然后是bean层
然后**Action,且对应Action目录下有属性文件告诉Action里的属性值需要用自己写的哪个类型转换文件转换
package com.test.converter;
import java.util.Map;
import ognl.DefaultTypeConverter;
import com.test.bean.Point;
public class PointConverter extends DefaultTypeConverter
{
@Override
public Object convertValue(Map context, Object value, Class toType)
{
if(Point.class == toType) //先是由PointAction-conversion.properties配置文件
{
Point point = new Point();
String[] str = (String[])value;
String[] paramValues = str[0].split(",");
int x = Integer.parseInt(paramValues[0]);
int y = Integer.parseInt(paramValues[1]);
point.setX(x);
point.setY(y);
return point;
}
if(String.class == toType) //在页面上需要显示时候才调用，然后再返回string类型
{
Point point = (Point)value;
int x = point.getX();
int y = point.getY();
String result = "[x=" + x + " , y=" + y + "]";
return result;
}
return null;
}
}
还有全局类型转换配置文件xwork-conversion.properties
