ssm框架集成详解

# 1. 创建maven项目 #

1.1  File -> New Module，进入创建项目窗口。

![Center][]

1.2  点击Next，填写GroupId、ArtifactId和Version

![Center 1][]

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。

![Center 2][]

1 .4  填写Module name

![Center 3][]

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。

![Center 4][]

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。

![SouthEast][]

3.2  创建一个Tomcat容器实例，并把项目部署进去

![Center 5][]

3.3  项目所需配置好项目访问的根路径，然后启动Tomcat。

![Center 6][]

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

![Center 7][]

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：

![Center 8][]

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。
