Json转java对象和List集合

public static void main(String[] args) { 

    // 转换对象
    String strJson ="{\"basemenu_id\":\"1\",\"basemenu_name\":\"aaaaaa\",\"basemenu_order\":\"2\"}";
    aaaa jb = (aaaa)json2Object(strJson,aaaa.class);//javabean 要加 ".class"
    System.out.print("json转对象"+jb.getBasemenu_id()+","+jb.getBasemenu_name()+","+jb.getBasemenu_order()+"\n");  

    //转list
    String json="[{\"basemenu_id\":\"1\",\"basemenu_name\":\"aaaaaa\",\"basemenu_order\":\"2\"},"
    + "{\"basemenu_id\":\"2\",\"basemenu_name\":\"cccccc\",\"basemenu_order\":\"3\"},"
    + "{\"basemenu_id\":\"3\",\"basemenu_name\":\"dddddd\",\"basemenu_order\":\"4\"},"
    + "{\"basemenu_id\":\"4\",\"basemenu_name\":\"bbbbbb\",\"basemenu_order\":\"5\"},"
    + "{\"basemenu_id\":\"5\",\"basemenu_name\":\"eeeeee\",\"basemenu_order\":\"6\"},"
