后端传java复杂对象给前端js对象

jsp界面中将后端的java复杂对象传递给前端js对象的方法：

用JSP表达式--<%=%>加JSON数据转换
复杂对象需要转成JSON数据进行前后端传输，所以后端传值前、前端接收对象后都需要进行JSON数据处理。
后端代码：

@RequestMapping(value = "/user/common/defaultReport")
    public String defaultReport(HttpServletRequest req, Model model) {
        List<ActUserDeptAndFac> audfList = processCusReportService.getUDFList();
        req.setAttribute("audfList", audfList);
        return "user/activitiCommon/defaultReportView";
    }

前端代码jsp代码：

<%@ page import="com.factory.pro.entity.ActUserDeptAndFac" %>
<%@ page import="java.util.List" %>
<%@ page import="net.sf.json.JSONArray" %>
<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%
    List<ActUserDeptAndFac> audfList = (List<ActUserDeptAndFac>) request.getAttribute("audfList");
    String audfListStr = JSONArray.fromObject(audfList).toString();
%>
