自己制作的类似Struts1.x 简单web框架
1.利用servelt ，反射 实现 通过url 映射到 action类的方法中。
这个是在我参加工作那年写的，最近工作需要，写一个不使用 struts，spring，hibernate等技术的web框架，用于公司的一个非常小的小系统。
我写了一个框架，然后把之前写的struts 拿出来 简单修改了一下，看了看，自己之前写的代码 有些地方太幼稚了。
呵呵。。
--------------------
我在这列出：web.xml 修改：
<context-param>
<param-name>mjp-config</param-name>
<param-value>mjp-config-*.xml</param-value>
</context-param>
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>com.mjp.core.struts.action.ActionServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<listener>
<listener-class>com.mjp.core.struts.listener.ConfigListener</listener-class>
</listener>
-------------------
我的struts 配置文件写法；
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE action-mappings [
<!ELEMENT action-mappings (action+)>
<!ELEMENT action (forward+)>
<!ATTLIST action path CDATA #REQUIRED>
<!ATTLIST action type CDATA #REQUIRED>
<!ATTLIST forward name CDATA #REQUIRED>
<!ATTLIST forward path CDATA #REQUIRED>
<!ATTLIST forward type CDATA #IMPLIED default (redirect|forward) "forward">
]>
<action-mappings>
<action path="/login" type="com.mjp.system.action.LoginAction" >
<forward name="success" path="index.do?method=doWelcome" type="redirect"/>
<forward name="input" path="/pages/system/login.jsp" />
</action>
<action path="/index" type="com.mjp.system.action.IndexAction" >
<forward name="input" path="/pages/system/index.jsp" />
<forward name="login" path="login.do?method=doInput" type="redirect"/>
</action>
</action-mappings>
-----------------
比如jsp调用写法：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@page import="com.mjp.core.util.StringUtil"%>
<%
String path = request.getContextPath();
String error = StringUtil.nvl(request.getAttribute("error"));
String login_account = StringUtil.nvl(request.getAttribute("login_account"));
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
