java - Spring MVC 模型不知道我的类

Question

我有一个应该直接解决的问题，但我显然做错了什么。我有一个用 Spring MVC 编写的简单网站。我的 JSP 模型不知道我的 NewItem 类..

@RequestMapping(value = "/", method = RequestMethod.GET)
public String newsFeed(Model model) {       
    try {
        initDB();
    } catch (Exception e) {     
        e.printStackTrace();
    }   

    ScanRequest scanRequest = new ScanRequest()
    .withTableName("Table1");
    ScanResult result = _database.get(scanRequest);         
    //This will just return a list with filled NewsItems from the database  
    List<NewsItem> list = getNewsItems(result.getItems());      
    model.addAttribute("newsList",list);        
    return "newsfeed";
}

public class NewsItem  {    
    private String url="";
    String getUrl(){
        return url;
    }
    void setUrl(String text) {
        url = text;
    }
    private String title="";
    void setTitle(String text) {
        title = text;
        Image = text;
    }

    String getTitle(){
        return title;
    }   
    String Description="";    
    String Image="";
    String Time="";
    String Since="";
}

And when im using ${newsList.getTile()} on the JSP side im getting a javax.servlet.jsp.JspException: javax.el.MethodNotFoundException: Method not found: class java.util.ArrayList.getTile() or java.lang.NumberFormatException: For input string:.. when Im trying to use ${newsList.Image}. Does anyone know what Im missing here?

stuff im using in jsp. taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" taglib prefix="spring" uri="http://www.springframework.org/tags" taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" page import="com.kiiak.tennman.NewsItem"

Answer 1

在 NewsItem 上调用 getTitle(注意拼写)，而不是在 List 本身上

<c:forEach var="newsItem" items="${newsList}">
    ${newsItem.title}
</c:forEach>
