1，创建struts2 工程，工程结构图如下：
2，convertor.DateTimeConvertor.java代码如下：
View Code
package convertor;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Map;
import ognl.DefaultTypeConverter;
public class DateTimeConvertor extends DefaultTypeConverter {
//日期格式化器，完成格式如2007-08-06，2007/08/06，07-08-06的定义
private DateFormat[] dateFormat={ new SimpleDateFormat("yyyy-MM-dd"),
new SimpleDateFormat("yyyy/MM/dd"),new SimpleDateFormat("yy-MM-dd"),};
//时间格式化器，完成格式如12：30：1100，12：30的定义
private DateFormat[] timeFormat={ new SimpleDateFormat("HH:mm:ssss"),
new SimpleDateFormat("HH:mm"),};
@SuppressWarnings("unchecked")
public Object convertValue(Map context,Object value,Class toType){
if(toType.equals(java.sql.Date.class)){//如果是java.sql.Date.class类型
String[]parameterValues=(String[])value;//获取原始字符串数据
for(DateFormat format:dateFormat)
try{ //使用3种格式化器转换日期
return new java.sql.Date(format.parse(parameterValues[0]).getTime());
}catch(ParseException e){}
}else if(toType.equals(java.sql.Time.class)){//如果是java.sql.Time.class类型
String[]parameterValues=(String[])value;//获取原始字符串数据
for(DateFormat format:timeFormat)
try{ //使用2种格式化器转换日期
return new java.sql.Time(format.parse(parameterValues[0]).getTime());
}catch(ParseException e){}
}else if(toType.equals(java.util.Date.class)){//如果是java..Date.class类型
String[]parameterValues=(String[])value;//获取原始字符串数据
for(DateFormat format:dateFormat)
try{ //使用3种格式化器转换日期
return format.parse(parameterValues[0]);
}catch(ParseException e){}
}else if(toType.equals(String.class)){ //如果时字符串
if(value instanceof java.sql.Date){
}else if(value instanceof java.sql.Time){
}else if(value instanceof java.util.Date){
return dateFormat[0].format((java.util.Date)value);
} //将Date类型转换为String类型
}
return super.convertValue(context, value, toType);//否则调用父类方法
}
}
3，创建struts2的配置文件xwork-conversion.properties，放在src路径下，具体代码如下：
View Code
java.sql.Date=convertor.DateTimeConvertor
java.sql.Time=convertor.DateTimeConvertor
java.util.Date=convertor.DateTimeConvertor
4，创建action.ConvertorAction.java代码如下：
View Code
package action;
import java.sql.Date;
import java.sql.Time;
import com.opensymphony.xwork2.ActionSupport;
public class ConvertorAction extends ActionSupport {
private Date sqlDate;
private Time sqlTime;
private java.util.Date utilDate;
public Date getSqlDate() {
return sqlDate;
}
public void setSqlDate(Date sqlDate) {
this.sqlDate = sqlDate;
}
public Time getSqlTime() {
return sqlTime;
}
public void setSqlTime(Time sqlTime) {
this.sqlTime = sqlTime;
}
public java.util.Date getUtilDate() {
return utilDate;
}
public void setUtilDate(java.util.Date utilDate) {
this.utilDate = utilDate;
}
/**
* @return
*/
public String execute() {
// TODO Auto-generated method stub
return INPUT;
}
public String convert(){
return SUCCESS;
}
}
5，创建struts.xml,
View Code
<?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> <package name="main" extends="struts-default"> <action name="convertor" class="action.ConvertorAction" converter="convertor.DateTimeConvertor"> <result name="input">/convert.jsp</result> <result name="success">/convertSuccess.jsp</result> </action> </package> </struts>
6,web.xml文件配置如下：
View Code
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> <init-param> <param-name>struts.action.extension</param-name> <param-value>action</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
7，用户界面包括convert.jsp convertSuccess.jsp
convert.jsp如下：
View Code
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@taglib uri="/struts-tags" prefix="struts" %> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'convert.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" href="styles.css"> --> </head> <body> <struts:form action="convertor"> <struts:label label="转换器"></struts:label> <struts:textfield name="sqlDate" label="SQL Date："></struts:textfield> <struts:textfield name="sqlTime" label="SQL Time:"></struts:textfield> <struts:textfield name="utilDate" label="Util Date:"></struts:textfield> <struts:submit value="提交" method="convert"></struts:submit> </struts:form> </body> </html>
convertSuccess.jsp如下：
View Code
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@taglib uri="/struts-tags" prefix="struts" %> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'convertSuccess.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" href="styles.css"> --> </head> <body> java.sql.Date:<struts:property value="sqlDate"/><br/> java.sql.Time:<struts:property value="sqlTime"/><br/> java.util.Date:<struts:property value="utilDate"/><br/><br/> <a href="convertor.action">重新转换</a> </body> </html>
8，发布即可
