java一些Spring模型属性没有显示在我的JSP中

1 年，3 月 Questions & Answers 988

我构建了一个简单的应用程序，使用JQuery data table+Spring+DB显示一些数据。数据如表所示

我最初构建了后端模型+DB（MongoDB）+视图，其中包含两个显示良好的属性

但是现在，当我向我的所有层添加更多属性时，JSP并不仅仅显示新添加属性的值

我已经检查了我的控制器是否在模型中发送正确的值作为对JSP的响应。JSP中的JSTL标记似乎没有显示正确的值

我的模型中有5个属性

姓名、年份、主管、评级、排名

在工作正常之前添加名称和年份

导演、评级和排名是后来添加的，不起作用。下面我给出了我的模型类的代码

下面是我的jSP代码

    <body>
     <h1>Welcome to My movie manager</h1>
        <h3>My ranking of movies</h3>
        <input type="button" value="Add a new movie" id="addbtn" />
        <input type="button" value="Select and remove a movie" id="delbtn" />
        <br><br>
        <table id="table_id" class="display">
        <thead> 
            <tr>
                <th>My Ranking</th>
                <th>Name</th>
                <th>Year</th>
                <th>Rating</th>
                <th>Director</th>

            </tr>
        </thead>
        <tbody>
            <c:forEach items="${movieslist}" var="movie">
            <tr>
                <td>$(movie.ranking)</td>
                <td>${movie.name}</td>
                <td>${movie.year}</td>
                <td>$(movie.rating)</td>
                <td>$(movie.director)</td>
            </tr>

            </c:forEach>
        </tbody>
    </table>
</body>
<script>

$(document).ready( function () {
    var table = $('#table_id').DataTable();
    $('#addbtn').click(addrow);
    $('#delbtn').click(delrow);


    table.on( 'click', 'tr', function () {
        if ( $(this).hasClass('selected') ) {
            $(this).removeClass('selected');
        }
        else {
            table.$('tr.selected').removeClass('selected');
            $(this).addClass('selected');
        }
    } );
} );
</script>
</html>

下面是我的Spring控制器

   @Controller
@RequestMapping("/movies")
public class MovieController{

    protected final Log logger = LogFactory.getLog(getClass());

    @RequestMapping(method = RequestMethod.GET)
    public String getMovies(Model model) {
        // TODO Auto-generated method stub
        logger.info("returning hello view");
        List<Movies> moviesList = DbManager.getInstance().getMovies();

        model.addAttribute("movieslist", moviesList);
        return "hello";
    }
}

下面是我的域类

 package springapp.domain;

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

    @Id
    public String _id;

    public String name;
    public String year;
    public String director;
    public float rating;
    public int ranking;
    public int getRanking() {
        return ranking;
    }

    public void setRanking(int ranking) {
        this.ranking = ranking;
    }

    public String getDirector() {
        return director;
    }

    public void setDirector(String director) {
        this.director = director;
    }

    public float getRating() {
        return rating;
    }

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

    public String getYear() {
        return year;
    }

    public void setYear(String year) {
        this.year = year;
    }

    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;
    }



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

}
