【spring Boot】2.在Myecplise上把spring Boot项目打包 war包和jar包

========================================================第一部分=============================================================

第一部分：使用maven项目中自带的插件，将maven的web项目打包成war包

使用的项目是上一章中的maven项目，原封不动

看一下pom.xml文件

  </build>

    <!-- 引入parent项目，其实就是一个项目jar,版本自己在http://mvnrepository.com/search?q=spring-boot-starter-parent 选择即可 -->

        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.7.RELEASE</version>
    </parent>
  
      <!-- 要跑起来一个web项目，就引入这一个jar即可，版本不用写，parent中已经声明了的 -->
