Spring 3.0.5 / Tiles 2.2 错误

Question

我有一个在生产环境中使用的大型应用程序。我的图块设置很复杂，每页有很多图块。除了一件事之外，该应用程序运行良好。启动服务器后，第一个页面加载会抛出异常，

apache.commons.digester.Digester at line 789/Digester.getParser

它会抛出以下错误：

UnsupportedOperationException:: This parser does not support specification "null" version null" 

令人惊奇的是，此错误仅发生在第一个页面加载上，所有后续加载都工作正常。寻求这方面的帮助，请让我知道您需要什么信息。提前致谢。

这是嵌套的堆栈跟踪：

Answer 1

我今天遇到了这个问题，所以我想添加一篇文章，问题是因为 AppSensor （实际上是它的 ESAPI 2.0GA 依赖项），它包含两个不同版本的 xerces （来自 xom 依赖项的 2.6.1 和 2.8） .1 来自 antisamy 依赖项），但 2.6.1 出现在 2.8.1 之前，因此 2.8.1 不包括在内，并且会发生异常。

通过在 POM 中的 AppSensor 依赖项之前添加 2.8.1 依赖项来修复：

<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.8.1</version>
</dependency>
<dependency>
    <groupId>org.owasp.appsensor</groupId>
    <artifactId>AppSensor</artifactId>
    <version>${appsensor.version}</version>
</dependency>       

Answer 2

weblogic Windows 安装存在一些问题。
在 setDomainEnv.cmd 中设置此值并重新启动服务器。

set JAVA_OPTIONS=%JAVA_OPTIONS% -Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl

Answer 3

Spring 3.2.1 与tiles 2.2.2 导致了同样的错误。通过更新 xerxesimpl 解决了这个问题。这是 pom.xml 的片段

        <properties>        
    <java-version>1.6</java-version>            
    <org.slf4j.version>1.5.8</org.slf4j.version>
    <log4j.version>1.2.16</log4j.version>
    <xercesImpl.version>2.9.1</xercesImpl.version>
    <org.springframework-version>3.1.2.RELEASE</org.springframework-version>
    <tiles.core.api.servlet.jsp.version>2.2.2</tiles.core.api.servlet.jsp.version>
    </properties>

如果你做了一些愚蠢的事情，比如复制文件顶部的标签，你也可能会得到这个错误：
