Question

我正在尝试开发基于Spring MVC和Apache Tiles的Java App。基本上一切都工作正常，直到我试图添加一些JavaScript到页面。比页面不显示。也许你有任何想法，为什么它不起作用？

因为没有js它工作正常我觉得没问题，如果我赢了t copy the Java classes, but only the jsp s和配置文件......

所以Spring-servlet是：

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

<context:component-scan base-package="com.kamirru" />

<context:annotation-config />



<bean id="viewResolver"
    class="org.springframework.web.servlet.view.UrlBasedViewResolver">

    <property name="sessionFactory" ref="sessionFactory" />
</bean>


<mvc:resources location="/resources/*" mapping="/resources/**"/>
<mvc:annotation-driven />

Tiles配置文件：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_2_0.dtd">

<tiles-definitions>

<!-- Widok: Header, body, footer -->

<definition name="nomenu" template="/WEB-INF/views/welcomeTemplate.jsp">
    <put-attribute name="title" value=""></put-attribute>
    <put-attribute name="header" value="/WEB-INF/views/header.jsp"></put-attribute>
    <put-attribute name="body" value=""></put-attribute>
    <put-attribute name="footer" value="/WEB-INF/views/footer.jsp"></put-attribute>
</definition>

<definition name="welcome" extends="nomenu">
    <put-attribute name="body" value="/WEB-INF/views/welcome.jsp"></put-attribute>
</definition>

</tiles-definitions>

web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>

        <param-value>/WEB-INF/config/sdnext-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>sdnext</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>

<!--    <servlet-mapping>
    <servlet-name>statCont</servlet-name>
    <url-pattern>*.js</url-pattern>
</servlet-mapping> -->

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>



</web-app>

最后是welcome.jsp：

<?xml version="1.0" encoding="ISO-8859-2" ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:spring="http://www.springframework.org/tags"
xmlns:h="http://java.sun.com/jsf/html" version="2.0">
<jsp:directive.page language="java"
    contentType="text/html; charset=ISO-8859-2" pageEncoding="ISO-8859-2" />
<jsp:text>
    <![CDATA[ <?xml version="1.0" encoding="ISO-8859-2" ?> ]]>
</jsp:text>
<jsp:text>
    <![CDATA[ <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> ]]>
</jsp:text>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>



<script type="text/javascript" src="${pageContext.request.contextPath}/resources/js_main/jquery.min.js"></script>
<script type="text/javascript"

<!-- 
 <script type="text/javascript" src="<c:url value="/resources/js_main/jquery.min.js" />"></script>
 <script type="text/javascript" src="<c:url value="/resources/js_slides/jquery.cycle2.js" />"></script>
 --> 



 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2" />
<title>Insert title here</title>
</head>
<body>
<center>

   <div class="cycle-slideshow"
    data-cycle-fx="scrollHorz"
  data-cycle-pause-on-hover="false"
  data-cycle-speed="2000"
>
<img src="${pageContext.request.contextPath}/resources/img/1.jpg"></img>
<img src="${pageContext.request.contextPath}/resources/img/2.jpg"></img>
</div>
</center>
</body>
</html>
</jsp:root>

正如您所见

<script type="text/javascript" src="${pageContext.request.contextPath}/resources/js_main/jquery.min.js"></script>
<script type="text/javascript"
src="${pageContext.request.contextPath}/resources/js_slides/jquery.cycle2.js"> </script>

未发表评论。如果我评论它，img将显示在网页上，但是当我试图包含javascripts时： - 仅显示页面标题（在本例中）

或者：

有一条错误消息“与元素类型”script“关联的属性”src“的值不得包含'＆lt;'字符。” （当使用{src =“时

你可以帮忙吗？我如何将js包含在该项目中？

Answer 1

Spring MVC中的Javascript库

put-list-attribute - 首先将list属性转换为脚本变量;之后，使用<c:forEach>标记进行迭代。然后，复合属性将一个接一个地呈现。

在下面的示例中，我将在spring tiles中导入jquery库

瓷砖定义

<definition name="DefaultTemplate" template="/WEB-INF/views/jsp/layouts/layout.jsp">
    <put-list-attribute name="javascripts">
            <add-attribute value="/resources/js/custom/jquery-1.4.4.min.js" />
            <add-attribute value="/resources/js/jquery/jquery-ui-1.8.6.custom.min.js" />
    </put-list-attribute>
</definition>

布局jsp页面

<c:forEach var="script" items="${javascripts}">
    <script src="<c:url value="${script}"/>"></script>
</c:forEach>

Answer 2

好的，我找到了解决方案......

创建jsp我通常选择JSP / JSF文件（xhtml，xml语法）。出于某种原因，在这些页面中运行jquery在我的项目中不起作用。我创建了一个简单的jsp文件（xhtml），js脚本和所有css运行没有问题。

如果有人知道原因，请分享:)

Spring MVC - Tiles，JSP页面包含js / jquery文件不起作用
