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

http://blog.csdn.net/gallenzhang/article/details/51932152

 

本篇文章主要内容是介绍如何使用IntelliJ IDEA创建Spring + SpringMVC + MyBatis项目,下面会给出项目搭建的详细步骤以及相关的配置文件。

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。

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
