[转] SSM框架整合（IntelliJ IDEA + maven + Spring + SpringMVC + MyBatis）

1. 创建maven项目

 

1.1  File -> New Module，进入创建项目窗口。

 

 

 

1.2  点击Next，填写GroupId、ArtifactId和Version

 

 

 

1.3  接着下一步，这里需要注在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。

 

 

 

 

 

1.4  填写Module name

1.5  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，我把项目所需要的文件都编写完成之后，项目的工程结构如图。

 

 

      到此为止，项目的框架基本搭建完成，下面重点说一下项目的配置文件

 

2.  项目配置文件

 

 2.1   这里使用maven来引入项目所需要的jar包，所以也就不需要手动来管理jar包了。

 

pom.xml

3.  项目配置和部署

 

3.1   File -> Project Structure，进入创建项目配置窗口。

 

 

 

3.2  创建一个Tomcat容器实例，并把项目部署进去

    

 

3.3  项目所需配置好项目访问的根路径，然后启动Tomcat。

 

 

3.4  在浏览器地址栏中输入：http://localhost:8080/web-ssm/user/showUser

 

3.5  项目所需看到图中显示效果，则表示项目搭建成功。

 

 

4.  值得注意的地方

 

搭建好项目的框架之后，启动Tomcat，如果访问 http://localhost:8080/user/showUser 出现如下错误：

出现这个错误是因为少了依赖的jar包，只要在pom文件中添加如下依赖即可。
