2.Struts2的类文件加载目录:D:/云盘同步文件夹/JAVA开发/JAR包/struts-2.3.15.3/src/core/src/main/java
3.Struts2的doc的加载目录:file:/D:/云盘同步文件夹/JAVA开发/JAR包/struts-2.3.30/docs/struts2-core/apidocs/
4.Struts2的DTD文件:http://struts.apache.org/dtds/struts-2.3.dtd
5.要用就用ActionSupport,即
public class Product extends ActionSupport { @Override public String execute() throws Exception { // TODO Auto-generated method stub return super.execute(); } }6.文件路径问题
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <span style="color:#ff0000;"><% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> </span> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <span style="color:#ff0000;"><base href="<%=basePath%>"/> </span><title>Insert title here</title> </head> <body> <a href="product-input.action">Product Input</a> <br><br> <a href="test.action">Test</a> </body> </html>
7.动态方法调用(DMI)
8.用通配符匹配action标签
<action name="*_*" class="com.javaweb.struts2.action.{1}Action" method="{2}"> <result>/{1}_{2}.jsp</result> </action>9.Action接收参数的3种方式:
①.用setName()方法来赋值。
②用实体类来赋值。
③ModelDriver模型驱动接口来实现赋值。
10.中文乱码问题,在struts.xml文件中加入:
<constant name="struts.i18n.encoding" value="UTF-8"></constant>
11.值栈的访问和使用。
