如何在不修改 Tomcat 的 JVM 参数的情况下包含 xmlparserv2

Question

我需要在我的 Apache CXF Spring Web 服务应用程序中包含以下 jar。我用行家。我包括以下依赖项：

    <dependency>
        <groupId>manual</groupId>
        <artifactId>xmlparserv2</artifactId>
        <version>11.1.1.6.0</version>
    </dependency>

这是一个 JAR，是 Oracle 公共模块的一部分。我将它安装在本地 Maven 存储库中。当我运行我的服务包含这个 JAR 时，我收到以下错误：

据我了解，这是一个关于 XML 解析器冲突的问题。我读到这可以通过将此参数添加到 JVM 来解决：

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

事实上，这解决了问题。然而，这对我来说是不可取的，因为它迫使我向 JVM 添加参数，这可能会导致与应用服务器上部署的其他资源发生冲突（例如 Tomcat）。我需要知道是否有办法解决此错误 而无需 向 JVM 添加参数。例如，通过向 Spring 配置文件添加一些内容，或类似的内容。

Answer 1

好的，我明白了。我必须包括这些依赖项。

    <dependency>
        <groupId>xerces</groupId>
        <artifactId>xercesImpl</artifactId>
        <version>2.11.0</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>xalan</groupId>
        <artifactId>xalan</artifactId>
        <version>2.7.1</version>
        <scope>runtime</scope>
    </dependency>

我不得不在运行时强制包含它们。这会强制框架在运行时使用 xercesImpl 而不是 xmlparserv2。我必须包含 xalan 以便生成的 WSDL 可以包含自定义类型，否则，服务可以工作，但生成的 WSDL 有一个没有定义类型的空部分。
