struts2参数转换器用法---2

//第二种转换器写法
public class PointConvert2 extends StrutsTypeConverter{

    @Override
    public Object convertFromString(Map context, String[] values, Class toClass) {
        // TODO Auto-generated method stub
        Point p = new Point();
        String[] strs = (String[])values;
        String[] xy = strs[0].split(",");
        p.x = Integer.parseInt(xy[0]);
        p.y = Integer.parseInt(xy[1]);
        return p;
    }

    @Override
    public String convertToString(Map context, Object o) {
        // TODO Auto-generated method stub
        return o.toString();
    }

}

以point为例，复杂参数传递方式

list<point> ps:   参数传递?ps[0].x=1&ps[0].y=2&ps[1].x=11&ps[1].y=22

map<string,point> map:  参数传递?map[‘a‘]=1,2&map[‘b]=11,21
