根據字串設定物件對應屬性

public static void setAttribute(Object o,String field, Object keyWord) {
    try { 
        Field f = o.getClass().getDeclaredField(field); 
        f.setAccessible(true); 
        f.set(o, keyWord); 
    } catch (Exception e) { 
        e.printStackTrace(); 
    } 
}

根據字串獲取物件對應屬性

public static String getAttribute(Object o,String field) {
    String r = "";
    try { 
        Field f = o.getClass().getDeclaredField(field); 
        f.setAccessible(true); 
        r =  f.get(o).toString();
    } catch (Exception e) { 
        e.printStackTrace(); 
    } 
    return r;
}
