[呵呵哒 .]

package util;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Map;

import javax.swing.text.DateFormatter;

import org.apache.struts2.util.StrutsTypeConverter;

import com.opensymphony.xwork2.conversion.TypeConversionException;




public class DateConverter extends StrutsTypeConverter{
private final DateFormatter[] dfs={
new SimpleDateFormat("yyyy年MM月dd日"),
new SimpleDateFormat("yyyy-MM-dd"),
new SimpleDateFormat("MM/dd/yy"),
new SimpleDateFormat("yyyy.MM.dd"),
new SimpleDateFormat("yyMMdd"),
new SimpleDateFormat("yyyy/MM/dd"),
new SimpleDateFormat("pattern")
};

@Override
public Object convertFromString(Map context, String[] values, Class toType) {
String dateStr=values[0];
for (int i = 0; i < dfs.length; i++) {
try {
return dfs[i].parse(dateStr);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
throw new TypeConversionException();

}

@Override
public String convertToString(Map context, Object obj) {
Date date=(Date)obj;
return new SimpleDateFormat("yyyy-MM-dd").format(date);
}

}
