Question

有一个关于JSTL标签的非常简单的问题。我使用spring从后端获取数据并在JSP中显示。

拥有以下代码。我正在获取控制台中打印的每个标签的项目。但是相同的项目不会在表格行中打印/显示。

<table id="table_id" class="display">
<thead> 
    <tr>
        <th>Movie Name</th>
        <th>Movie Rating</th>
    </tr>
</thead>
<tbody>
    <c:forEach items="${model.movieslist}" var="movie">
    <tr>
        <td>${movie.name}</td>
        <td>${movie.rating}</td>
    </tr>

    </c:forEach>
</tbody>

public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
    // TODO Auto-generated method stub
    logger.info("returning hello view");
    List<Movie> moviesList = DbManager.getInstance().getMovies();
    ModelMap modelMap = new ModelMap();
    modelMap.addAttribute("movieslist", moviesList);
    return new ModelAndView("hello.jsp",modelMap);
}

电影域类

 package springapp.domain;

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
@Document(collection = "movie")
public class Movie {

    @Id
    public String _id;

    public String name;
    public String getId() {
        return _id;
    }

    public void setId(String _id) {
        this._id = _id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public float getRating() {
        return rating;
    }

    public void setRating(float rating) {
        this.rating = rating;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public float rating;
    public String date;

    @Override
    public String toString() {
        // TODO Auto-generated method stub
        return name;
    }

}

首先，你的jsp应该包含以下taglib

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

其次，您不需要使用$ {model.moviesList}来获取它，修改如下：

<c:forEach items="${movieslist}" var="movie">

JSTL项目未显示
