Question

我在使用列表对象列表填写jsp中的表时遇到问题。我似乎无法弄清楚我做错了什么，因为我看到它会告诉我按照我的方式去做。

这是我的jsp表：

<table id="budgetTbl" action="" method="post" class="table table-striped table-bordered table-hover">
    <thead>
        <tr>
            <th>Budget</th>
            <th>Projected</th>
            <th>Actual</th>
        </tr>
    </thead>
    <tbody>
        <c:forEach var="budget" items="${budgets}">
            <tr>
                <td>${budget.budgetName}</td>
                <td>${budget.budgetAmount}</td>
                <td>${budget.actual}</td>
            </tr>       
        </c:forEach>
    </tbody>
</table>

这是我的控制器中的代码：

@RequestMapping(value="budget" , method = RequestMethod.GET)
public String getBudget(@ModelAttribute("user") User user, Model model) {

    List<Budget> budgets = budgetService.getBudgets(1);

    model.addAttribute("budgets", budgets);

    if(user.getLoggedIn())
        return "budget";
    else
        return "redirect:login.html";

}

我的豆子：

<jsp:useBean id="budget" class="com.lindeman.model.Budget"/>        
<jsp:setProperty name="budget" property="*"/>

budgetService：

@Service("budgetService")
public class BudgetServiceImpl implements BudgetService {

public List<Budget> getBudgets(int dateID) {

    List<Budget> budgets = new ArrayList<Budget>();


    try (CachedRowSet bud = DAO.getAllBudgets(dateID)) {

        bud.beforeFirst();
        while(bud.next()){

            Budget budget = new Budget();

            budget.setBudgetID(bud.getInt("BudgetID"));             
            budget.setDateID(bud.getInt("DateID"));             
            budget.setBudgetName(bud.getString("BudgetName"));              
            budget.setBudgetAmount(bud.getDouble("BudgetAmount"));              
            budget.setActual(bud.getDouble("Actual"));

            budgets.add(budget);

        }

    } catch (SQLException e) {
        DataDriver.processException(e);
    }


    return budgets;

}

}

你缺少taglib导入，把它放在jsp的顶部

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

使用弹簧mvc使用DTO在jsp中填充表
