
       return builder.sources(DemoApplication .class);
    }
}

3、修改项目Maven，右键项目properties
