struts2.1.6和2.1.8中的类型转换问题，都配置好了但是执行没效果打印出来是null 给我自己的感觉是根本没有进去DateTypeConvert 类执行convertValue方法
转换器代码：
package com.lovo.convert;
import java.sql.Date;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Map;
import com.opensymphony.xwork2.conversion.impl.DefaultTypeConverter;
/**
* 自定义类型转换器
* @author lucky_xingxing
*
*/
public class DateTypeConvert extends DefaultTypeConverter {
@Override
public Object convertValue(Map<String, Object> context, Object value,
Class toType) {
try {
SimpleDateFormat simple = new SimpleDateFormat("yyyymmdd");
if(toType == Date.class){
String [] values = (String []) value; //request.getParameterValues()
System.out.println(simple.parse(values[0]));
return simple.parse(values[0]);
}else if(toType==String.class){
Date date = (Date)value;
return simple.format(date);
}
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
Action的代码：
package com.lovo.convert;
import java.util.Date;
public class ConvertAction {
private Date date;
public String execute(){
System.out.println(date);
return "succes";
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
}

date=com.lovo.convert.DateTypeConvert
