jsp頁面部分代碼（表單中）如下 ：
<s:hidden name="goods.buydatetime"></s:hidden>
goods對應的實體類(部分getter,setter方法已省略)：
package com.shop.jn.entity;
import java.io.serializable;
import java.util.date;
/**
* entity:goods
* @author huangwei
*
*/
public class goods implements serializable{
private static final long serialversionuid = 586940311263079808l;
private int id;
/**
* goods name
*/
private string name;
* alias of goods
private string alias;
* when goods was brought
private date buydatetime;
* when this record was modified
private date latestmoddatetime;
* the price of goods
private double price;
* the detail of the goods
private string description;
* the supermarket the goods belong
private supermarket supermarket;
public int getid() {
return id;
}
public void setid(int id) {
this.id = id;
public string getname() {
return name;
public void setname(string name) {
this.name = name;
public string getalias() {
return alias;
public void setalias(string alias) {
this.alias = alias;
public date getlatestmoddatetime() {
return latestmoddatetime;
public void setlatestmoddatetime(date latestmoddatetime) {
this.latestmoddatetime = latestmoddatetime;
public date getbuydatetime() {
return buydatetime;
public void setbuydatetime(date buydatetime) {
system.out.println("buydatetime:"+buydatetime);
this.buydatetime=buydatetime;
}
實體類中buydatetime 的類型是java.util.date
使用ie浏覽器有問題，但是使用google浏覽器沒問題。
ie的locale是en_us，見下圖：
原因到底是什麼呢?因為在火狐和谷歌浏覽器中沒問題啊
最後發現是ie浏覽器的語言環境是英文
把語言調整為中文就ok 了.
針對這個問題，我們沒法要求客戶一定設定中文為預設浏覽器的語言環境。因而對于date類型的轉換，可以自己定義一個轉換器。
package com.common.convert;
import java.sql.date;

可以将該轉換器注冊為全局的：在classpath下建立xwork-conversion.properties檔案，内容為：java.util.date=你的類型轉換器的完整限定類名
xwork-conversion.properties 内容如下:
java.util.date=com.common.convert.dateconverter
java.sql.timestamp=com.common.convert.dateconverter
