 <!-- spring版本号 -->

<spring.version>4.3.0.RELEASE</spring.version>

<!-- mybatis版本号 -->
<mybatis.version>3.4.4</mybatis.version>

<!-- mysql驱动版本号 -->
<mysql-driver.version>5.1.40</mysql-driver.version>

<!-- log4j日志包版本号 -->
<log4j.version>2.7</log4j.version>
<commons-logging.version>1.2</commons-logging.version>

<!-- 对象转 jackson 版本号 -->

使用maven 开发springmvc apring mybatis web项目。

1.File -> New Project ，进入创建项目窗口

 

 2 出现以下界面 

3 按照如上选项进行点击，点next

4 上面两项随便填，点击next

上面选项中可以直接使用默认配置。我修改的local repository是本地仓库位置，可以改也可以不改。下面在Properties中添加一个参数 archetypeCatalog=internal，不加这个参数，在maven生成骨架的时候将会非常慢，有时候直接卡住。来自网上的解释：archetypeCatalog表示插件使用的archetype元数据，不加这个参数时默认为remote，local，即中央仓库archetype元数据，由于中央仓库的archetype太多了所以导致很慢，指定internal来表示仅使用内部元数据。

5 点击next

这个我没有修改，点击finish

6 生成maven的项目骨架之后，我们还需要手动在 src/main 下创建 java目录。现在可以直接编写了

 到此为止，项目的框架基本搭建完成。

 

7 下面进行pom.xml进行配置

写完pom.xml文件后需要更新依赖，

点击更新。

 

 8 按照常规步骤开发SSM项目即可。

可以参考SSM整合开发流程

 

9 spring.xml项目配置，mybatis配置文件指定，spring配置，springMVC配置

10 项目部署，这几步很关键。可以参考 图文详解 IntelliJ IDEA 15 创建普通 Java Web 项目

 

 

常见问题

1 maven项目中java文件夹不能新建package和class，需要做如下设置

 

2 在idea中安装mybatis插件

选择file -> setting -> plugins，搜索mybatis，这时因为没有安装过插件，所以会出现如图所示：

点击Browse，这是会弹出如下窗口，intellij idea会自动从网络搜索插件，方便下载，如图所示：

点击Install plugin即可自动下载安装，之后重启intellij idea即可。

 

3 在进行mapper文件映射时出现 URI is not registered.解决办法如下

鼠标点击红色字，然后Intellij出现小红灯，选择Fetch external resource即可解决 

 

4 MAVEN项目jar包依赖导入问题解决，

在新建项目后，项目的路径中会生成pom.xml文件和项目名.iml文件。新建项目后，IDEA不会自动刷新Maven的依赖。刷新Maven配置的方法为：

（1）右键单击项目；

（2）在弹出菜单中选择Maven|Reimport菜单项。

此时，IDEA将通过网络自动下载相关依赖，并存放在Maven的本地仓库中。
