Java:Spring:阅读spring context.xml时出现XML冲突重复定义:'identifiedType'

Question

任何建议或帮助非常感谢.

有许多参考链接,但没有明确的解决方案.我想知道Spring项目如何与返回XMLType输出的PLSQL过程交互.你需要XMLParser,然后我们都会在使用Spring时遇到这个错误.有没有人有任何建议？

我有一个运行良好的Maven spring应用程序(mvc/Rest),我添加了以下依赖项来与PLSQL程序进行交互,

    <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc6</artifactId>
        <version>11.2.0.4</version>
    </dependency>
    <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>xdb6</artifactId>
        <version>11.2.0.4</version>
    </dependency>
    <dependency>
        <groupId>com.xmlparserv2</groupId>
        <artifactId>xmlparserv2</artifactId>
        <version>11.1.1</version>
    </dependency>

包括后xdb6和xmlparserv2,我得到Spring应用程序启动时,提示以下错误(运行时服务器)

假设我删除了Line16及其引用,然后在不同的行抛出相同的错误,比如第13行

根据公布的答案,它说可以提供快速解决方案,

要覆盖xmlparserv2.jar所做的更改,请将以下JVM属性添加到应用程序服务器启动参数中.java.xml.parsers.FactoryFinder逻辑将首先检查环境变量.

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

 -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl

 -Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

建议不要这样做,如链接 https://community.oracle.com/thread/1080787中所述

这里提到了另一个解决方案(与hibernate相关,但类似):在hibernate中使用Oracle XMLType列

在maven spring项目中,通过在%PROJECT_HOME%/ src/main/resources目录中创建以下文件来覆盖xmlparserv2.jar设置:

%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl as the default)
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.SAXParserFactory (which defines com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl as the default)
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.transform.TransformerFactory (which defines com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl as the default)

这对我来说并不清楚.

如何将这些文件删除到上述目录？这是推荐的解决方案吗？

我尝试添加VM参数-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl ,但它确实有效.

但是寻找替代的,更合适的解决方案.这只是一种解决方法.当应用程序通过Jenkins部署到服务器时,不适合设置与XML解析器相关的这些VM参数设置.

@Ian Roberts的答案解决了这个问题.我清理了context.xml以始终使用xsd的版本号.

这篇文章已经很老了,但无论如何我今天碰到了这个帖子,找到了原因和不同的解决方案.事实证明,当您使用Oracle的maven repo通过maven引入oracle jdbc驱动程序依赖项时,它会传递性地获取其他库,这会在解析XML时导致此问题.我刚刚排除了oracle驱动程序的传递依赖项,一切正常.我认为在运行时根本不需要那些额外的库.

如果你的pom中有这个:

<dependency>
    <groupId>com.oracle.jdbc</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.2</version>
</dependency>

这是依赖树:

• ojdbc7:12.1.0.2
  • xdb6:12.1.0.2
  • orai18n:12.1.0.2
  • xmlparserv2:12.1.0.2 < - 罪魁祸首
  • oraclepki:12.1.0.2
  • osdt_cert:12.1.0.2
  • osdt_core:12.1.0.2

所以你可以像这样排除违规库:

<dependency>
    <groupId>com.oracle.jdbc</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.2</version>
    <exclusions>
        <exclusion>
            <artifactId>xmlparserv2</artifactId>
            <groupId>com.oracle.jdbc</groupId>
        </exclusion>
    </exclusions>
</dependency>

我实际上排除了所有传递依赖,并且一切似乎都很好.我不确定它们是否真的被使用过.我不这么认为,因为包含jdbc库的手动方式是简单地下载ojdbc jar.

这里有你的解决方案.

-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl`

Answer 3

schemaLocation是versioned(spring-beans-3.2.xsd)和unversioned(spring-tx.xsd)模式名称的混合.您应该始终使用一种风格或另一种风格,而不是将两者混合使用.我怀疑这里发生的是你明确指的是spring-beans的3.2版本,但你的一个未版本化的模式导入了同一模式的不同版本,导致两个相互矛盾的定义beans:identifiedType.
