Tomcat无法读取架构文档

标签： spring tomcat proxy xml-parsing dwr

我们正在尝试为当前项目添加DWR，执行此操作的代码如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"

       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
       http://www.springframework.org/schema/beans

       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
       http://www.directwebremoting.org/schema/spring-dwr
       http://www.directwebremoting.org/schema/spring-dwr/spring-dwr-3.0.xsd">

    <dwr:controller id="dwrController" debug="true" >
        <dwr:config-param name="activeReverseAjaxEnabled" value="true"/>
    </dwr:controller>

但是在添加DWR相关内容之后，当<dwr:configuration />添加到Spring XML文件并在浏览器上抛出以下错误时，Tomcat基本上会抛出异常：

在分析错误并查看Tomcat日志时，看起来Tomcat无法读取架构文档，但只有当它尝试在DWR的架构上执行此操作时才会发生[即。http://www.directwebremoting.org/schema/spring-dwr/spring-dwr-3.0.xsd]并抛出例外情况如下：

[24 Feb 2012 17:02:17,272] WARN  [http-8040-1] org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Ignored X
ML validation warning
org.xml.sax.SAXParseException; lineNumber: 24; columnNumber: 26; schema_reference.4: Failed to read schema document 'htt
p://www.directwebremoting.org/schema/spring-dwr/spring-dwr-3.0.xsd', because 1) could not find the document; 2) the docu
ment could not be read; 3) the root element of the document is not <xsd:schema>.

我试过google并查看堆栈溢出的答案。流行的答案来自以下网站，声明它是类路径问题。

http://forum.springsource.org/showthread.php?35417-The-matching-wildcard-is-strict-but-no-declaration-can-be-foun-aop-scoped-proxy

Why isn't the Spring AOP XML schema properly loaded when Tomcat loads & reads beans.xml

是什么让我觉得它不是一个类路径问题，当我尝试在家跑步时，同一个程序运行得很好。即，Tomcat能够访问和解析dwr架构，这在我看来是防火墙或代理问题。确实，我们通过公司的代理访问互联网。但我能够完美地从浏览器访问所有DWR模式。

这是代理问题吗？如果是这样，我如何添加代理到Tomcat的配置。更多的是我很困惑为什么只有DWR架构是不可访问的，因为w3.org和spring.org架构完全正常。 请指出我对技术方面的理解是否存在缺陷。

3 个答案:

答案 0 :(得分：2)

我在一年前运行DWR XML Scheme问题（版本3.0 M1）。它们使spring-dwr-2.0.xsd和spring-dwr-3.0.xsd混乱，并且没有在其中添加3.0 xsd的spring.schema位置。 - 你可能遇到同样的问题。但首先要确保部署dwr.jar正确！

如果dwr.jar不包含包含以下行的文件META-INF\spring.schemas：

http\://www.directwebremoting.org/schema/spring-dwr-3.0.xsd=org/directwebremoting/spring/spring-dwr-3.0.xsd

然后我的解决方案会帮助你。 （如果dwr.jar包含该行，则问题是另一行。）

为了解决这个问题，我创建了一个新的jar（dwr-xsd.jar）文件，其中包含两个xsd文件和一个spring.schemas文件。

建造这样一个罐子：

下载2个dwr xsd广口（spring-dwr-2.0.xsd和spring-dwr-3.0.xsd）并将其放入包org.directwebremoting.spring

然后将此spring.schemas文件添加到META-INF目录：

 http\://www.directwebremoting.org/schema/spring-dwr-2.0.xsd=org/directwebremoting/spring/spring-dwr-2.0.xsd
 http\://www.directwebremoting.org/schema/spring-dwr-3.0.xsd=org/directwebremoting/spring/spring-dwr-3.0.xsd

（该文件必须并带有换行符！ - 我无法在SO中显示它）

不要向您的应用添加dwr-xsd.jar和dwr.jar。

答案 1 :(得分：1)

Ralph：我尝试了你的解决方案，一切看起来都不错，就像你在开始时所说的那样，spring.schemas被正确映射了。但很快我发现版本号是个问题。只是描述整个事情，所以它也可能对其他人有用。

我尝试了同样的（DWR架构工作）和没有互联网（不起作用）连接，这使我在SO中进行了以下讨论，这也与你的答案一起使用。

Spring schemaLocation fails when there is no internet connection

我首先看到映射不正确，我在XML for DWR中更改了bean定义，如下所示：

   http://www.directwebremoting.org/schema/spring-dwr
   http://www.directwebremoting.org/schema/spring-dwr-2.0.xsd">

来自现有的：

http://www.directwebremoting.org/schema/spring-dwr
http://www.directwebremoting.org/schema/spring-dwr/spring-dwr-3.0.xsd">

所以有两个问题

  1. http://www.directwebremoting.org/schema/spring-dwr-2.0.xsd“＆gt;
    2. 中缺少spring-dwr
  2. 版本从spring-dwr-3.0.xsd更改为spring-dwr-2.0.xsd

    3. ＃1的原因似乎是META-INF中的spring.schemas文件以这种方式映射

    http\://www.directwebremoting.org/schema/spring-dwr-2.0.xsd=org/directwebremoting/spring/spring-dwr-2.0.xsd

    对于第2点，基本上是DWR jar文件（名为dwr-3.0.M1.jar），虽然它的版本说3.0只包含xsd的2.0版本，并且在spring.schemas中有适当的映射。因此，当我改变它离线工作[虽然我还没有检查防火墙的办公网络。但我认为当它可以离线查找内容时，它不会尝试从在线获取。

    非常感谢你的回答

答案 2 :(得分：0)

可能不是你的情况。但在这种情况下，请做好清洁并重新打造。如果两个罐子出口，原因是较旧的弹簧罐和xsd。希望对其他人有所帮助....一般来说，这个异常会因为很多原因而被抛出。
