我无法在我的 .jsp 页面上使用 ${} 表达式。

displayAllCustomers.jsp

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


<html>
<body>
<h3>Our Entire Customer Database</h3>
<ul>
<c:forEach items="${allCustomers}" var="customer">
<li>${customer.name}</li>
</c:forEach>
</ul>
</body>
</html>

dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans

<import resource="applicationContext.xml"/>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>


<bean name="/displayAllCustomers" class="mypackage.DisplayAllCustomersController">
<property name="customerManagementService" ref="customerManagementService" />
</bean>

</beans>

DisplayAllCustomersController.java

public class DisplayAllCustomersController {

private CustomerManagementService customerManagementService;
public void setCustomerManagementService(CustomerManagementService customerManagementService) {
this.customerManagementService = customerManagementService;
}

@RequestMapping("/displayAllCustomers")
public ModelAndView displayAllCustomers() {
List<Customer> allCustomers = customerManagementService.getAllCustomers();
return new ModelAndView("displayAllCustomers", "allCustomers", allCustomers);
}
}

当我显示页面时,我只看到标题“我们的整个客户数据库”。

这让我发疯,我不知道我错过了什么。

有人可以帮我理解为什么会这样吗?

非常感谢。

最佳答案

在顶部添加以下内容

<%@ page isELIgnored="false"%>
