如何调整Angular-SpringBoot-Maven构建以生成Tomcat可部署WAR包？

1. 修改delivery模块的启动类 #

让delivery模块的Spring Boot启动类继承SpringBootServletInitializer，重写configure方法，这是Spring Boot应用部署到外部Servlet容器的必要步骤：

@SpringBootApplication
public class DeliveryApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DeliveryApplication.class);
    }

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

2. 配置delivery模块的pom.xml实现多打包类型 #

在delivery模块的pom.xml中添加Maven Profiles，分别控制JAR和WAR的构建逻辑，同时保留默认JAR输出：

<!-- 默认打包类型为JAR -->
<packaging>jar</packaging>

<profiles>
    <!-- 默认激活的JAR构建Profile -->
    <profile>
        <id>jar</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackage</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>

    <!-- WAR构建Profile -->

        <id>war</id>
        <build>
            <plugins>
                <!-- 保留Spring Boot重打包逻辑 -->

3. 执行构建 #

• 生成JAR包（默认）：

  mvn clean package
  

• 生成WAR包：

  mvn clean package -Pwar
  

• 一次构建同时生成JAR和WAR：

  mvn clean package -Pboth
  

4. 验证WAR部署 #

将生成的WAR包放入Tomcat的webapps目录，启动Tomcat后，应用会自动解压部署。访问路径为http://<tomcat-host>:<port>/<war包名称>（若需要根路径部署，可将WAR包重命名为ROOT.war）。
