今天第一次学习strut,跟着jdk学习笔记，做了个简单demo。
发现了些问题
1. eclipse创建web project, 然后在项目点右键，选择myeclipse, enable struts, 系统会自动添加struts.config.xml 和web.xml
2. struts.config.xml
<action-mappings>
<action
path="/hello"
type="net.tuolian.struts.HelloAction">
<forward
name="helloUser" <!--此处不要写错名称 -->
path="/WEB-INF/hello.jsp"/>
</action>
</action-mappings>
里面的类名和地址不要写错
3. 编写HelloAction 必须继承struts.action类， 重写exectue方法
主要的逻辑，就是获取页面的parameter
逻辑处理，保存获取的参数
业务分发给相应的jsp页面
比如
request.setAttribute("userInfo", model);
return mapping.findForward("helloUser");
具体配置文件和代码如何。依次为web.xml, struts.config.xml, HelloAction.java
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <servlet> <servlet-name>action</servlet-name> <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> <init-param> <param-name>debug</param-name> <param-value>3</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping></web-app>
