SpringBoot项目如何将jar包打包成war包 原版

<packaging>war</packaging>

public class SpringBootStartApplication extends SpringBootServletInitializer {
    @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(XXXApplication.class);
    }
}

   <build>
        //指定项目打成war包的名称，如果不指定默认是项目的名称 
        <finalName>pis</finalName>

			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>		
	</build>

//在linux环境下或者cmd命令窗口中
//这种非后台运行
 java -jar xxx.jar  
//后台运行
 nohup java -jar xxx.jar &

//waeapps目录下运行war包
//启动tomcat
cd ../bin/sh start.sh 

//页面访问时需要在controller的路径上加上一个war包名称，才能正常访问
