springboot本地打war包

1、pom.xml修改图里标注的①②，新增③，图片下面有我打包的pom.xml大家可以参考

        </dependency>
        <!--添加servlet-api的依赖,用来打war包 -->

            </plugin>
        </plugins>
    </build>

</project>

2、修改启动类我标注的，同样图片下可有参考的代码

package com.milotnt;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class GymManagementSystemApplication extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(GymManagementSystemApplication.class);
    }
}

3、点击右侧maven

4、打包，先点击clean，在点击package

5、查看是否打包成功
