json需要的jar

必须引入JSON-lib包，JSON-lib包同时依赖于以下的JAR包：

1.commons-lang.jar

2.commons-beanutils.jar

3.commons-collections.jar

4.commons-logging.jar

5.ezmorph.jar

6.json-lib-2.2.2-jdk15.jar

服务器端怎样向浏览器端返回json数据，直接用json工具包，把对象转化为json对象，然后

向浏览器输出就ok了

String totalString = "{\"total\":" + total + "}";
       JSONArray datasJson = JSONArray.fromObject(datas);
       JSONArray pageJson=JSONArray.fromObject(pager);
      // String dataString = "{\"total\":"+totalString+",\"datas\":" + datasJson.toString() +"}";
        String dataString = "{\"pageJson\":"+pageJson.toString()+"}";
        System.out.println("dataString:"+dataString);
       try {
               request.setCharacterEncoding("utf-8");
               response.setContentType("text/html;charset=UTF-8");
               PrintWriter out;
               out = response.getWriter();
               out.write(dataString);
               out.flush();
               out.close();
           } catch (IOException e) {
           }
