前后端傳值（jsp+ajax+jstl）

處理流程(不清楚spring的流程)，所以現(xiàn)階段采用了傳統(tǒng)的處理流程

  1. 通過ajax 響應(yīng)前端的onload事件,然后發(fā)送請求

onload方法的標(biāo)簽有：<body>, <frame>, <frameset>, <iframe>, <img>, <link>, <script>

<script >
    function getStreamingMovies() {
        var Data = null;
        $.ajax({
                url:'http://localhost:8080/getStreamingMovies',
                type:"get",
                dataType:"json",
                success : function() {},
            }

        )
    }
/script>

<div class="leftside">
        <div class="hot">
            <div class="subtitle">
                <h2>精選電影推薦（8部）</h2>
                <a href="#">全部&gt;</a>
            </div>
            <div class="movies">
                <style onload="getStreamingMovies()"></style>
                <c:forEach items="${sessionScope.userStreamingRecommend}" var="item">
                    <a href="#" class="first">
                        <img src="${item.image_path.concat('poster.jpg')}" alt="movies" height="220" width="160" >
                        <!-- 后續(xù)添加寬高限制 -->
                        <div>${item.title}:${item.vote_average}</div>
                    </a>
                </c:forEach>
            </div>
        </div>

    </div>

2.將Ajax請求去響應(yīng)Rest層的getStreamingMovies

   //調(diào)用業(yè)務(wù)處理層的方法獲取實(shí)時推薦的電影信息
    @RequestMapping("/getStreamingMovies")
    public void getRealTimeMovies(HttpServletRequest request, HttpServletResponse response) throws IOException {
        response.getWriter().append("Served at: ").append(request.getContextPath());

        request.setCharacterEncoding("utf-8");
        response.setCharacterEncoding("utf-8");
        response.setContentType("text/html; charset=UTF-8");
        HttpSession session = request.getSession();
        PrintWriter out = response.getWriter();

        UserService userService = new UserService();
        RecommendService recommendService = new RecommendService();
        MoviesService moviesService = new MoviesService();
        String username =(String) session.getAttribute("username");
//        String username="kurumi";
        String userIdAndGenres = userService.getUserIdByUsername(username);
        String[] user = userIdAndGenres.split(":");
        ArrayList<Recommendation> streamingRecommendation = recommendService.getStreamingRecommendation(
                new GetMovieRequest(Integer.parseInt(user[0]), Constant.STREAMING_RECOMMEND_NUM));
        //當(dāng)前沒有實(shí)施推薦的項(xiàng)目
        if (streamingRecommendation==null) {
            streamingRecommendation = recommendService.getGenresTop(new GetTopMovieGenresRequest(user[1],Constant.STREAMING_RECOMMEND_NUM));
        }
        //根據(jù)電影id獲取詳細(xì)的電影詳細(xì)
        ArrayList<Movie> moviesList = moviesService.getMoviesList(streamingRecommendation);
        ArrayList<Movie> recommendList = InfoParse.movieImageParse(moviesList);


        session.setAttribute("userStreamingRecommend",recommendList);

    }

3.jsp頁面通過foreach標(biāo)簽庫獲得對應(yīng)的值

<style onload="getStreamingMovies()"></style>
                <c:forEach items="${sessionScope.userStreamingRecommend}" var="item">
                    <a href="#" class="first">
                        <img src="${item.image_path.concat('poster.jpg')}" alt="movies" height="220" width="160" >
                        <!-- 后續(xù)添加寬高限制 -->
                        <div>${item.title}:${item.vote_average}</div>
                    </a>
                </c:forEach>

附上 jsp代碼 只完成了部分功能
