Point.java文件：package com.jbsoft.bean;public class Point {
private int x;
private int y;
public int getX() {
return x;
}
public void setX(int x) {
this.x = x;
}
public int getY() {
return y;
}
public void setY(int y) {
this.y = y;
}
}PointConverter.java 文件：package com.jbsoft.converter;import java.util.Map;import com.jbsoft.bean.Point;import ognl.DefaultTypeConverter;public class PointConverter extends DefaultTypeConverter { public Object convertValue(Map context, Object value, Class toType) {

//从客户端到服务器端
if(Point.class == toType){
Point point = new Point();

String [] str = (String[]) value;//String [] strPoint中存放了一个字符串为：页面中到point

String [] paramValue = str[0].split(","); //再把String[] 中的一个字符串用“ ，”分割成两个

int x = Integer.parseInt(paramValue[0]);//把分割后的字符串数组中到第一个字符放到int类型到变量中，作为X坐标
int y = Integer.parseInt(paramValue[1]);

point.setX(x);
point.setY(y);

return point;
}
//从服务器端到客户端
if(String.class == toType){
Point point = (Point) value;

int x = point.getX();
int y = point.getY();

String result = "[X:" + x + ",Y" + y + "]";

return result;
}
return null;
}

}

Answer 4

我今天也遇到了你这样的问题,不过我解决了.
我看你的代码有点问题:
PointAction-conversion.properties文件： point=com.jbsoft.action.PointAction 应该写
point=com.jbsoft.converter.PointConverter不知道你的问题有没有解决..自己调试一下了再看看吧.

Answer 5

我今天也遇到了这个问题 
 我的解决方法是去掉 xxx-conversion.properties文件后面的 分号 和空格
    希望对你能有帮助
