写出自己自定义类型转换器的实现步骤及代码
写一个注册页面
<%@ page language="java"import="java.util.*" pageEncoding="utf-8"%>
<%
String path =request.getContextPath();
String basePath =request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTDHTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'reg.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">

<link rel="stylesheet"type="text/css"

</head>
<body>
<div>
<form action="${pageContext.request.contextPath}/reg/reg.action" method="post">
用户名：<input type="text" name="uname"/><br>
年龄：<input type="text" name="uage"/><br>
薪资：<input type="text" name="usalary"/><br>
出生日期：<input type="text" name="ubirth"/><br>

<input type="radio" name="umarry"value="false"/>未婚<br>
<input type="submit" value="注册"/>
</form>
</div>
</body>
</html>
封装一个java类
package cn.csdn.hr.action;
import java.util.Date;
importcom.opensymphony.xwork2.ActionSupport;
public class DemoAction extendsActionSupport{
/**
*
*/
privatestatic final long serialVersionUID = 1L;
privateString uname;
privateInteger uage;
privateDouble usalary;
privateDate ubirth;
privateboolean umarry;
publicString getUname() {
returnuname;
}
publicvoid setUname(String uname) {
this.uname= uname;
}
publicInteger getUage() {
returnuage;
}
publicvoid setUage(Integer uage) {
this.uage= uage;
}
publicDouble getUsalary() {
returnusalary;
}
publicvoid setUsalary(Double usalary) {
this.usalary= usalary;
}
publicDate getUbirth() {
returnubirth;
}
publicvoid setUbirth(Date ubirth) {
this.ubirth= ubirth;
}
publicboolean isUmarry() {
returnumarry;
}
publicvoid setUmarry(boolean umarry) {
this.umarry= umarry;
}
@Override
publicString toString() {
return"DemoAction [uname=" + uname + ", uage=" + uage + ",usalary="
+usalary + ", ubirth=" + ubirth + ", umarry=" + umarry +"]";
}
publicString reg(){
System.out.println(toString());
returnSUCCESS;
}
}
Struts.xml文件
<?xml version="1.0"encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD StrutsConfiguration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

注册信息正确的话 就跳转到sc.jsp页面
<%@ page language="java"import="java.util.*" pageEncoding="utf-8"%>

String path =request.getContextPath();
String basePath =request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
