Insert.jsp代码如下：
<%@ taglib uri=“/WEB-INF/struts-logic.tld” prefix=“logic” %>
<html:html locale=“true”>
<head>
<html:base />
</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>
PrepareInsertAction代码如下：
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”);
}
}
InsertAction代码如下：
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”);
}
}
}
ModifyForm代码如下：
public class ModifyForm extends ActionForm {
public void reset(ActionMapping mapping, HttpServletRequest request) {
this.address=null;
this.name=null;
this.phone=null;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
Struts-config.xml配置如下：
<struts-config>
<data-sources />
<form-beans >
<form-bean name=“modifyForm” type=“com.lyx.struts.form.ModifyForm” />
</form-beans>
<global-exceptions />
<global-forwards>
<forward name=“inserttoken” path=“/tokeninsert.jsp”/>
</global-forwards>
<action-mappings >
<!–插入记录时token检验第一个跳的action –>
<action path=“/prepareInsert” type=“com.lyx.struts.action.PrepareInsertAction” />
<!–插入记录时token检验后的第二个action –>
<action
attribute=“modifyForm”
name=“modifyForm”
path=“/insert”
scope=“request”
type=“com.lyx.struts.action.InsertAction” />
</action-mappings>
<message-resources parameter=“com.lyx.struts.ApplicationResources” />
</struts-config>
Applicationresources.properties配置如下：
error.invalid.token=repeatsubmit
label.user=username
lable.phone=phone
label.address=address
modify.add=add
label.tokeninsert=tokeninsert
button.reset=reset
