struts2参数转换器用法

贴代码

struts的action中接收简单类型参数，struts2可以自动转化，但是复杂类型需要自定义转换器转换

public class ConvertAction extends ActionSupport{

    private int age;
    private Date date;
    private List<String> interests;
    private String name;
    private Map<String, String> map;

    //复杂类型
    private List<Point> ps;
    public List<Point> getPs() {
        return ps;
    }
    public void setPs(List<Point> ps) {
        this.ps = ps;
    }
    //特殊类型
    private Point p;

    public Point getP() {
        return p;
    }
    public void setP(Point p) {
        this.p = p;
    }

    public Map<String, String> getMap() {
        return map;
    }
    public void setMap(Map<String, String> map) {
        this.map = map;
    }
    public int getAge() {
        return age;
    }
    public Date getDate() {
        return date;
    }
    public List<String> getInterests() {
        return interests;
    }
    public String getName() {
        return name;
    }
    public String hello(){

        System.out.println("date:"+date);
        return SUCCESS;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public void setDate(Date date) {
        this.date = date;
    }
    public void setInterests(List<String> interests) {
        this.interests = interests;
    }

    public void setName(String name) {
        this.name = name;
    }
}

public class PointConvert extends DefaultTypeConverter{

    @Override
    public Object convertValue(Object value, Class toType) {
        // TODO Auto-generated method stub
        if (toType == Point.class) {
            Point p=new Point();
            String[] values=(String[]) value;
            String[] pv = values[0].split(",");
            p.x=Integer.parseInt(pv[0]);
            p.y=Integer.parseInt(pv[1]);
            return p;
        }
        if (toType == String.class) {
            return value.toString();
        }
        return super.convertValue(value, toType);
    }

}

注册转换器：两种方式

1.局部：与action同包  XXXAction-conversion.properties

2.全局：src根目录  xwork-conversion.properties
