建一个Insert.jsp页面代码如下：
<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html:html locale="true">
<head>
<html:base />
<title>insert.jsp</title>
</head>
<body>
<html:form action="insert" method="post">
<bean:message key="label.name"/><html:text property="name" />
<bean:message key="label.phone"/><html:text property="phone"/>
<bean:message key="label.address"/><html:text property="address"/>
<html:submit ><bean:message key="modify.add"/></html:submit>
<html:reset><bean:message key="button.reset"/></html:reset>
</html:form>
<html:errors/>
</body>
</html:html>
建一个InsertAction代码如下：
//Created by MyEclipse Struts
// XSL source (default): platform:/plugin/com.genuitec.eclipse.cross.easystruts.eclipse_4.1.1/xslt/JavaClass.xsl

package com.yourcompany.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.yourcompany.bean.ListBean;
import com.yourcompany.struts.form.ModifyForm;

/**
* MyEclipse Struts
* Creation date: 02-20-2007
*
* XDoclet definition:
* @struts.action validate="true"
*/
public class InsertAction extends Action {
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModifyForm modifyForm = (ModifyForm) form;
//得到token
String token_request =request.getParameter("org.apache.struts.taglib.html.TOKEN");
//打出来看看是什么东东
System.out.println("token in request is:"+ token_request);
ActionErrors errors = new ActionErrors();
//判断token是否有效,如果为假证明有重复提交，声明一个错误信息，并反馈出来
if(!isTokenValid(request)){
errors.add("insettoken",new ActionError("error.invalid.token"));

saveErrors(request, errors);
saveToken(request);
return (new ActionForward(mapping.getInput()));
}
//当用户首次提交时返!isTokenValid()返回true
else{
resetToken(request);
}
int result=new ListBean().add(modifyForm);

if(result==1){
return mapping.findForward("addlist");
}else{
return mapping.findForward("error");
}
}

}
建一个PrepareInsertAction代码如下：
package com.yourcompany.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

/**
* MyEclipse Struts
* Creation date: 02-20-2007
*
* XDoclet definition:
* @struts.action validate="true"
*/
public class PrepareInsertAction extends Action {
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
System.out.print("hello PrepareInsertAction");
//创建一个新的令牌
saveToken(request);
return mapping.findForward("inserttoken");
}
}
