一般来讲该工程仅依赖JDK以及该专题设计的【底层基础Jar包】 65 | - 启动/运行方式：main方法（servlet web工程除外，需要war包方式部署到外置Tomcat启动） 66 | 2. xxx-spring-framework工程：通过扩展点和Spring框架整合。只有进阶了解了Spring Framework的协同使用，才会有对原理更深一层的理解 67 | - 一般来讲该工程会依赖【Spring容器】，在上工程基础上引入Spring Framework相关依赖 68 | - 启动/运行方式：main方法（spring web工程除外，需要war包方式部署到外置Tomcat启动） 69 | 3. xxx-spirng-boot工程；一切的最终目的都是使用。而开发者必定面向更加智能化的Spring Boot开发应用 70 | - 一般来讲这是最后一步。Spring Boot是高度封装、智能化的基础框架，一切专题/组件最后都需和它整合方可使用 71 | - 启动/运行方式：main方法 72 | 73 | --- 74 | 75 | ### 联系我 76 | > -
