JSONArray用与不用的区别

List<TopicSectionBean> MisTypes = topicSectionService.selectSectionList();

第一种方式：

/*

StringBuffer b = new StringBuffer();

b.append("[");

if (MisTypes.size() > 0) {

for (Iterator iter = MisTypes.iterator(); iter.hasNext();) {

TopicSectionBean bean = (TopicSectionBean) iter.next();

b.append("{key:\"").append(bean.getKey()).append("\",sectionName:\"")

.append(bean.getSectionName()).append("\"}");

if(iter.hasNext()){

b.append(",");

}

}

}

b.append("]");

System.out.println(b.toString()+":所有版块");

response.getWriter().print(b.toString());*/

第二种方式：

/*JSONArray json=JSONArray.fromObject(MisTypes);

response.getWriter().print(json);*/
