將Map轉換為對象的Java 對象

標籤：

public class MapUtil {    public static Object convert2Object(Class clazz,Map<String,Object[]> map) throws             IntrospectionException, InstantiationException, IllegalAccessException{        BeanInfo bi = Introspector.getBeanInfo(clazz);                Object obj = clazz.newInstance();                PropertyDescriptor[] pds = bi.getPropertyDescriptors();                String pName;        for(PropertyDescriptor pd:pds){            pName = pd.getName();            if(map.containsKey(pName)){                try {                    pd.getWriteMethod().invoke(obj, map.get(pName)[0]);                } catch (Exception ex) {                    Logger.getLogger(MapUtil.class.getName()).log(Level.SEVERE, null, ex);                }             }        }                return obj;    }}

使用方法：

Map<String,Object[]> map = request.getParameterMap();Request req = (Request)MapUtil.convert2Object(Request.class, map);
