spring - 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:

<?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:context="http://www.springframework.org/schema/context"
       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/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.0.xsd
       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">

    <context:annotation-config />
    <dwr:configuration />
    <dwr:annotation-config />
    <dwr:url-mapping />

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

但是在添加了 DWR 相关的东西之后，Tomcat 基本上会在 <dwr:configuration /> 时抛出异常。被添加到 Spring XML 文件并在浏览器上抛出以下错误:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 24 in XML document from ServletContext resource [/WEB-INF/spring/webmvc-config.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 24; columnNumber: 26; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:configuration'.

在分析错误并查看 Tomcat 日志时，Tomcat 似乎无法读取模式文档，但这仅在它尝试在 DWR 的模式上这样做时才会发生 [即，http://www.directwebremoting.org/schema/spring-dwr/spring-dwr-3.0.xsd]并抛出如下异常:

[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>.

我试着用谷歌搜索并查看堆栈溢出的答案。流行的答案来自以下站点，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

让我认为这不是类路径问题的原因是，当我尝试在家运行时，同一个程序运行得非常好。即，Tomcat 能够访问和解析 dwr 模式，这在我看来是防火墙或代理问题。我们确实通过公司的代理访问互联网。但是我能够从我的浏览器完美地访问所有 DWR 模式。

这是代理问题吗？如果是这样，我如何将代理添加到 Tomcat 的配置中。此外，我很困惑为什么只有 DWR 模式无法访问，而 w3.org 和 spring.org 模式运行良好。 如果我对技术方面的理解有缺陷，请指出。

最佳答案

一年前我遇到了 DWR XML Scheme 问题(版本 3.0 M1)。他们把 spring-dwr-2.0.xsd 和 spring-dwr-3.0.xsd 弄得一团糟，并且没有在 jar 中添加 3.0 xsd 的 spring.schema 位置。 -- 可能你也有同样的问题。但首先要确保你部署的 dwr.jar 是正确的!

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

那么我的解决方案将帮助您。 (如果 dwr.jar 包含该行，则问题出在另一行。)

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。

要构建这样一个 jar:

下载 2 个 dwr xsd jar(spring-dwr-2.0.xsd 和 spring-dwr-3.0.xsd)并将它们放入包 org .directwebremoting.spring

然后将这个 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

(文件必须有一个换行符!-我不能让它在 SO 中可见)

不要将 dwr-xsd.jar 和 dwr.jar 添加到您的应用程序。
