.NET与java的MVC模式(1):struts2入门

struts2已经是出来好久了,觉得有必要对.NET与java的MVC模式进行以下比较:

先谈下struts2的原理,不过先来入门吧

1.先安装eclipse,我只会eclipse.

2.安装jdk,tomcat

3.下载struts2的库

4.新建一个eclipse java工程

选择tomcat project

输入工程名称:TestMvc

点击完成

5.引入struts库文件

复制这些文件到，相应目录，如下：

引入库之后，需要把它们列入编译路径中：

点add jar

把他们全部加入到编译环境中

6.搭建web.xml和struts.xml（为什么以后解释）

目录结构如下：（千万不能搞错了）

web.xml

<? xmlversion="1.0"encoding="GBK" ?>
< web-app xmlns ="http://java.sun.com/xml/ns/j2ee" xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation ="http://java.sun.com/xml/ns/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version ="2.4" >
< display-name > Struts2.0Sample </ display-name >
< filter >
< filter-name > action2 </ filter-name >
< filter-class >
org.apache.struts2.dispatcher.FilterDispatcher
</ filter-class >
</ filter >
< filter-mapping >
< filter-name > action2 </ filter-name >
< url-pattern > /* </ url-pattern >
</ filter-mapping >
</ web-app >

struts.xml

<? xmlversion="1.0"encoding="GBK" ?>
<! DOCTYPEstrutsPUBLIC"-//ApacheSoftwareFoundation//DTDStrutsConfiguration2.0//EN""http://struts.apache.org/dtds/struts-2.0.dtd" >
< struts >
< include file ="struts-default.xml" />
< package name ="struts2" extends ="struts-default" >
< action name ="add"
class ="edisundong.AddAction" >
< result > add.jsp </ result >
</ action >
</ package >
</ struts >

7.AddAction.java

packageedisundong;

importcom.opensymphony.xwork2.ActionSupport;

public class AddActionextendsActionSupport ... {
/**//**
*
*/
privatestaticfinallongserialVersionUID=1L;
privateintone;
privateintanother;
privateintsum;

publicintgetAnother()...{
returnanother;
}

publicvoidsetAnother(finalintanother)...{
this.another=another;
}

publicintgetOne()...{
returnone;
}

publicvoidsetOne(finalintone)...{
this.one=one;
}

publicintgetSum()...{
returnsum;
}

publicvoidsetSum(finalintsum)...{
this.sum=sum;
}

publicStringexecute()throwsException...{
this.sum=this.one+this.another;
return"success";
}
}

8.测试

输入http://localhost:8080/TestMvc/add.jsp

输入123 和 456

结果

结束！

不好意思，实在是写的太简单了，改日分析一下，呵呵，睡觉了
