java - Tomcat 上的 JSP 显示为源，而不是作为 JSP 处理

注意:这不是 this question 的副本.问题也指向了使用@RestController，他们的问题通过切换到@Controller 得到解决。我正在使用 @Controller 和 org.springframework.web.servlet.view.InternalResourceViewResolver

将 Web 应用程序从 WebSphere 移植到 Tomcat。以下内容在我的 mvc-config.xml 文件中:

<mvc:view-controller path="/" view-name="redirect:/dashboard"/>
<mvc:view-controller path="/login" view-name="login"/>

<mvc:view-controller path="/**.html" view-name="login"/>

<!-- Resolves view names to protected .jsp resources within the /WEB-INF/views directory -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/views/"/>
    <property name="suffix" value=".jsp"/>
</bean>

当我从 Tomcat 启动应用程序时，会显示以下测试(这是/WEB-INF/views/login.jsp 的文本，因此该部分可以正常工作):

<%@page contentType="text/html;charset=UTF-8"%>
<%@page pageEncoding="UTF-8"%>
<%@ page session="false" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<html>

    <style>
        h1{
            font-size:1.5em;            
        }

        h2{
            font-size:1.1em;
        }

        label, input{
            font-size:1.5em;
        }
    </style>
    <script type="text/javascript">
        jQuery(document).ready(function(){
            jQuery("#j_username").focus();
        });
    </script>

</head>
<body>

    <h1>Welcome to Our App</h1>

    <c:if test="${not empty param.login_error}">
      <div class='error' style="color: red;">
        Your login attempt was not successful, try again.
      </div>
      <div>
        If you need access to Our App, please contact your supervisor and they can get you access.
      </div>
    </c:if>

    <h2>Please login to continue.</h2>
    ...

IOW，正在显示 login.jsp 的完整内容，没有进行任何类型的处理。发生在 Firefox 和 Chrome，Tomcat 7.0.61 中。这是我的 Tomcat 日志文件中显示的内容:

我这里哪里设置错了？我是一个完整的 JSP 菜鸟。注意:我的 Controller 都不是“@RestController 他们都是@Controller

最佳答案

问题在于 WebSphere 包含 jSTL，而 Tomcat 不包含。 Maven POM 将 jSTL 作为“提供”。消除它可以解决问题。
