后台将对象转换为json格式 前台js解析json数据 将字符串转化为数组

后台Action

public void selectReadersById1(){

HttpServletRequest request=ServletActionContext.getRequest();

HttpServletResponse response= ServletActionContext.getResponse();

String id=request.getParameter("readerId");//接收jsp页面传的参数读者id

Readers readers=readersBiz.selectReaderById(Integer.parseInt(id));

if (readers!=null) {

//标红部分为精华，将对象转换为json格式

JSONArray jsonarray = JSONArray.fromObject(readers);

response.setContentType("text/html;charset=UTF-8");
