本文章将介绍如何搭建一个简单的基于SSM的Java项目。

配置环境

IntelliJ IDEA 2019.2
Maven 3.6.1
jdk 1.8
tomcat 7.0
mysql 5.5

创建项目

  2. 打开IDEA，右侧选择Maven–导入jdk包–选择“Create from archetype”–选择webapp–下一步。
    如果右侧没有Maven选择，可能是没有破解–>破解IDEA请移步

  4. GroupId和ArtifactId填写无要求
  5. 选择自己安装好的Mevan库的路径。
  6. 选择1按钮，如果.m2文件下没有setting.xml文件，就选择安装Maven目录下的conf下的setting.xml文件。选择2的“+”，新建一个Mevan Property。设置Name为archetypeCatalog，Value为internal。点击下一步。
  7. 填写项目名和所存放的文件夹，点击“finsh”完成maven工程的创建。
  8. 进入该工程后，将会进行自动配置导包。选择Enable Auto-import进行自动导包。若出现BUILD SUCCESS代表项目创建成功。

项目结构和源代码

项目结构如下：红色标记的为代码部分，我会给出所有代码，并给出相关解释

源代码获取路径：
链接：https://pan.baidu.com/s/1A8O1crBFsq_XhUun2gWNJw 提取码：qmu3
复制这段内容后打开百度网盘手机App，操作更方便哦
