一些问题。

一些问题。

我自己想做一个简单的博客页面-然后我学的之前那个oa项目，但是改了一下-把里面的模块改成了两个SpringBoot项目，大概就如图commons是maven建的，另外两个都是通过Springboot的方式创建的，user中就完成了简单的注册和登陆，然后运行还报错了。

同学你好，一个maven项目形式如下：

http://img1.sycdn.imooc.com//climg/5e96c79d09c8d0d203800514.jpg

如上所示，就是一个完整的maven项目，对应都是使用maven中的pom来管理jar。

这个大项目下的子模块可以是spring boot的模块：

http://img1.sycdn.imooc.com//climg/5e96cc3f09d23e6c11290478.jpg

也可以是普通的子模块:

http://img1.sycdn.imooc.com//climg/5e96cbee09d04b3911460567.jpg



   如上所示，在这个maven项目中的子模块可以是springboot形式的模块，也可以是普通的web模块。

如果我的回答解决了你的疑惑，请采纳，祝学习愉快~

同学你好，1、同学很棒，已经可以自己解决一些问题了，在以后的开发中，自己调整问题也是很大一部分内容。

        2、对与maven和springboot，它们不是并列的，同学原来的理解错了。在maven的基础上可以创建spring boor的项目，但是"最外层是maven，里面参杂Springboot模块和maven模块得子项目"这些都是不正确的，如果使用maven创建项目，对应其中的子模块等内容也需要使用mavne形式，便于管理。

  对于Springboot中的依赖包是parent，比如在父项目与子项目的pom中：

父项目：

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>
    </parent>
    <groupId>com.imooc</groupId>
    <artifactId>base</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>

子项目：

 <parent>
        <artifactId>base</artifactId>
        <groupId>com.imooc</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

这只是一个小例子，同学参考着理解一下。

如果我的回答解决了你的疑惑，请采纳，祝学习愉快~

    还是那个地方没理解。“在maven的基础上可以创建spring boor的项目”和“如果使用maven创建项目，对应其中的子模块等内容也需要使用mavne形式”这个让我又蒙了。是不是矛盾了；Springboot用maven形式和不用maven的形式又是什么区别。

同学你好，1、根据报错信息：

http://img1.sycdn.imooc.com//climg/5e959cb20925c03f07480304.jpg

对应jar包中的类没有正确加载，同学可以尝试查看对应的类是否没有正确下载，同学可以尝试重新换一个版本，重新下载，再来试试。

    2、同学对springboot和maven的理解是有些问题的，maven是项目管理工具，而springboot是框架技术。

http://img1.sycdn.imooc.com//climg/5e959dfb092ad85809720567.jpg

创建一个spring boot的项目可以在maven的基础上创建。具体的maven的内容，同学可以再去复习一下maven的课程内容   https://class.imooc.com/course/902

如果我的回答解决了你的疑惑，请采纳，祝学习愉快~

    1.这个可以再maven得基础上创建，是不是就是可以最外层是maven，里面参杂Springboot模块和maven模块得子项目，再反过来，Springboot放在最外面，里面参杂这些子项目是不是可以。 2.Springboot有个依赖包是parent，子项目Springboot得parent要指向父项目，Springboot原本得parent又写在哪里？感觉写在父类得话，对于不是Springboot得项目好像有影响还是什么。总感觉不对。然后对于依赖引入得那些包，总感觉有重复得，而且也不知道哪些要哪些不要。跟着课程完全没这个烦恼，自己动手做才觉得难，各种报错，各种改，这个老师说的换版本什么得 ，也都做过。就是没有用。
