Java讀取資料

/*獲取執行JavaScript的執行引擎*/
        ScriptEngine engine = new ScriptEngineManager().getEngineByName("javascript");
        /*為檔案注入全域性變數*/
        Bindings bindings = engine.createBindings();
        /*設定繫結引數的作用域*/
        engine.setBindings(bindings, ScriptContext.ENGINE_SCOPE);

        // 獲得js檔案
        engine.eval(new FileReader("/class.js"));

        Map<Object,Object> map = (Map) bindings.get("classes");
        List<Class> list = new ArrayList<Class>();

        for (Map.Entry entry:map.entrySet()){
            Class class = new Class();
            Map tempmap = (Map)entry.getValue();

            Object object=tempmap.get("student");
            net.sf.json.JSONArray ja = net.sf.json.JSONArray.fromObject(object);
            @SuppressWarnings("rawtypes")
            Iterator iterator = ja.iterator();
            String str="";
            while(iterator.hasNext()){
                Object next = iterator.next();
                JSONObject jaC = net.sf.json.JSONObject.fromObject(next);
                str+="["+jaC.get("0")+","+jaC.get("1")+"]";
//                System.out.println(jaC.get("0"));
//                System.out.println(jaC.get("1"));
            }

            class.setStudent(str);

            class.setName(String.valueOf(tempmap.get("name")));

            list.add(class);

        }


 

將object中的值讀取出來

            Object object=tempmap.get("student");
            net.sf.json.JSONArray ja = net.sf.json.JSONArray.fromObject(object);
            @SuppressWarnings("rawtypes")
            Iterator iterator = ja.iterator();
            String str="";
            while(iterator.hasNext()){
                Object next = iterator.next();
                JSONObject jaC = net.sf.json.JSONObject.fromObject(next);
                str+="["+jaC.get("0")+","+jaC.get("1")+"]";
//                System.out.println(jaC.get("0"));
//                System.out.println(jaC.get("1"));
            }

            class.setStudent(str);
