安裝spring

有兩種方式建立項目，建議使用maven項目方式，可以更好的控制jar包依賴。

dynamic web project方式

在maven中作如下配置即可（關于maven請參考本站關于maven的文章）。關于dynamic web project轉換為maven請參考：eclipse java工程跟maven工程的互相轉換加入spring mvc的方式，直接在pom.xml里面加入以下代碼即可：

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.2.13.RELEASE</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.2.13.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.2.13.RELEASE</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.2.13.RELEASE</version>
</dependency>

注意加入后要更新eclipse項目。 QQ截圖20150113145555

配置與Hello World基于maven

1、修改pom.xml，添加必要依賴

2、添加配置文件

applicationContext.xml
