struts2+hibernate 实现B2C电子商务网站的登录 、注册中验证码的实现（源码）

下边只在注册中实现

1、首先是在Action中写出生成验证码所需的方法（下边是在MemberAction.java中写）

2.在struts.xml中

[html]

<result name="checkacode" type="json">

<param name="root">cacodet</param>

</result>

<result name="register">/login.jsp</result>

<result name="registererror">/personreg.jsp</result>

<result name="login">/index.jsp</result>

<result name="loginerror">/login.jsp</result>

<result name="checkacode" type="json">

<param name="root">cacodet</param>

</result>

<result name="register">/login.jsp</result>

<result name="registererror">/personreg.jsp</result>

<result name="login">/index.jsp</result>

<result name="loginerror">/login.jsp</result>



3.在register.jsp中

[html]

<script type="text/javascript">

function reImg(){

var img = document.getElementById("picture");

img.src=img.src + "?";

}

</script>







<TR>



<TD class=mustcontent><SPAN>*</SPAN>验证码：</TD>



<td><input type="text" id="acodet" name="acode" style="width:110px" value="${randomCode}"><span id="acode"><a href="javascript:void(0);" onclick="reImg();" class="changeacode"><img id="picture" src="${pageContext.request.contextPath }/csdn/MemberAction_checkCodeImage.action?nowtime="
