token机制防止重复提交

场景：使用Struts的Token机制防止重复提交的有关问题的简单测试

使用Struts的Token机制防止重复提交的问题的简单测试!
参考各位老大的经验，测试代码如下:
input.jsp:

引用

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ page contentType="text/html; charset=GBK" %>
<html:html>
<head><title>Test</title></head>
<body>
<html:form action="/testAction.do" method="post">
<br>
<html:text property="name"/>
<br>
<html:text property="pass"/>
<br>
<html:submit property="submit" value="Submit"/><br>
</html:form>
</body>
</html:html>

success.jsp:

引用

<%@ page contentType="text/html; charset=GBK" %>
<html><head><title>success</title></head>
<body bgcolor="#ffffff">
success!
</body>
</html>

TestForm:

引用

package test;

import javax.servlet.http.*;

import org.apache.struts.action.*;

public class TestForm extends ActionForm {
    private String name;
    private String pass;

    public void setPass(String pass) {
        this.pass = pass;
    }

    public void setName(String name) {
        this.name = name;
    }

        public String getName() {
        return name;
    }

    public String getPass() {
        return pass;
    }

    public ActionErrors validate(ActionMapping actionMapping,
                                 HttpServletRequest httpServletRequest) {
        /** @todo: finish this method, this is just the skeleton.*/
        return null;
    }

    public void reset(ActionMapping actionMapping,
                      HttpServletRequest servletRequest) {
    }
}

TestAction:

引用

package test;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.Action;
import org.apache.log4j.Logger;

public class TestAction extends Action {
    private static final transient Logger log = Logger.getLogger(TestAction.class);
    public ActionForward execute(ActionMapping mapping, ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) {
        TestForm testForm = (TestForm) form;
       if (testForm.getName() == null) {
            saveToken(request);
            return mapping.getInputForward();
        }
        if (!isTokenValid(request)) {
            saveToken(request);
            log.debug("不能重复提交!");
            return mapping.getInputForward();
        }
        log.debug("添加成功!");
        resetToken(request);
        return mapping.findForward("success");

    }

}

struts-config.xml:

引用

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
<struts-config>
<form-beans>
    <form-bean name="testActionForm" type="test.TestForm"/>
</form-beans>
<action-mappings>
    <action name="testActionForm" path="/testAction" type="test.TestAction" scope="request" input="/index.jsp" validate="false">
      <forward name="success" path="/success.jsp"/>
    </action>
     </action-mappings>
<message-resources parameter="ApplicationResources"/>
</struts-config>

编写完上边的代码后:http://localhost:8080/test/testAction.do可以进行测试!

如果使用velocity模板，而不使用struts的标签（velocity），在struts2下怎么解决重复提交问题呢？

2 楼 sunsy 2007-04-20

WEBWORK以前在页面上可以用标签来声明一个TOKEN，现在STRUTS要写在ACTION里吗？

因为要在action里面判断token是否合法
