JSP页面部分代码（表单中）如下 ：

goods对应的实体类(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;	}		}

 实体类中buyDateTime 的类型是java.util.Date

使用IE浏览器有问题，但是使用google浏览器没问题。

IE的locale是en_US，见下图：

原因到底是什么呢?因为在火狐和谷歌浏览器中没问题啊

最后发现是IE浏览器的语言环境是英文

针对这个问题，我们没法要求客户一定设置中文为默认浏览器的语言环境。因而对于Date类型的转换，可以自己定义一个转换器。

package com.common.convert;import java.sql.Date;import java.sql.Timestamp;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Map;import ognl.DefaultTypeConverter;import org.apache.commons.lang.StringUtils;import org.apache.commons.lang3.time.DateUtils;import org.apache.log4j.Logger;/*** * 日期转换器.

可以将该转换器注册为全局的：在classpath下建立xwork-conversion.properties文件，内容为：java.util.Date=你的类型转换器的完整限定类名

xwork-conversion.properties 内容如下:

java.util.Date=com.common.convert.DateConverterjava.sql.Timestamp=com.common.convert.DateConverter
