springboot打包成jar_springboot精简打包

- 第一步

  ```
  @MapperScan("com.yglh.mapper")
  @SpringBootApplication
  public class YglhApplication extends SpringBootServletInitializer {
  
      public static void main(String[] args) {
  
          SpringApplication.run(YglhApplication.class, args);
      }
  
      @Override
      protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
          return builder.sources(YglhApplication.class);
      }
  
  }
  ```

- 第二步，pom

  ```
      <packaging>war</packaging>
  ```

- maven插件执行、package打包
