概述：下面通过jsp提交输入注册信息信息，同时完成过程文件国家化问题演示说明。【注册日期转换用注解方式实现】
工程截图：
注册页面jsp文件：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="tycoon"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <!-- method 默认为：post --> <tycoon:form action="regist" method="post"> <tycoon:textfield label="用户名" name="username"></tycoon:textfield> <tycoon:password label="密码" name="password"></tycoon:password> <tycoon:password label="确认密码" name="repassword"></tycoon:password> <tycoon:textfield label="生日" name="birthday"></tycoon:textfield> <tycoon:textfield label="年龄" name="age"></tycoon:textfield> <tycoon:submit value="登录"></tycoon:submit> </tycoon:form> </body> </html>
success.jsp(成功后跳转页面)：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="tycoon"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>success</title> </head> <body> 欢迎,<tycoon:property value="username" />登陆</br> 密码为,<tycoon:property value="password" /></br> 生日,<tycoon:property value="birthday" /></br> 年龄,<tycoon:property value="age" /></br> </body> </html>
Regist.java(注册页面action文件)：
package com.tycoon.usermanager;
import java.util.Date;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.conversion.annotations.TypeConversion;
public class RegistAction extends ActionSupport {
/**
* 东北大亨
*/
private static final long serialVersionUID = -1245514962211959620L;
private String username;
private String password;
private String repassword;
private Date birthday;
private Integer age;
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRepassword() {
return repassword;
}
public void setRepassword(String repassword) {
this.repassword = repassword;
}
// 注解方式实现注册页面日期类型转换
@TypeConversion(converter="com.tycoon.common.DataConver3")
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
public String execute() throws Exception {
System.out.println("调用registAction execute() ");
return SUCCESS;
}
}
日期类型转换类：
package com.tycoon.common;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Map;
import org.apache.struts2.util.StrutsTypeConverter;
/**
* 东北大亨
* @author tycoon
*
*/
public class DataConver3 extends StrutsTypeConverter {
private SimpleDateFormat[] sdfs = new SimpleDateFormat[] { new SimpleDateFormat("yyyy-MM-dd"),
new SimpleDateFormat("yyyy年MM月dd日"), new SimpleDateFormat("yyyy/MM/dd") };
@Override
public Object convertFromString(Map context, String[] values, Class arg2) {
if (values == null)
return null;
Date dt = null;
for (SimpleDateFormat sdf : sdfs) {
try {
dt = sdf.parse(values[0]);
return dt;
} catch (ParseException e) {
continue;
}
}
return null;
}
@Override
public String convertToString(Map context, Object value) {
if (null == value)
return null;
if (value instanceof Date) {
Date df = (Date) value;
System.out.println(" DataConver2 :" + "convertToString");
return sdfs[0].format(df);
}
return null;
}
}
国际化文件key及value值：
（1）message_en_US.properties 文件内容：
xwork.default.invalid.fieldvalue=Invalid field value for field "{0}"
（2）message_zh_CN.properties 文件内容：
xwork.default.invalid.fieldvalue=u4F60u8F93u5165u7684u683Cu5F0Fu4E0Du6B63u786E
struts.xml文件：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- 配置全局国家化资源文件 jsp页面和Action都可以使用 -->
<constant name="struts.custom.i18n.resources" value="message"/>
