如何将Java对象转换成json格式，如何将json格式数据转换成js对象

Answer 1

commons-collections-3.2.jar commons-lang.jar commons-logging-1.1.jar ezmorph-1.0.4.jar 这时在测试得到了想要的结果 Question q2 = new Question(); q2.setId(2); q2.setDescription("descrsssss"); q2.setPointInfo("pointkkkk"); q2.setType(3); Question q1 = new Question(); q1.setId(1); q1.setDescription("descrsssss"); q1.setPointInfo("pointkkkk"); q1.setType(3); JSONObject jsonObject = new JSONObject().fromObject(q2); System.out.println(jsonObject); List list = new ArrayList(); list.add(q1); list.add(q2); JSONArray jsonArr= JSONArray.fromObject(list); System.out.println(jsonArr); 输出：{"description":"descrsssss","id":2,"pointInfo":"pointkkkk","type":3} [{"description":"descrsssss","id":1,"pointInfo":"pointkkkk","type":3},{"description":"descrsssss","id":2,"pointInfo":"pointkkkk","type":3}]页面 $.post("showQuestions?type="+type,null,callbackShowQuestions,"json"); 这时在回调函数的参数data获得的就是json转换后的js对象数组， 以下标方式便可访问数组里的相应对象信息。
