Springboot同时出Jar和War

修改maven配置
为同时支持war / jar部署，主程序的pom.xml需作如下修改，该配置默认以jar方式打包；以war方式打包须使用命令 mvn package -Pwar

请移除原有maven-jar-plugin，并保证在项目里有默认application.properties文件（配置可使用本地配置）

<packaging>${packaging.type}</packaging>

修改启动类
启动类须继承SpringBootServletInitializer

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